Excerpt from gizmodo.com
Graphene isn't the only game-changing material to come out of a lab. From aerogels nearly as light as air to metamaterials that manipulate light, here are six supermaterials that have the potential to transform the world of the future.
Self-healing Materials — Bioinspired Plastics

The human body is very good at fixing itself. The built environment is not. Scott White at the University of Illinois at Urbana Champlain has been engineering bioinspired plastics that can self-heal. Last year, White's lab created a new polymer that oozes to repair a visible hole. The polymer is embedded with a vascular system of liquids that when broken and combined, clot just like blood. While other materials have been able to heal microscopic cracks, this new one repaired a hole 4 millimeter wide with cracks radiating all around it. Not big deal for a human skin, but a pretty big deal for plastic.
Engineers have also been envisioning concrete, asphalt, and metal that can heal themselves. (Imagine a city with no more potholes!) The rub, of course, lies in making them cheap enough to actually use, which is why the first applications for self-healing materials are most likely to be in space or in remote areas on Earth.
Thermoelectric Materials — Heat Scavengers

If you've ever had a laptop burn up in your lap or touched the hot hood of car, then you've felt evidence of waste. Waste heat is the inevitable effect of running any that device that uses power. One estimate puts the amount of waste heat as two-thirds of all energy used. But what if there was a way to capture all that wasted energy? The answer to that "what if" is thermoelectric materials, which makes electricity from a temperature gradient.
Last year, California-based Alphabet Energy introduced a thermoelectric generator that plugs right into the exhaust pipe of ordinary generator, turning waste heat back into useful electricity. Alphabet Energy's generator uses a relatively cheap and naturally occurring thermoelectric material called tetrahedrite. Alphabet Energy says tetrahedrite can reach 5 to 10 percent efficiency.
Back in the lab, scientists have also been tinkering with another promising and possibly even more efficient thermoelectric material called skutterudite, which is a type of mineral that contains cobalt. Thermoelectric materials have already had niche applications—like on spacecraft—but skutterudite could get cheap and efficient enough to be wrapped around the exhaust pipes of cars or fridges or any other power-hogging machine you can think of.

Perovskites — Cheap Solar Cells

The biggest hurdle in moving toward renewable energy is, as these things always are, money. Solar power is getting ever cheaper, but making a plant's worth of solar cells from crystalline silicon is still an expensive, energy-intensive process. There's an alternative material that has the solar world buzzing though, and that's perovskites.
Perovskites were first discovered over a century ago, but scientists are only just realizing its potential. In 2009, solar cells made from perovskites had a solar energy conversion efficiency of a measly 3.8 percent. In 2014, the number had leapt to 19.3 percent. That may not seem like much compared to traditional crystalline silicon cells with efficiencies hovering around 20 percent, but there's two other crucial points to consider: 1) perovskites have made such leaps and bounds in efficiency in just a few years that scientist think it can get even better and 2) perovskites are much, much cheaper.
Perovskites are a class of materials defined by a particular crystalline structure. They can contain any number of elements, usually lead and tin for perovskites used in solar cells. These raw materials are cheap compared to crystalline silicon, and they can be sprayed onto glass rather than meticulously assembled in clean rooms. Oxford Photovoltaics is one of the leading companies trying to commercialize perovskites, which as wonderful as they have been in the lab, still do need to hold up in the real world.

Aerogels — Superlight and Strong
Image credit: NASA
Aerogels look like they should not be real. Although ghostly and ethereal, they can easily withstand the heat of a blowtorch and the weight of a car. The material is almost what exactly the name implies: gels where where the liquid has been replaced entirely by air. But you can see why it's also been called "frozen smoke" or "blue smoke." The actual matrix of an aerogel can be made of any number of substances, including silica, metal oxides, and, yes, also graphene. But the fact that aerogel is actually mostly made of air means that it's an excellent insulator (see: blowtorch). Its structure also makes it incredibly strong (see: car).
Aerogels do have one fatal flaw though: brittleness, especially when made from silica. But NASA scientists have been experimenting with flexible aerogels made of polymers to use insulators for spacecraft burning through the atmosphere. Mixing other compounds into even silica-based aerogels could make them more flexible. Add that to aerogel's lightness, strength, and insulating qualities, and that's one incredible material.

Metamaterials — Light Manipulators
If you've heard of metamaterials, you likely heard about it in a sentence that also mentioned "Harry Potter" and "invisibility cloak." And indeed, metamaterials, whose nanostructures are design to scatter light in specific ways, could possibly one day be used to render objects invisible—though it still probably wouldn't be as magical as Harry Potter's invisibility cloak.
What's more interesting about metamaterials is that they don't just redirect visible light. Depending on how and what a particular metamaterial is made of, it can also scatter microwaves, radiowaves, or the little-known T-rays, which are between microwaves and infrared light on the electromagnetic spectrum. Any piece of electromagnetic spectrum could be manipulated by metamaterials.
That could be, for example, new T-ray scanners in medicine or security or a compact radio antennae made of metamaterials whose properties change on the fly. Metamaterials are at the promising but frustrating cusp where the theoretical possibilities are endless, but commercialization is still a long, hard road. [Nature, Discover Magazine]
Stanene — 100 percent efficient conductor

Like the much better known graphene, stanene is also made of a single layer of atoms. But instead of carbon, stanene is made of tin, and this makes all the difference in allowing stanene to possibly do what even wondermaterial extraordinaire graphene cannot: conduct electricity with 100 percent efficiency.
Stanene was first theorized in 2013 by Stanford professor Shoucheng Zhang, whose lab specializes in, along other things, predicting the electronic properties of materials like stanene. According to their models, stanene is a topological insulator, which means its edges are a conductor and its inside is an insulator. (Think of a chocolate-covered ice cream bar. Chocolate conductor, ice cream insulator.)
This means stanene could conduct electricity with zero resistance even, crucially, at room temperature. Stanene's properties have yet to been tested experimentally—making a single-atom sheet tin is no easy task—but several of Zhang's predictions about other topological insulators have proven correct.
If the predictions about stanene bear out, it could revolutionize the microchips inside all your devices. Namely, the chips could get a lot more powerful. Silicon chips are limited by the heat created by electrons zipping around—work 'em too fast and they'll simply get too hot. Stanene, which conducts electricity 100 percent efficiency, would have no such problem. [SLAC, Physical Review Letters, Scientific American]

| “Penghu 1,” the newly discovered human with large teeth, is another piece of critical evidence suggesting that other humans besides Homo sapiens lived in Asia from 200,000 to 10,000 years ago. |
Paleontologists have identified the first known prehistoric human specimen from Taiwan, which may have been part of a species that lived alongside modern humans until as recently as 10,000 years ago.
“Penghu 1,” the newly discovered human with large teeth, is another piece of critical evidence suggesting that other humans besides Homo sapiens lived in Asia from 200,000 to 10,000 years ago.
Among the species that lived in Europe within that period were Neanderthals, Denisovans and Homo floresiensis The Penghu 1, which has been described in the most recent issue of Nature Communications, has added to that sizable list of humans that may have lived with and interbred with modern humans.
“The available evidence at least does not exclude the possibility that they survived until the appearance of Homo sapiens in the region, and it is tempting to speculate about their possible contact,” said the study’s co-author Yousuke Kaifu, an associate professor in the Department of Biological Sciences at The University of Tokyo, to Discovery News.
Kaifu, along with the paper’s lead author Chun-Hsiang Chang, and their team have studied the new human’s remains, primarily a jawbone that still contains big teeth. The jawbone was found by fishermen off the Taiwanese coast in the Penghu Channel. They then sold it to a local antique shop where it was found and bought by the collector Kun-Yu Tsai, who donated his collection to the National Museum of Natural Science in Taiwan. It then caught the eye of Chang, who works at the museum as a geologist.
Chang and his team now believe that the Penghu 1 could suggest a new species of human or at least a distinct regional group of Homo erectus. He suspects that the jawbone belonged to an elderly adult due to the worn state of the teeth. Unlike Homo floresiensis, the Penghu 1 grew to adult stature and lived on the Asian mainland.
“The associated faunal remains suggest that the area was a relatively open, wet woodland,” said Kaifu. “This is because of the presence of large-bodied mammals, such as elephants (Stegodon), horses and bear, but the fauna also included animals that prefer marshlands in a hot and humid climate, such as water buffaloes.”
All of these aspects would seem very attractive to modern humans, as well as the prehistoric humans they co-existed with. Although Penghu 1 is clearly not a modern human, its jaw bears many similarities to Homo erectus. Very little is known about human evolution in Asia, so this is a considerably welcome discovery, as fossils from much earlier periods discovered in China have offered valuable insights into what a Cretaceous ecosystem looked like. There are also many similarities between Penghu 1 and the Peking Man remains from Zhoukoudian, China, although the former appears to be much more primitive. It has also been compared to the archaic Homo heidelbergensis and also Denisovan remains.

| December is usually marked by a series of meteor showers. Geminid meteors (like the one seen in this picture of Florida) light up the skies at the beginning of the month, while the Ursids - which peak Monday night (Dec. 22) - put on a show just before Christmas. |
Excerpt from space.com
The Ursid meteor shower peaks tonight, and it should be a great show.
When skywatchers think of meteor showers during the month of December, the Geminid shower (which peaked earlier this month) usually comes to mind. But the Ursid meteor shower — peaking tonight and into the wee hours of Tuesday (Dec. 23) morning — should also offer skywatchers a good view this year.
Even if you can't see tonight's meteor shower due to light pollution or bad weather, you can still catch the Ursids online thanks to the Slooh Community Observatory. Tune in for Slooh's Ursid meteor shower webcast tonight starting at 8 p.m. EST (0100 Dec. 23 GMT) live on Space.com. You can also watch the webcast directly through Slooh.
The Ursids are so named because they appear to fan out from the vicinity of the bright orange star Kochab, in the constellation of Ursa Minor, the Little Bear. Kochab is the brighter of the two outer stars in the bowl of the Little Dipper (the other being Pherkad), that seem to march in a circle like sentries around the North Star, Polaris. These meteors are sometimes called the Umids, in a rather unsuccessful attempt to make clear that their radiant is in Ursa Minor, not Ursa Major.
The fact that Kochab is positioned so near to the north pole of the sky means that this star almost never sets for most viewers in the Northern Hemisphere. And since the Ursids seem to fan out from this particular region of the sky, you have a reference point to look for these faint, medium-speed meteors all through the night if you care to.
The fact that the shower peaks tonight is good news for observers braving the cold to see the display. The moon is just one day past its new phase, meaning that light reflected from Earth's natural satellite won't wash out the shower.

The towering dunes on Saturn's largest moon, Titan, may look similar to the sandy hills of Earth's Sahara, but their origins are completely different, researchers say. Instead of forming continuously over time like on Earth, Titans dunes are forged by short, powerful rogue winds.
Reaching heights of more than 300 feet (91 meters), the dunes of Titan present a puzzling mystery: they seem to form in the opposite direction as Titan's steady east-to-west winds. Two new studies suggest that rare bursts of wind blowing westward are responsible for these enormous structures. The findings shed light on the remote satellite that shares many qualities with Earth.
"It was a bear to operate, but Dr. Burr's refurbishment of the facility as a Titan simulator has tamed the beast. It is now an important addition to NASA's arsenal of planetary simulation facilities," John Marshall, of the SETI Institute, and a co-author on the new research, said in the statement.
Titan's dunes are not made of the kind of sand found in deserts on Earth, but a more viscous material. Scientists don't know exactly what it is, only that it is made of hydrogen and carbon — two ingredients that can be used to create a laundry list of different materials on Earth, from methane to paraffin wax. According to Burr, the hydrogen-carbon material may coat particles of water ice.
The researchers found that the regular east-to-west winds are not strong enough to shape the viscous material into the massive dune shapes that are observed. Instead, they believe the dunes are shaped by short, rapid bursts of westerly wind. The winds on Titan "occasionally reverse direction and dramatically increase in intensity due to the changing position of the Sun in its sky," the statement said.

A Neptune-size planet beyond the solar system has telltale traces of water vapor in its atmosphere, making it the smallest exoplanet known to have the wet stuff yet, scientists say.
Several massive Jupiter-size giants have had the components of their atmosphere examined, but until now, the atmospheres of smaller planets have proved more elusive. In this new study, scientists discovered traces of water on the alien planet HAT-P-11b, which orbits a star 124 light-years from Earth in the constellation Cygnus.
"Water is the most cosmically abundant molecule that we can directly observe in exoplanets, and we expect it to be prevalent in the upper atmospheres of planets at these temperatures," lead author Jonathan Fraine said in an email interview. Fraine, a graduate student at the University of Maryland, worked with a team lead by Drake Deming, also of the University of Maryland.
"Detecting it is both a confirmation of our theories and revealing for the bulk of the spectrum that we can observe," Fraine told Space.com.
This artist’s illustration depicts the alien planet HAT-P-11b, which shows signs of water in its atmosphere, as the exoplanet crosses in front of its parent star. As starlight passes through the puffed-up atmosphere surrounding the planet, shown here in orange, scientists can detect its composition.

Detecting alien planet atmospheres

As a planet passes, or transits, between Earth and its sun, it blocks light from the star. The dip in light is how many exoplanets are first found. But these transits also allow astronomers to study the atmospheres of exoplanets. By observing the spectrum of light that passes through an exoplanet’s atmosphere, scientists can determine what it is made up of.
For HAT-P-11b, a planet roughly four times the radius of Earth, that makeup is 90 percent hydrogen, with traces of water vapor. The Neptune-size planet orbits its sun every five days, at a distance that is only one-twentieth of the Earth-sun distance (which is 93 million miles, or 150 million kilometers). As a result, the temperature climbs higher on HAT P-11b than it does on gas giants in the solar system, reaching a sizzling 1,120 degrees Fahrenheit (605 degrees Celsius).
Scientists have been studying the atmospheres of Jupiter-like planets for years, but smaller planets produce a smaller signal that is more challenging to observe. For the new study, researchers examined the atmospheres of four other smaller exoplanets — two roughly the size of Neptune and two smaller super-Earths — but the results were disappointingly featureless.
"We do indeed have the technology — the resolution — to observe Neptune-size exoplanets, and even super-Earths," Fraine said.
But the chemical compositions of the other four planets were blocked by a familiar phenomenon — clouds.
"We've just been seeing a whole lot of nothing," Eliza Kempton, of Grinnell College in Iowa. Kempton models planetary atmospheres but was not involved in the research.
This artist's illustration shows what the skies may look like on different alien planets. On the left is a cloudy planet, while on the right is a planet with clear skies that may resemble the sky of exoplanet HAT-P-11b, a Neptune-size world thought to have water in its atmosphere.

Kempton added that the flat, featureless signals observed for the other planets were attributed to clouds or hazes in the upper atmosphere. The high clouds blocked light from the star, keeping it from penetrating through to the observers' side of the planet and leaving scientists unable to characterize the chemicals in the atmosphere.
"It's not crazy to think that there should be clouds in these exoplanet atmospheres, because we see clouds in all the planetary atmospheres in our solar system," Kempton said.
Although the hot, Neptune-size planet lives in a different environment from the icy giants in the solar system, it is similar to one of the four smaller planets whose atmosphere had already been studied. Those planets are known as GJ436b, GJ1214b, HD97658b and GJ3470b.
HAT-P-11b is only slightly larger and warmer than the alien planet GJ436b, making them good to compare to one another because one has clouds and one does not, Fraine said.
"I like to consider them the bigger version of the Earth-Venus twin pair," Fraine said of the planets HAT-P-11b and GJ436b.
"They are basically the same mass, radius and temperature, but small changes in the formation, or even these bulk properties, may be causing vast changes in the atmospheric composition."
The research is detailed in the Sept. 25 issue of the journal Nature, along with a commentary article by Kempton.
A planet's upper atmosphere results from what happens both above and below it. The balancing act involves irradiation from its star and from cosmic rays on the outside, as well as the chemical and dynamical systems lower in the atmosphere, Fraine explained.
"If we know the input from above — the host star — and the upper atmosphere from our observations, then the missing piece of the puzzle is the interior composition," he said.
Although the interior of a planet is complex, Fraine called the newly characterized atmosphere "a great step forward in solving the puzzle."
The composition of the small planet's atmosphere also supports the core accretion model of planetary formation, where smaller particles combine to create larger and larger particles, eventually reaching planet-size proportions.
"Core accretion predicts that planets are built from the inside out," Fraine said.
"Measuring that HAT P-11b likely has a relatively hydrogen-poor atmosphere implies that it was formed from rocky material that later acquired a thick atmosphere above it, which is what the core-accretion model predicts."
Had the planet formed along the lines of the competing gravitational instability model, its composition and that of its atmosphere should bear a stronger similarity to its star than what was measured by scientists.
Because of its crucial role in the balancing act, the water vapor detected in the exoplanet's atmosphere played an important part in modeling its formation and evolution.
"In the long run, if we can detect water, methane, carbon monoxide, carbon dioxide, etc., in dozens to hundreds of exoplanet atmospheres of various bulk properties, then we will be able to paint a much clearer picture of how planets form, and, likewise, how Earth formed," Fraine said.
"This was just one of the beginning brush strokes to painting the full picture of how planets, as well as ourselves, were formed."
This is what we have done for Astrotheme's visitors, trying to use everyday words devoid of technical jargon, with no historical or specialised argumentation, and with the only aim to reach to as many persons as possible, yet without proselytizing. Just a few judgments coming from experience, a pragmatic vision of this tool for knowledge, which is what astrology is all about.
For the illustration of this non-technical article, it became rapidly obvious that astronomy images are needed... The staggering sight of certain galaxies or nebulae is not only splendid but enables to open one's mind towards... more consciousness and a more intense feeling of being alive.
Of course, the purpose is not to convince. Indeed, in politics as well as in spirituality, to change direction is a complex issue. As far as the quite bizarre field of astrology is concerned, irrational behaviours occur quickly, usually with a little disdainful smile from those who, obviously, have been beyond the naive propensity to believe anything, to dream blissfully, and to delude themselves about a necessarily silly system because it offers off the beaten path possibilities, which other human disciplines do not.
The list of the authors of scornful smiles towards astrology is quite long, just as long as the list of more open-minded people who, either have tried themselves to learn this tool which astrology is – which, like psychology or history, is not a science – and became convinced that it works or at least has some degree of efficiency, or because they no time or no interest, leave the door open, thinking "finally, why not?", after all, one does not know much, would it be solely in the area of the spouting of the thought – WHO handles thought at the moment it emerges... - or about physical laws for which the 21th century is mere prehistory, as all scientists know. Indeed, life is evolution, knowledge is not static, and the only mistake which must not be made is to gorge oneself with certainties, including that which consists in associating "too good" results with absolute scientific impossibility.
I believe that my experience is quite similar to that of everybody, i.e. that of a person who, a priori, before discovering it, was "against" astrology and considered it... crap meant for gullible people, or in the best case, an idle fancy with a tinge of poetry in which all the intellectual energy spent was finally used to create a nice virtual world and arouse pleasure.
Paradoxically enough, relatively few astrologers are interested in astronomy. This is not my case. I even dreamed I would become an astronomer when I was small, and nowadays I feel the need to have a telescope at home, even though... I seldom use it because, unfortunately, the sky above the region of Paris is too polluted.
As I flicked through the pages, I was a bit amused to see the natal charts of historical personages, quite rigorous rules, an apparently sound functioning, and I thought that for once, I ought to read an astrology book, and at least, this one does not seem too naive.
In addition, there were a few recipes for the compatibility of couples, and since I was in love of one of my school comrades, in that Terminale C class (In the French education system, the last year of secondary school with a maths option), I thought, well, I am going to have fun and see whether, according to astrology, my compatibility with this beautiful brunette, the sight of whom would pierce my heart, is good or not!
With a good dose of scepticism and quite negative preconceptions, I started to learn to erect a natal chart, interpret it, and become initiated into all the predictive techniques, synastry, and other relishes having the charm of that which is unknown.
Since this article is not a book, it is necessary to get to the heart of the matter. Actually, I realised quickly that among the concepts of signs, houses, planets, houses in signs, planets in signs, rulership, aspects, nature of the planets, etc. it would take some time before being rewarded, venturing into uncertain territory alone, and interpreting charts without opening astrology books every thirty seconds.
Indeed, to my view, the first obstacle for anyone willing to get an idea about astrology is the huge contrast between serious astrology on the one hand, and on the other hand, the ordinary media and its horoscopes by signs or by decans – which are of no value, it is necessary to say so, absolute void, and the biggest hoax because a natal chart cannot be reduced to the position of the Sun in one of the zodiacal signs. Absurd columns with equally stupid predictions – here again, and it is difficult to refrain from giving names, be it to quote people who saw Kerry as the winner of the American elections in Telestar (A popular French television weekly) or in other magazines, or in general a little bit everywhere because it cannot be repeated often enough that there are two types of astrology, that of horoscopes in magazines which are nonsense, a mere commercial lottery. From this perspective, it is easier to understand the disdainful smiles of those mentioned earlier, and I particularly think of Guy Carlier (A French TV presenter and humorist), whom I nevertheless find quite pleasant, and of Alain Gillot-Pétré (He was a French TV meteo presenter), a declared enemy of astrologers. I remember for instance a TV programme featuring Paco Rabanne (He became famous as a fashion designer. He is not an astrologer but a weird visionary, also quite nice), and gorgeous Elisabeth Tessier (A professional French astrologer whom the late President François Mitterrand consulted. The thesis she defended at La Sorbonne University was the subject of a hot controversy) who was castigated by Guy Carlier... Thus, there is a big discrepancy between junk astrology and genuine astrology. The latter consists in extracting information from an exact natal chart based on a date of birth and location, and whenever possible a time of birth, and to deduct relevant results from this chart.
The weird and unique feeling of infinity which emerges from the sky when one gazes into space is one of the numerous methods for starting a meditation on the purpose of one's life.
Therefore, a lot of time is required because without learning by rote numerous dozens of basic notions, it is very difficult not to get lost. Of course, one can have fun, but if one expects some degree of proficiency or just wants to be able to follow the rules of this tool, one will have to spend several months studying.
I shall briefly address a few other obstacles which claim so-called scientific bases and may prompt doubts, discouraging people who are curious about astrology even before they get a chance to start studying it. I think for instance of such a statement as "astrology is bullshit since everyone knows that owing to the precession of the equinoxes, and when one says that the Sun is in Aries although in fact, it's been a long time since it has left this constellation." This is obviously stupid because by definition, in astrology, signs do not represent the constellations bearing the same name, but they refer to the immutable cycle of the seasons. Thus, the sign of Aries corresponds to the spring equinox in the Northern hemisphere, and not to the stretch of space occupied by the constellation of Aries.
But I will not elaborate any further on these technical details because they are not the focus of this article, the purpose of which is only to give a testimony and to state that astrology works, in the light of an experience and a practice which cover a span of thirty years plus.
So, after a few weeks, astrology became clearer for me. Actually, I understood that finally, there were three essential functions and a fourth one as the wild card, if I may say so. First, there is the astrology which analyses the personality, the character, the motivations, the typology, and the behaviour. Then, there is a second astrology, well-known, which checks the past and analyses the present by superimposing the positions of the planets at a given period on the planets of the natal chart, using various techniques such as transits, solar revolutions, progressions, etc. Lastly, there is the astrology which compares two charts in order to understand the relations between two individuals who may be more or less compatible.
After the feeling of infinite in space, the questioning about... whatever pre-existed automatically arises. The sensation of the infinity of time, the research of the causes, and the voyage back beyond them necessarily makes a normally constituted human being feel dizzy. Such vertigo arouses a stronger desire to understand the meaning of all this and therefore, the commencement of spiritual quest.
For all four sections, it is clear that people don't have the same propensity to "believe" or not. Many people have no problem acknowledging that astrological portraits are mind-boggling because they are so accurate. I leave out the cases which present no problems, i.e. most of them, or the cases of people of good faith, again the majority, and I address only the case of sceptical people.
Regarding forecasts, it is slightly more delicate. Recalcitrant people are usually more numerous, and there are even some astrologers who want to limit astrology to the functions of personality analysis and are adamant about this. The good-looking and talented Françoise Hardy (A famous French composer and singer of the '60s. She authored a book on astrology) is one of those people. The other sections of astrology seem too risky or difficult to them, unless they deem them... impossible for x reasons known to themselves only.
Regarding couple's compatibility, also referred to as synastry, the subject is less known and better accepted because if one considers that astrology can analyse the personality, why couldn't it analyse two personalities and see if those two get along well or not...
Astrology is a mere set of efficient techniques for those who practice it and those who seek advice from it. However, although astrology and spirituality are disjoint, questions on human being, which the former necessarily indirectly arises, create... a bridge towards the quest for Reality.
Let's get back to astrology learning. Once the two obstacles mentioned above are overcome, i.e. the venom of the ignorant mass and its bitter judgment, castigating with a conceited smile any effort made towards the shameful direction in which astrology is, and the fact that many long months will have to be spent to understand and master the concepts and the rules – actually, in my view, this is not enough, and I believe that after a whole year of reading and practice, one gets a good idea. After 5 years, one is able to make a few interpretations, after 15 years, one has good bases, and after 30 years, although one still keeps on learning, one has some good reflexes which enable to avoid making mistakes. It is after this period that amazement starts...
Bewilderment starts with the portraits. The hurdle lies in establishing the hierarchy of values and discarding whatever is superfluous. Indeed, the beginner tends to look at tons of details and get lost in a whole set of numerous meanings. Once this difficulty is solved, it is true that, if the sceptical person has paid the price and dedicated his time to learning, he usually loses his incredulity and the self-satisfied smile of the person who cannot be taken for a ride...
Having said this, unless one is particularly sensitive and vulnerable, getting to know oneself better, or having an idea about the meteorology, is rather helpful for evolving more rapidly. So, astrology would not be useless.
This is precisely what happened to me after a few months. Then, if one does not want to stop while on such a good path, one buys books and learn... during years. To me, astrology is a tool, and not a religion or something important. It is one discipline among others, such as history or psychology. Of course, it is more helpful and somehow prompts to ask questions upstream. This is what constitutes its charm, even though in no circumstances, does it answer these questions.
Astrology is anything except a spiritual path, a religion, or a moral code. It is just a tool which enables to understand our personality, our compatibility with people, and, with caution, to forecast climates, the meteorology of our evolution.
Some people have understood that astrology worked well and prefer… to avoid predictions. However, they are very few. There is indeed the auto-suggestion issue whereby the very fear of an unfortunate event might trigger it. Although there may be some truth in it, the amount of risk is minimal.
Regarding this last point, my opinion is simple: forecasts work fine, provided that two major conditions, absolutely impossible to ignore, are met:
This recalls the nice philosophical tale of Samarkand which can be summed up as follows: a Vizier walks across the city to work at the Sultan's palace. He sees an ominous woman dressed in black, the sight of whom makes his blood curdle... As she gets nearer, he notices her glare and her expression and understands that she is Death. He is in a state of terror and thinks that she is coming to take him... more below
Regarding minor, or "average" events, caution is required. There is a "scattering" of results, as if some people were more or less sensitive to certain transits etc. There are evidences that astrology should not be thrown out the window. The effects of very important forces at play are practically always noticeable. This is something I have observed on thousands, or perhaps tens of thousands cases, and each time, it is mind blowing because it completely rules out a vision at random of the period concerned. One must experience it to believe it: it is the number of disconcerting facts, totally incompatible with coincidence, which prompts to understand that one is not wasting time with this discipline. If one remains humble enough to accept that for less important events, or forces at play, there is some degree of uncertainty, and that one deals with probabilities of more or less favourable tendencies regarding such or such point, then, one remains on the safe side.
Does it mean that astrology is deterministic and fatalistic? No, definitely. Everything unfolds as if there was a "tendency", some sort of more or less imposed, yet partial, structure. It seems that free will enables to react differently to the planetary climates undergone, and as the old saying goes, "The stars impel but do not compel". Many questions obviously arise on this subject, but the purpose of these lines is to share my practical experience, in all simplicity, without starting to give a structured explanation for each concept addressed, which would require several books.
Thus, he is terrified and starts to run like a madman to the palace, where he arrives out of breath to see the Sultan. "What's wrong with you my friend?" said the Sultan. "My Lordship, I saw Death! She came to fetch me, I am very sure... I don't want to die, I am too young, I have a family. Would you allow me to take a dozen days off and go somewhere very far because I don't want her to find me, I don't want to die!" "No problem", answered the generous and nice sultan. "You have always been loyal and reliable. Go to Samarkand, it is such a beautiful city, it will take your mind off things.
In plain words, it means that the astrological natal chart is fundamental. Predictive techniques use two charts, the natal chart, which represents our personality, our earthly self with its usual features: affectivity, intellect, capacity of action, inter-personal capacity, vitality, sexuality, behaviour, psychological facets, blockages, etc.
The Vizier sets off straight away with a few servants, a dozen camels. During four days and four nights, he hastily heads towards mythical Samarkand, fleeing the woman in black and running away from what he believes to be his fateful destiny. After four days, he eventually reaches Samarkand, a splendid city bathing in an extraordinarily beautiful light... He quickly takes a bath, changes clothes, and, without taking any rest, he gets out to have a mint tea and visit the city.
Let's take a concrete predictive case using transits for instance. One of the rules of thumb for predictions is to understand that transiting influences will fully manifest only if they are also found in the natal chart. Let's consider the difficult case of a transit of Uranus squaring natal Mars, with Mars in the 2nd House in Aries, and Uranus in the 11th House in Capricorn. These two planets are the most energetic ones, and at some time, their square triggers a blow-up in terms of behaviours or events, because the balance is too hard to maintain by the chart owner and meant to explode since the vibration does not correspond to his nature. Therefore, this explosive transit indicates that there is a probability that the financial area, or the way one earns a living, undergoes a very strong and unexpected jolt when the transit becomes exact or during Uranus' various passages as it retrogrades and squares natal Mars. This jolt may involve friends – it would be necessary to look at the rulerships. Now, there are two alternatives: if Uranus and Mars are connected in the natal chart, transiting Uranus will resonate with the natal chart, and it is most likely that important events, or the way they are felt by the chart owner, will be strongly experienced. The other alternative is that Uranus and Mars are not linked to each other in the natal chart, in which case it is clear that the effects of transiting Uranus, though violent, will have a less significant impact than in the first case.
The sun lights up the picturesque narrow streets, females are good-looking, and the shadows stretching their darker shape at this time of the afternoon increase the charm of the mythical city. The Vizier walks, deliriously happy to have escaped his fate. As he strolls and looks aside, he does not watch his steps and bumps into somebody! He immediately turns around and, to his stupefaction...
Provided these two conditions are met, i.e. some level of analogy with the natal chart, and caution whenever the influences at play are not very strong, astrology never disappoints, or almost never, as far as predictions are concerned.
Regarding couple's compatibility, there are very important rules. It is not because a synastry is exceptionally good that it means, on the one hand, that one will fall in fall, and on the other hand, that the relationship will be successful. Let me explain:
When one analyses the chart of a couple, one actually analyses three charts: the natal chart of each partner and the chart of the relationship. The latter is compared to the two natal charts and assessed using various possible techniques (composite chart, mid-space / mid-time chart, mutual planets-houses interactions, etc.). In addition of course, one must take into account the planetary climate of each partner, which is not simple.
In couple's compatibility, here are the principles that must be borne in mind:
Firstly, a fantastic compatibility between two persons never implies that they will fall in love with each other. Indeed, synastry only reflects how easy a relationship is in various areas. Conversely, a disastrous synastry does not mean that two persons will not fall in love with each other!
It is important to highlight the above because a host of visitors wonder and sometimes e-mail us asking "I met with so and so, our rate was 80% but nothing happened, the relationship has not materialised, etc.", which is normal! Astrology, at least synastry, is unable to determine whether two persons will love each other. Love eludes the comparison of charts!
Once again, if and only if, a relationship has already started, synastry will tell whether it will flow smoothly or not. In my view, that's already quite considerable!
A gorgeous and very pale lady, all dressed in black, stares at him with an almost astonished look and said, "Well, well, it's you, you are early. I did not expect you before several days yet." As she takes him by the hand, the Vizier, in a state of complete terror and at the same time strangely resigned, does not resist and follows Death, in great distress and without any possibility to rebel.
Let's imagine that this gentleman meets a lady with whom the compatibility is extraordinarily good. What would happen?
If he falls in love, and his feelings are reciprocated, the odds are that things will not develop smoothly. Actually, because the synastry is good, which is the hypothesis we have chosen, in order that his destiny unfolds according to his natal chart, certain obstacles will crop up. Such hurdles probably obey some necessity in terms of evolution etc., but this is another topic... Nevertheless, the relationship is most likely to be pleasant and easy. The rest of the context will have to be assessed: what are the active transits of the moment for both partners, what is the natal chart of the lady in question, etc.
As we can see, a relationship is a whole entity, a juxtaposition of five factors which already form a whole when taken separately: two natal charts, two forecasts or current planetary climates, and one synastry or couple report.
The analysis of these five factors is the only process which enables to understand and offer predictions about what is to follow, and even then... solely if the magical spark is born between them. Regarding the spark, let's say that transits enable to forecast whether the chart owner is likely to fall in love during the considered period.
It is true that one can try to bail out of what is deemed ineluctable, especially during loaded periods such as under Uranus' tensed transits. However, as one believes that one is escaping one's fate, one might also jump into it with one's feet together even faster!
My experience, once again with regard to this third section – since we have already addressed personality analysis and predictions – is that astrology works, provided that the natal chart is taken into account along with transits, progressions and solar revolution influences.
Which experience? It is simple. When one is interested in this tool, one quite quickly makes interpretations, thousands of charts in several years. Therefore, each time one gets the confirmation that "heavy" or major events occur according to the rules used, and that in most cases, portraits are quite accurate although of course, certain scattered charts are much more difficult to interpret than others. One also knows that humility is a must and that for lighter things, i.e. minor aspects, less important or fast transits, one really deals only with probabilities, but... that's already quite appreciable.
The last section, that of mundane forecast, is unrewarding. I will not enter into the details of the methods used, and I will only say that once again, my experience is quite a pessimistic one. Individual astrology offers results ranging from satisfactory to very satisfactory, but mundane astrology seems risky to me and, to state it clearly, not yet perfected enough.
There may be a fifth section, that of prediction of success for business companies, projects, etc. The principle is to take the exact date of creation of a project as its moment of birth and cast a chart exactly as it is done for a human being. This method can also be applied to an animal, why not.
As expounded in this article, my experience prompts me to think that there are two types of outer events: the fundamental ones, which are very rare through a lifetime, and the others. The former seem to bear some form of determinism affecting the way events unfold, because the way we experience them in our inner self is a different thing and gives our free will every latitude in making decisions, including that to grant them importance or not.
Actually, if one ponders a little bit more, for every case, the same questions apply because the exact date and time are not really significant. The same holds true also for the birth of a country, etc.
As a result, examples are not easy to study, even though they are interesting for the astrologer as a matter of curiosity. I believe that great caution is needed in this area.
Getting back to the example given at the beginning of this article, you may want to ask about the young lady, "So, was she compatible with you?" According to the analysis of the time, no! And actually, nothing happened, except in my head. Thus, astrology started to work well in those remote days despite the sadness of the conclusion.
More seriously, the purpose of these lines is to say that the irrational refusal of some people, be they scientists or not, to consider that there might be something accurate in this discipline constitutes a real sign of laughable blockages on their part.
These questions would take us too far… Nevertheless, the Samarkand tale is a classic which tends to show the limits of free will in the field of real experiences. It is important to add that, as far as death is concerned, even though there are techniques which try to determine its date, no serious astrologer will claim to be able to do so. Why? Because, and it cannot be reiterated strongly enough, astrology describes a climate and probabilities, and nothing else. I would also add that this is at the same helpful, crucial, and an excellent thing. Nothing would be worse than absolute fate and shutting the door on hope.
Here, I have talked about concrete topics and experience, and not at all about the "why". Actually, being a scientist myself, in the beginning, what I wanted to know above all was whether astrology worked.
Over 35 years of experience have answered my question although after six months or one year, I already got the answer, thus positive, just in case some visitors would directly start to read from this point on.
The topic of why it works is completely different. Here are my impressions, given in a personal capacity: at first, I would consider astrology to be a small square of life, a bit like a helpful discipline, but without –let's say, directly – spiritual connotation.
It is efficient, useful, but it offers no answer to the real questions of life, under no circumstances. What are we, what are we made of, what is Reality? Beneath thought, feelings, sensations, there is the consciousness of being, which is the only real thing, upstream. The intellect is unable to understand itself. A blind man cannot describe the colour red. Similarly, the intellect can but go round in circles when it comes to asking "who am I?", since we are not our thought and we are upstream of it or... of them, because one can rather talk about thoughts in the plural, which are like bees continuously buzzing, with an actor behind who undergoes and at the same time has the illusion of control... Of course, there is a link between these thoughts and our consciousness to exist, but... I should stop here... This is just to show that astrology answers none of these questions, that its field applies to the earthly sphere, to human psychology, to the explanation of behaviour, to the cautious forecast of the meteorology of events, and to the assessment of the smoothness, if any, of a relationship in a couple.
There is also the topic of the astrologer who analyses his future. Can he really change it? The wisest answer is that yes, one can strengthen the periods of invulnerability and thus, one's successes etc. One can also be careful and thus lessen the impact of risky periods, for practically all events.
Second reflection: we know only four forces in the universe: strong interactions (the cohesion forces of atomic nuclei), weak interactions (the cohesion forces of nuclei and particles), gravitational forces, and electro-magnetic forces. We are able neither to define the consciousness of being, nor to give a definition of thought and of ourselves. To imagine giving an answer to the whys of the functioning of astrology would require a better understanding of these two planes: the first one is that of physics, which is not as advanced as it is believed to be. The second plane is that of knowledge of human nature, which does not seem too advanced either...
The first answer is that indeed, there is no known physical explanation as of today.
There are statistics, sometimes disputed, and astrologers' experience dating back to the dawn of time – and the different schools, etc. which I have not addressed here of course – which are dismissed by detractors of astrology who are so stupidly and mechanically indoctrinated with their own certainties that they self-intoxicate themselves with their own rubbishes when... they do not act in bad faith.
Regarding major events, which can probably be counted on the fingers of the two hands throughout a lifetime, I think that the astrologer himself cannot avoid a few compulsory chapters of his destiny. This may be found disgruntling or laughable, but those who make numerous predictions are aware that it is difficult, or practically impossible, to escape very powerful configurations, be they harmonious or tricky. It should be borne in mind that what is tricky brings about awareness whereas on the contrary, what is felt as nice often yields spiritual numbness. Nothing is good, and nothing is bad; there is only a succession of tests, happy or unfortunate, and the will, or lack of, to increase one's consciousness of existing with them.
Some detractors of astrology, perhaps less obtuse than others, may imagine, during a too short-lived stroke of intuition, that not all astrologers are in a complete fog, not all malevolent, not all interested in power or money, and even that the majority do not waste their time, simply because hands-on experience has shown them the evidence, that is does work, provided due caution is observed as mentioned earlier.
Therefore, for these people, the following problem remains: "Well, let's suppose that it works and that there is some truth in it, but since there are no explanations to it, it cannot work, can it?"
A logical mind would answer back "It works of course. It is not because we don't know yet why, that it can't work, since on the contrary experience proves that it does work..."
Besides, the fact that one possesses a few assets like knowledge of astrology, or the mere fact of seeking advice from it, is part of the protections which can be found in the natal chart. The person who never doubts anything, who remains narrow-minded and keeps on his superior smile in front of concealed knowledge –astrology is not the only one – this person usually has several tensions in fixed signs in his natal chart. Indeed, fixed signs are excellent and often endow with a strong will and persuasion power, to the detriment however of open-mindedness, or rather, the swiftness to precisely adjust to whatever is new to him. Once adjustment is achieved, he will become a fierce defendant of the very cause which he fought in the first place, at least in the best cases (smile).
Astrology works although we still don't have its explanation in terms of forces. My opinion is that it will come. It constitutes an interesting subject, but not a fundamental one. The main point is to avoid talking nonsense and to be pragmatic. It seems to me that being open-minded is the only correct attitude.
Although one can live without astrology, its offers much help to those who practice it or to those who seek advice from it. It is already very appreciable. Indeed, although astrology claims neither to give an answer about the purpose of life, nor to be absolutely reliable, and in spite of the fact that the explanation of its functioning is unknown... it nevertheless delivers obvious results.
This is what justifies its practice. To my view, the only good attitudes are, either to use it with caution if it is helpful on a punctual basis or more, or to ignore it and ask "Why not, but in any case, I am not interested." The only totally ridiculous attitude is to display the self-satisfied smile of those who cannot be taken for a ride...
