Does the Past Exist Yet? Evidence Suggests Your Past Isn’t Set in Stone

By Robert Lanza 

Recent discoveries require us to rethink our understanding of history. “The histories of the universe,” said renowned physicist Stephen Hawking “depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history.”

Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future – and may even depend on actions that you haven’t taken yet.

In 2002, scientists carried out an amazing experiment, which showed that particles of light “photons” knew — in advance — what their distant twins would do in the future. They tested the communication between pairs of photons — whether to be either a wave or a particle. Researchers stretched the distance one of the photons had to take to reach its detector, so that the other photon would hit its own detector first. The photons taking this path already finished their journeys — they either collapse into a particle or don’t before their twin encounters a scrambling device.
Somehow, the particles acted on this information before it happened, and across distances instantaneously as if there was no space or time between them. They decided not to become particles before their twin ever encountered the scrambler. It doesn’t matter how we set up the experiment. Our mind and its knowledge is the only thing that determines how they behave. Experiments consistently confirm these observer-dependent effects.

More recently (Science 315, 966, 2007), scientists in France shot photons into an apparatus, and showed that what they did could retroactively change something that had already happened. As the photons passed a fork in the apparatus, they had to decide whether to behave like particles or waves when they hit a beam splitter. 
Later on – well after the photons passed the fork – the experimenter could randomly switch a second beam splitter on and off. It turns out that what the observer decided at that point, determined what the particle actually did at the fork in the past. At that moment, the experimenter chose his history.

Of course, we live in the same world. Particles have a range of possible states, and it’s not until observed that they take on properties. So until the present is determined, how can there be a past? According to visionary physicist John Wheeler (who coined the word “black hole”), “The quantum principle shows that there is a sense in which what an observer will do in the future defines what happens in the past.” Part of the past is locked in when you observe things and the “probability waves collapse.” But there’s still uncertainty, for instance, as to what’s underneath your feet. If you dig a hole, there’s a probability you’ll find a boulder. Say you hit a boulder, the glacial movements of the past that account for the rock being in exactly that spot will change as described in the Science experiment.

But what about dinosaur fossils? Fossils are really no different than anything else in nature. For instance, the carbon atoms in your body are “fossils” created in the heart of exploding supernova stars. 
Bottom line: reality begins and ends with the observer. “We are participators,” Wheeler said “in bringing about something of the universe in the distant past.” Before his death, he stated that when observing light from a quasar, we set up a quantum observation on an enormously large scale. It means, he said, the measurements made on the light now, determines the path it took billions of years ago.

Like the light from Wheeler’s quasar, historical events such as who killed JFK, might also depend on events that haven’t occurred yet. There’s enough uncertainty that it could be one person in one set of circumstances, or another person in another. Although JFK was assassinated, you only possess fragments of information about the event. But as you investigate, you collapse more and more reality. According to biocentrism, space and time are relative to the individual observer – we each carry them around like turtles with shells.

History is a biological phenomenon — it’s the logic of what you, the animal observer experiences. You have multiple possible futures, each with a different history like in the Science experiment. Consider the JFK example: say two gunmen shot at JFK, and there was an equal chance one or the other killed him. This would be a situation much like the famous Schrödinger’s cat experiment, in which the cat is both alive and dead — both possibilities exist until you open the box and investigate.

“We must re-think all that we have ever learned about the past, human evolution and the nature of reality, if we are ever to find our true place in the cosmos,” says Constance Hilliard, a historian of science at UNT. Choices you haven’t made yet might determine which of your childhood friends are still alive, or whether your dog got hit by a car yesterday. In fact, you might even collapse realities that determine whether Noah’s Ark sank. “The universe,” said John Haldane, “is not only queerer than we suppose, but queerer than we can suppose.”

This Alien Color Catalog May Help Us Spot Life on Other Planets






Excerpt from smithsonianmag.com


In the hunt for alien life, our first glimpse of extraterrestrials may be in the rainbow of colors seen coming from the surface of an exoplanet.

That's the deceptively simple idea behind a study led by Siddharth Hegde at the Max Planck Institute for Astronomy in Germany. Seen from light-years away, plants on Earth give our planet a distinctive hue in the near-infrared, a phenomenon called red edge. That's because the chlorophyll in plants absorbs most visible light waves but starts to become transparent to wavelengths on the redder end of the spectrum. An extraterrestrial looking at Earth through a telescope could match this reflected color with the presence of oxygen in our atmosphere and conclude there is life here.


exoplanets palette
Eight of the 137 microorganism samples used to measure biosignatures for the catalog of reflection signatures of Earth life forms. In each panel, the top is a regular photograph of the sample and the bottom is a micrograph, a version of the top image zoomed-in 400 times.



Plants, though, have only been around for 500 million years—a relative blip in our planet's 4.6-billion-year history. Microbes dominated the scene for some 2.5 billion years in the past, and some studies suggest they will rule the Earth again for much of its future. So Hegde and his team gathered 137 species of microorganisms that all have different pigments and that reflect light in specific ways. By building up a library of the microbes' reflectance spectra—the types of colors those microscopic critters reflect from a distance—scientists examining the light from habitable exoplanets can have a plethora of possible signals to search for, the team argues this week in the Proceedings of the National Academy of Sciences.

"No one had looked at the wide range of diverse life on Earth and asked how we could potentially spot such life on other planets, and include life from extreme environments on Earth that could be the 'norm' on other planets," Lisa Kaltenegger, a co-author on the study, says via email. "You can use it to model an Earth that is different and has different widespread biota and look how it would appear to our telescopes."

To make sure they got enough diversity, the researchers looked at temperate-dwelling microbes as well as creatures that live in extreme environments like deserts, mineral springs, hydrothermal vents or volcanically active areas.

While it might seem that alien life could take a huge variety of forms—for instance, something like the silicon-based Horta from Star Trek—it's possible to narrow things down if we restrict the search to life as we know it. First, any life-form that is carbon-based and uses water as a solvent isn't going to like the short wavelengths of light far in the ultraviolet, because this high-energy UV can damage organic molecules. At the other end of the spectrum, any molecule that alien plants (or their analogues) use to photosynthesize won't be picking up light that's too far into the infrared, because there's not enough energy at those longer wavelengths.

In addition, far-infrared light is hard to see through an Earth-like atmosphere because the gases block a lot of these waves, and whatever heat the planet emits will drown out any signal from surface life. That means the researchers restricted their library to the reflected colors we can see when looking at wavelengths in the visible part of the spectrum, the longest wavelength UV and short-wave infrared.

The library won't be much use if we can't see the planets' surfaces in the first place, and that's where the next generation of telescopes comes in, Kaltenegger says. The James Webb Space Telescope, scheduled for launch in 2018, should be able to see the spectra of relatively small exoplanet atmospheres and help scientists work out their chemical compositions, but it won't be able to see any reflected spectra from material at the surface. Luckily, there are other planned telescopes that should be able to do the job. The European Extremely Large Telescope, a 40-meter instrument in Chile, will be complete by 2022. And NASA's Wide Field Infrared Survey Telescope, which is funded and in its design stages, should be up and running by the mid-2020s.

Another issue is whether natural geologic or chemical processes could look like life and create a false signal. So far the pigments from life-forms look a lot different from those reflected by minerals, but the team hasn't examined all the possibilities either, says Kaltenegger. They hope to do more testing in the future as they build up the digital library, which is now online and free for anyone to explore at biosignatures.astro.cornell.edu.

Could Saturn’s moon Titan host an alternate type of life?


Titan


Excerpt from mashable.com

In a world first, chemical engineers have taken a different look at a question astronomers and biologists have been pondering for decades: Does Saturn moon Titan host life?

Of course, Titan is way too hostile for life as we know it to eke out an existence — it is a frigid world awash with liquid methane and ethane and a noxious atmosphere devoid of any liquid water. But say if there is a different kind of biology, a life as we don't know it, thriving on the organic chemistry that is abundant on Titan's surface?

Normally, astrobiologists combine what we know about Earth's biosphere and astronomers zoom in on other stars containing exoplanets in the hope that some of those alien world have some similarities to Earth. By looking for small rocky exoplanets orbiting inside their star's habitable zones, we are basically looking for a "second Earth" where liquid water is at least possible. Where there's liquid water on Earth, there's inevitably life, so scientists seeking out alien life 'follow the water' in the hope of finding life with a similar terrestrial template on other planets.

Titan, however, does not fall into this category, it is about as un-Earth-like as you can get. So, chemical molecular dynamics expert Paulette Clancy and James Stevenson, a graduate student in chemical engineering, from Cornell University, Ithaca, New York, have looked at Titan in a different light and created a theoretical model of a methane-based, oxygen-free life form that could thrive in that environment.

There is no known template for this kind of life on Earth, but the researchers have studied what chemicals are in abundance on Titan and worked out how a very different kind of life could be sparked.

As a collaborator on the NASA/ESA Cassini-Huygens mission, Lunine, professor in the Physical Sciences in the College of Arts and Sciences’ Department of Astronomy, has been fascinated with the possibility of methane-based life existing on Titan for some time, so he joined forces with Clancy and Stevenson to see what this hypothetical life form might look like.

In their research published in the journal Science Advances on Feb. 27, Clancy and Stevenson focused on building a cell membrane "composed of small organic nitrogen compounds and capable of functioning in liquid methane temperatures of 292 degrees below zero (Fahrenheit; or 94 Kelvin)," writes a Cornell press release. On Earth, water-based molecules form phospholipid bilayer membranes that give cells structure, housing organic materials inside while remaining permeable. On Titan, liquid water isn't available to build these cell membranes.

"We're not biologists, and we're not astronomers, but we had the right tools," said Clancy, lead researcher of the study. "Perhaps it helped, because we didn't come in with any preconceptions about what should be in a membrane and what shouldn't. We just worked with the compounds that we knew were there and asked, 'If this was your palette, what can you make out of that?'"

The researchers were able to model the ideal cell that can do all the things that life can do (i.e. support metabolism and reproduction), but constructed it from nitrogen, carbon and hydrogen-based molecules that are known to exist in Titan's liquid methane seas. This chemical configuration gives this theoretical alien cell stability and flexibility in a similar manner to Earth life cells.
"The engineers named their theorized cell membrane an 'azotosome,' 'azote' being the French word for nitrogen. 'Liposome' comes from the Greek 'lipos' and 'soma' to mean 'lipid body;' by analogy, 'azotosome' means 'nitrogen body.'" — Cornell
"Ours is the first concrete blueprint of life not as we know it," said lead author Stevenson, who also said that he was inspired, in part, by Isaac Asimov, who wrote the 1962 essay "Not as We Know It" about non-water-based life.

Having identified a possible type of cell membrane chemistry that functions in the Titan environment as a cell on Earth might, the next step is to model how such a hypothetical type of biology would function on Titan. In the long run, we might also be able to model what kinds of observable indicators we should look for that might reveal that alien biology's presence.

That way, should a mission be eventually sent to Titan's seas, sampling the chemical compounds in the soup of organics may reveal a biology of a very alien nature.
Scientists have been trying to know if life could exist on Titan, the largest moon of Saturn. According to scientists, there are possibilities that life could survive amidst methane-based lakes of Titan. After conducting many studies, they have found signs of life on Titan, but the scientists also said that life will not be like life on earth.
As per some scientific reports, Titan is the only object other than earth which has clear evidence of stable bodies of surface liquid. Like earth, the moon has mountains, islands, lakes and storms, but it doesn’t have oxygen, which is a major element to support life. It means that only oxygen-free and methane-based can exist on Titan.
According to lead researcher Paulette Clancy, “We didn’t come in with any preconceptions about what should be in a membrane and what shouldn’t. We just worked with the compounds that, we knew were there and asked, ‘If this was your palette, what can you make out of that”.
Clancy said although they are not biologists or astronomers, they had the right tools to find life on Saturn’s largest moon. Adding to that, the researchers didn’t know what should be in a membrane and what should be not. They worked with compounds and found that life can exist on Titan, but would be very different from earth’s life, Clancy added.
According to reports, the researchers had used a molecular dynamics method to know about Titan. They screened for suitable candidate compounds from methane for self-assembly into membrane-like structures. As per the researchers, the most promising compound they discovered was an acrylonitrile azotosome, which is present in the atmosphere of Titan.
As per the researchers, acrylonitrile has shown good stability and flexibility similar to that of phospholipid membranes on Earth. It means that the Saturn largest has atmosphere and conditions to support life in a different way than earth.

A Major Victory for the Open Web

Excerpt from blog.mozilla.org
We just accomplished something very important together. Today, the U.S. Federal Communications Commission voted for strong net neutrality protections. This happened because millions of people — including many hundreds of thousands in Mozilla’s community — joined together as citizens of the Web to demand those strong protections.


This is an important victory for the world’s largest public resource, the open Web. Net neutrality is a key aspect of enabling innovation from everywhere, and especially from new players and unexpected places. Net neutrality allows citizens and consumers to access new innovations and judge the merit for themselves. It allows individual citizens to make decisions, without gate-keepers who decide which possibilities can become real. Today’s net neutrality rules help us protect this open and innovative potential of the Internet.

Mozilla builds our products to put this openness and opportunity into the hands of individuals. We are organized as a non-profit so that the assets we create benefit everyone. Our products go hand-in-hand with net neutrality; they need net neutrality to bring the full potential of the Internet to all of us.

Today’s net neutrality rules are an important step in protecting opportunity for all. This victory was not inevitable. It occurred because so many people took action, so many people put their voice into the process. To each of you we say “Thank you.” Thank you for taking the time to understand the issue, for recognizing it’s important, and for taking action. Thank you for helping us build openness and opportunity into the very fabric of the Internet.

Google’s AI Program Is Better At Video Games Than You





pcmag.com

IBM's Watson supercomputer may be saving lives and educating children, but Google's new AI program can master video games without human guidance.

The artificial intelligence system from London-based DeepMind, which Google acquired last year for a reported $400 million, represents a major step toward a future of smart machines.

Computers running the deep Q-network (DQN) algorithm were exposed to 49 retro games on the Atari 2600 and told to play them, without any direction from researchers. Using the same network architecture and tuning parameters, the machines were given only raw screen pixels, available actions, and game score as input.

For each level passed or high score earned, the computer was automatically rewarded with a digital treat.

"Strikingly, DQN was able to work straight 'out of the box' across all these games," DeepMind's Dharshan Kumaran and Demis Hassabis wrote in a blog post. The executives cited classic titles like Breakout, River Raid, Boxing, and Enduro.

The AI crushed even the most expert humans at 29 games, sometimes composing what the creators called "surprisingly far-sighted strategies" that allowed maximum scoring possibilities. It also outperformed previous machine-learning methods in 43 of 49 instances.

VIEW ALL PHOTOS IN GALLERY
Google DeepMind's findings were presented in a paper published in this week's Nature journal, which describes the key DQN features that allow it to learn.

"This work offers the first demonstration of a general purpose learning agent that can be trained end-to-end to handle a wide variety of challenging tasks," the researchers said. "This kind of technology should help us build more useful products."

Imagine asking the Google app to complete a complex task—like plan a backpacking trip through Europe, for example.

Google's DeepMind also hopes its technology will give researchers new ways to make sense of large-scale data, opening the door to discoveries in fields like climate science, physics, medicine, and genomics.

"And it may even help scientists better understand the process by which humans learn," Kumaran and Hassabis said, citing physicist Richard Feynman, who famously said, "What I cannot create, I do not understand."

A ‘bionic leaf’ that turns sunlight into fuel


Excerpt from cnbc.com

By Robert Ferris



The invention could pave the way for numerous innovations—by converting solar power into biofuels, it may help solve the vexing difficulty of storing unused solar energy, which is one of the most common criticisms of solar power as a viable energy source.
The process could also help make plastics and other chemicals and substances useful to industry and research.


The current experiment builds on previous research led by Harvard engineer Daniel Nocera, who in 2011 demonstrated an "artificial leaf" device that uses solar power to generate usable energy. 

Nocera's original invention was a wafer-like electrode suspended in water. When a current runs through the electrode from a power source such as a solar panel, for example, it causes the water to break down into its two components: hydrogen and oxygen. 

Nocera's device garnered a lot of attention for opening up the possibility of using sunlight to create hydrogen fuel—once considered a possible alternative to gasoline. 

But hydrogen has not taken off as a fuel source, even as other alternative energy sources survive and grow amid historically low oil prices. Hydrogen is expensive to transport, and the costs of adopting and distributing hydrogen are high. A gas station owner could more easily switch a pump from gasoline to biofuel, for example.


Now, Nocera and a team of Harvard researchers figured out how to use the bionic leaf to make a burnable biofuel, according to a study published Monday in the journal PNAS. The biologists on the team genetically modified a strain of bacteria that consumes hydrogen and produces isopropanol—the active ingredient in rubbing alcohol. In doing so, they successfully mimicked the natural process of photosynthesis—the way plants use energy from the sun to survive and grow.

This makes two things possible that have always been serious challenges for alternative energy space—solar energy can be converted into a storable form of energy, and the hydrogen can generate a more easily used fuel.


To be sure, the bionic leaf developments are highly unlikely to replace fossil fuels such as oil and natural gas any time soon—especially as the prices of both are currently so low. But it could be a good supplemental source. 

"One idea Dan [Nocera] and I share, which might seem a little wacky, is personalized energy" that doesn't rely on the power grid, biochemist Pamela Silver, who participated in the study, told CNBC in a telephone interview. 


Typically, people's energy needs are met by central energy production facilities—they get their electricity from the power grid, which is fed by coal- or gas-burning power plants, or solar farms, for example. Silver said locally produced energy could be feasible in developing countries that lack stable energy infrastructure, or could even appeal to people who choose to live off the grid.

"Instead of having to buy and store fuel, you can have your bucket of bacteria in your backyard," Silver said. 

Besides, the experiment was an attempt at proof-of-concept—the scientists wanted to demonstrate what could be done, Silver said. Now that they have mastered this process, further possibilities can be explored.  

"No insult to chemists, but biology is the best chemist there is, so we don't even know what we can make," said Silver. "We can make drugs, materials—we are just at the tip of the iceberg." 

The team hopes to develop many different kinds of bacteria that can produce all sorts of substances. That would mean, potentially at least, setting up the bionic leaf device and then plugging in whatever kind of bacteria might be needed at the moment.

For now, they want to increase the efficiency of the device, which is already much more efficient at photosynthesizing than plants are. Then they will focus on developing other kinds of bacteria to plug into the device.

"The uber goal, which is probably 20 years out," Silver said, "is converting the commodity industry away from petroleum."

How Would the World Change If We Found Alien Life?







Excerpt from space.com
By by Elizabeth Howell

In 1938, Orson Welles narrated a radio broadcast of "War of the Worlds" as a series of simulated radio bulletins of what was happening in real time as Martians arrived on our home planet. The broadcast is widely remembered for creating public panic, although to what extent is hotly debated today.

Still, the incident serves as an illustration of what could happen when the first life beyond Earth is discovered. While scientists might be excited by the prospect, introducing the public, politicians and interest groups to the idea could take some time.

How extraterrestrial life would change our world view is a research interest of Steven Dick, who just completed a term as the Baruch S. Blumberg NASA/Library of Congress Chair of Astrobiology. The chair is jointly sponsored by the NASA Astrobiology Program and the John W. Kluge Center, at the Library of Congress. 


Dick is a former astronomer and historian at the United States Naval Observatory, a past chief historian for NASA, and has published several books concerning the discovery of life beyond Earth. To Dick, even the discovery of microbes would be a profound shift for science.

"If we found microbes, it would have an effect on science, especially biology, by universalizing biology," he said. "We only have one case of biology on Earth. It's all related. It's all DNA-based. If we found an independent example on Mars or Europa, we have a chance of forming a universal biology."

Dick points out that even the possibilities of extraterrestrial fossils could change our viewpoints, such as the ongoing discussion of ALH84001, a Martian meteorite found in Antarctica that erupted into public consciousness in 1996 after a Science article said structures inside of it could be linked to biological activity. The conclusion, which is still debated today, led to congressional hearings.

"I've done a book about discovery in astronomy, and it's an extended process," Dick pointed out. "It's not like you point your telescope and say, 'Oh, I made a discovery.' It's always an extended process: You have to detect something, you have to interpret it, and it takes a long time to understand it. As for extraterrestrial life, the Mars rock showed it could take an extended period of years to understand it."


ALH84001 Meteorite
The ALH84001 meteorite, which in a 1996 Science publication was speculated to be host to what could be ancient Martian fossils. That finding is still under dispute today.

Mayan decipherments

In his year at the Library of Congress, Dick spent time searching for historical examples (as well as historical analogies) of how humanity might deal with first contact with an extraterrestrial civilization. History shows that contact with new cultures can go in vastly different directions.

Hernan Cortes' treatment of the Aztecs is often cited as an example of how wrong first contact can go. But there were other efforts that were a little more mutually beneficial, although the outcomes were never perfect. Fur traders in Canada in the 1800s worked closely with Native Americans, for example, and the Chinese treasure fleet of the 15th Century successfully brought its home culture far beyond its borders, perhaps even to East Africa.

Even when both sides were trying hard to make communication work, there were barriers, noted Dick.

"The Jesuits had contact with Native Americans," he pointed out. "Certain concepts were difficult, like when they tried to get across the ideas of the soul and immortality."



A second look by the Mars Global Surveyor at the so-called Viking “Face on Mars” in Cydonia revealed a more ordinary-looking hill, showing that science is an extended process of discovery.


Indirect contact by way of radio communications through the Search for Extraterrestrial Intelligence (SETI), also illustrates the challenges of transmitting information across cultures. There is historical precedence for this, such as when Greek knowledge passed west through Arab translators in the 12th Century. This shows that it is possible for ideas to be revived, even from dead cultures, he said.

It's also quite possible that the language we receive across these indirect communications would be foreign to us. Even though mathematics is often cited as a universal language, Dick said there are actually two schools of thought. One theory is that there is, indeed, one kind of mathematics that is based on a Platonic idea, and the other theory is that mathematics is a construction of the culture that you are in. 

"There will be a decipherment process. It might be more like the Mayan decipherments," Dick said.


The ethics of contact

As Dick came to a greater understanding about the potential c impact of extraterrestrial intelligence, he invited other scholars to present their findings along with him. Dick chaired a two-day NASA/Library of Congress Astrobiology Symposium called "Preparing for Discovery," which was intended to address the impact of finding any kind of life beyond Earth, whether microbial or some kind of intelligent, multicellular life form.

The symposium participants discussed how to move beyond human-centered views of defining life, how to understand the philosophical and theological problems a discovery would bring, and how to help the public understand the implications of a discovery.

"There is also the question of what I call astro-ethics," Dick said. "How do you treat alien life? How do you treat it differently, ranging from microbes to intelligence? So we had a philosopher at our symposium talking about the moral status of non-human organisms, talking in relation to animals on Earth and what their status is in relation to us."

Dick plans to collect the lectures in a book for publication next year, but he also spent his time at the library gathering materials for a second book about how discovering life beyond Earth will revolutionize our thinking.

"It's very farsighted for NASA to fund a position like this," Dick added. "They have all their programs in astrobiology, they fund the scientists, but here they fund somebody to think about what the implications might be. It's a good idea to do this, to foresee what might happen before it occurs."

6 Supermaterials That Could Change Our World


Graphene

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

6 Supermaterials That Could Change Our World

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

6 Supermaterials That Could Change Our World

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

6 Supermaterials That Could Change Our World

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

6 Supermaterials That Could Change Our World 
The molecular structure of stanene. Image credit: SLAC


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]

Pittsburg Company To Take Mementos To Moon





pittsburgh.cbslocal.com

Astrobotic Technology Inc. announced the launch of their Moon Mail program, which will send a small memento to the moon for you on its Griffin lunar lander.

“For the first time ever, people from all over the world can take their keepsakes, mementos, and fly them all the way directly to the moon,” John Thornton told KDKA money editor Jon Delano on Thursday.

The company was found in 2008 and is a licensed contractor with NASA. They are also an official partner with NASA on the Lunar CATALYST program.

According to a press release, the program is, “an opportunity to commemorate major life events – graduations, weddings, birthdays, a loved one’s memory – with a lasting symbol on the moon.”
“With Moon Mail, people from around the world can send a memento on Astrobotic’s lunar lander,” Astrobotic CEO John Thornton said in a statement. “They’ll make history by participating in the first commercial Moon landing.”

“We’re a delivery service. We’re just like FedEx or UPS. We take your packages and send them to the moon,” Thornton said.
Looking for a cool Christmas gift for a loved one?
Thornton says, send a memory of them to the moon.

“The moon is a forever place. It’s up in the sky and you can see it every single night, so we can send pieces of ourselves, stories, and mementos that mean something to us as individuals, and it will be forever immortalized on the surface of the moon.”

In about two years, Astrobotic will launch its first space craft to the moon as part of Google’s Lunar X-Prize Contest — and then land on the surface.

The lunar lander looks pretty typical, and mail will be strapped or attached right to the surface of the lander. The lander ends up on the moon where it stays forever along with your package.

It’s not cheap.

Depending on the size of your package, the price ranges from $460 to over $25,000.

“Wouldn’t interest me in the least,” says Carolyn Roberts of Murraysville.

“I want to keep everything here. Give it to the kids,” adds Daneen Miller of Murraysville.

While some have no interest, others see the possibilities.
“It would be pretty cool to say you had a piece of yourself on the moon,” notes R. J. Baughman of Robinson.

“Something that means a lot to me I guess,” says Nikki Boyle of Castle Shannon. “That way if I look up at the moon, I know it’s there.

A pretty cool thought indeed.

The Astonishing Sumerian Kings List ~ Did Sumerian Kings Rule for Thousands of Years? By Greg Giles


https://i0.wp.com/sumerianshakespeare.com/media/eff4fb62c807457effff8059ffffe417.jpg?resize=640%2C340
All four sides of the Sumerian kings list artifact

The following work is a translation provided by Oxford University (England), of a prism now in the Weld-Blundell collection of the Ashmolean Museum in Oxford, England. Known more popularly as the Sumerian kings list, it is a list compiled from fifteen or more different texts, tracing the rulers of certain Sumerian cities in succession. The original form of the list is believed to go back to approximately 2,000 BC.  


What is remarkable about this list is the lengths of reigns of a number of kings, some listed as long as 43,200 years. I find several possibilities for the long reigns inscribed on this artifact.  

1. This artifact is a hoax. I do not see this as likely however, as this artifact appears to be taken seriously by credible sources, namely Oxford University.  

2. The scribes and artisans who created the list erred. I do not see this as a very likely explanation either, as even the most mathematically challenged scribe would have noticed the hugely obvious oversights.  

3. The lengths of reigns was propaganda, conning the masses into seeing their kings as more god-like. This scenario is at least plausible, as history books state that as recently as the 20th century, the Japanese people believed their emperor Hirohito was a god, only to be shocked to learn the truth as he made public appearances after Japan's defeat at the end of World War 2. 

4. A handful of modern day scholars believe the years listed are multiplied equations, with kings receiving exaggerated lengths of reigns dependent upon their achievements while ruler. I see this as possible, though I am not convinced. Why choose such an odd way to honor a past king? Sumerians have preserved in tablet and other forms such accurate record keeping on so many varied subjects. Would they really choose to distort their records, records they carefully preserved for future generations, to honor past kings? There is also a lack of solid evidence to support this theory. 

5. Humans lived far longer life spans in our past. I see this theory as certainly possible.  

6. Ancient Sumerian kings were of extraterrestrial origin. 

What I find most intriguing is that possibilities number 5 & 6 appear the most likely explanations to the Sumerian king list.

Ramblings of an Insomniac Sagittarius ~ Virtual Reality & the Light at the End of the Tunnel ~ By Greg Giles





Ramblings of an Insomniac Sagittarius


So what's keeping me up tonight?


Well, it's this light; you know the one, the bright light at the end of the tunnel that so many report after a near-death experience. I think about that light a lot, and it's no wonder really as, although our world is full of countless mysteries, there aren’t too many that are as incredible to think about then the question of life after death. One of my favorite pastimes is to try to picture just what it is exactly that awaits us at the end of our current lives, and at the end of that lighted tunnel. 


Firstly, let's take a cursory look at the odds that there is something for us after this lifetime. At minimum it's a 50-50 shot, as either there is something after here or there isn't. But we can go beyond that and adjust those odds a bit by adding variables to our equation.

Let's consider the countless reports of an afterlife witnessed during a near-death experience. If just one of these reports is accurate-just one mind you, then the odds that something awaits us after this lifetime shifts dramatically, wouldn't you say?


Aside from that, we can add as a variable the incredible long shots necessary for life as we know it to come into being. These long shots certainly shift our odds considerably, and I must say it’s quite refreshing and enjoyable to stand on the short-shot side for once.

Another piece of evidence we would be remiss not to examine is a piece of evidence that is certainly the largest and for me, the most obvious, yet I believe it is the single piece of evidence that is more commonly overlooked when examining the life after death question; our visible universe itself. Just think about it for a moment; does this incredible, remarkable, miraculous, gorgeous, mysterious and seemingly boundless kingdom resemble in any way an accident? Or does it resemble more a product of conscious and purposeful creation? 


When I look around, especially when I look up, I am left with absolutely no doubt that all and everything is a product of intelligent design. So for me, the odds are astoundingly good there awaits us something incredible, something miraculous, and for me, something so exciting to think about. I think a lot of us may lose sight of that sometimes.


So, what is it then that awaits us? Let's start off with what is, for me, but perhaps not you, the most hellish possibility. If the bright light at the end of the tunnel is a hospital delivery room and we are immediately born right back into this world, well then, I would have to say that all those biblical stories about hell are true. 


But moving on to more positive possibilities of the white light at the end of the tunnel, I feel a very good possibility would be that the white light that we are seeing is actually our eyes filling with light as we remove a virtual reality headset. You may feel that this is kind of an odd possibility, but I feel it is a very real possible that all of us are playing an Earth-sized virtual reality game, an MMORPG, or massively multiplayer online role-playing game, not unlike World of Warcraft. 
Playing World of Warcraft



Can you imagine that? Just imagine, at the end of your life here, you experience the sensation of someone somewhere helping you pull from your head a virtual reality headset as your eyes fill with the bright light of a room, possibly even your very own bedroom, somewhere, sometime. Where could that possibly be, and what can our reallives possibly be like?  


Just think about for a moment. If our lives are constructs of a super advanced virtual reality game, just imagine what our genuine reality could be like. It could be absolutely unidentifiable to the lives we are now living. We could be living eternal and incredible lives humans currently reserve only for gods. Wouldn't that be wonderful? Wouldn't that be miraculous? And I see all this as a very plausible possibility. I even see this possibility as the most plausible, as amazing as that may seem.  


Now, if we are currently living a reality that is completely removed from our true reality, then how would we have entered this virtual state? We must enter it somehow, and we aren’t getting hit over the head with a brick like in an Ignatz and Krazy Kat cartoon. No, there must be some kind of process we go through to enter this state of reality, and I feel it’s likely we utilize some kind of virtual reality technology, even if that technology is largely natural, meaning we utilize our minds more than we rely on technology. Nonetheless, I believe that we are using some kind of virtual reality to enter this reality, this MMORPG. 

Ignatz & Krazy Kat ~ Probably one of the reasons we are playing this virtual reality game


Just sitting here at the computer sharing my thoughts about this with you causes my mind to stir, and I see I’m going to be up very late tonight as I lie in bed pondering all of this, but I can't think of a better reason to miss a little sleep.

Saturn’s ‘Death Star’ moon could harbor a secret ocean

Mimas, Saturn's 'Death Star' moon

When it comes to Saturn’s moons, water-squirting Enceladus and the hydrocarbon lakes of Titan typically steal the spotlight. But now, scientists think that lesser-known Mimas may be harboring a strange secret of its own. Scientists who studied the ‘Death Star’ moon with NASA’S Cassini spacecraft have discovered a weird wobble in its motions that could mean one of two things: Either Mimas has an oddly elongated core, or it’s hiding an ocean inside its icy body.
The findings, described in the journal Science, shed new light on a mysterious but often-overlooked moon that could hold clues to its early formation.

Mimas is an icy moon that’s 246 miles wide and whose most distinctive feature is the 88-mile-wide Herschel crater – a giant Cyclops-like indentation that makes the moon resemble the planet-obliterating superweapon from "Star Wars" that's known as the Death Star.
But the scientists noticed something strange – the moon seemed to be wobbling, or “librating,” about twice as much as they expected. After going through several different explanations, they settled on two main possibilities. Either this round moon has a football-shaped core that’s causing the wobble, or there’s a liquid water ocean underneath the icy surface.
If Mimas holds an ocean, it joins an elite group of moons (including Enceladus as well as Jupiter's moon Europa) that potentially hold liquid water – which is key for the search for other worlds besides Earth with life-hosting potential.
