What happens when you point a telescope for black holes at the sun?

The first image of the sun captured by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which is sensitive to high-energy X-ray light. X-rays seen by NuSTAR show up as green and blue in the photo, which is overlaid on an image taken by NASA's Solar Dynamics Observatory.

A NASA space telescope designed to peer at faraway black holes has snapped a stunning image of the sun, showing that its sensitive X-ray eyes can investigate mysteries in Earth's own neighborhood.
The new image, which was taken by NASA's NuSTAR spacecraft (short for Nuclear Spectroscopic Telescope Array), is the best-ever view of the sun in high-energy X-ray light, space agency officials said. The photo, and others taken by NuSTAR in the future, should help researchers learn more about our star, they added.

"NuSTAR will give us a unique look at the sun, from the deepest to the highest parts of its atmosphere," NuSTAR team member David Smith, of the University of California, Santa Cruz, said in a statement. 

The new image, which was released Monday (Dec. 22), overlays NuSTAR observations (seen in blue and green) onto an image of the sun captured by NASA's Solar Dynamics Observatory spacecraft.

NuSTAR solar observations might also reveal more about the nature of dark matter, the mysterious stuff thought to make up most of the material universe.

Dark matter apparently does not emit or absorb light — hence its name — and nobody knows for sure what it's made of. A number of exotic particles have been proposed as dark matter constituents, including weakly interacting massive particles, sterile neutrinos and axions.

If axions exist, NuSTAR may see signs of them — patches of X-rays in the center of the sun — NASA officials said.

How will the world end? From ‘demonic’ AI to nuclear war — seven scenarios that could end human race




news.nationalpost.com 


Humanity may have already created its own nemesis, Professor Stephen Hawking warned last week. The Cambridge University physicist claimed that new developments in the field of artificial intelligence (AI) mean that within a few decades, computers thousands of times more powerful than in existence today may decide to usurp their creators and effectively end humanity’s 100,000-year dominance of Earth.
This Terminator scenario is taken seriously by many scientists and technologists. Before Prof. Hawking made his remarks, Elon Musk, the genius behind the Tesla electric car and PayPal, had stated that “with artificial intelligence, we are summoning the demon,” comparing it unfavourably with nuclear war as the most potent threat to humanity’s existence.
Aside from the rise of the machines, many potential threats have been identified to our species, our civilization, even our planet. To keep you awake at night, here are seven of the most plausible.

1. ASTEROID STRIKE
Our solar system is littered with billions of pieces of debris, from the size of large boulders to objects hundreds of kilometres across. We know that, from time to time, these hit the Earth. Sixty-five-million years ago, an object – possibly a comet a few times larger than the one on which the Philae probe landed last month – hit the Mexican coast and triggered a global winter that wiped out the dinosaurs. In 1908, a smaller object hit a remote part of Siberia and devastated hundreds of square kilometres of forest. Last week, 100 scientists, including Lord Rees of Ludlow, the Astronomer Royal, called for the creation of a global warning system to alert us if a killer rock is on the way.
Probability: remote in our lifetime, but one day we will be hit.
Result: there has been no strike big enough to wipe out all life on Earth – an “extinction-level event” – for at least three billion years. But a dino-killer would certainly be the end of our civilization and possibly our species.

Warner Bros.When artificial intelligence becomes self-aware, there is a chance it will look something like this scene from Terminator 3.
2. ARTIFICIAL INTELLIGENCE
Prof. Hawking is not worried about armies of autonomous drones taking over the world, but something more subtle – and more sinister. Some technologists believe that an event they call the Singularity is only a few decades away. This is a point at which the combined networked computing power of the world’s AI systems begins a massive, runaway increase in capability – an explosion in machine intelligence. By then, we will probably have handed over control to most of our vital systems, from food distribution networks to power plants, sewage and water treatment works, and the global banking system. The machines could bring us to our knees without a shot being fired. And we cannot simply pull the plug, because they control the power supplies.

Probability: unknown, although computing power is doubling every 18 months. We do not know if machines can be conscious or “want” to do anything, and sceptics point out that the cleverest computers in existence are currently no brighter than cockroaches.
Result: if the web wakes up and wants to sweep us aside, we may have a fight on our hands (perhaps even something similar to the man vs. machines battle in the Terminator films). But it is unlikely that the machines will want to destroy the planet – they “live” here, too.

3. A GENETICALLY CREATED PLAGUE
This is possibly the most terrifying short-term threat because it is so plausible. The reason Ebola has not become a worldwide plague – and will not do so – is because it is so hard to transmit, and because it incapacitates and kills its victims so quickly. However, a modified version of the disease that can be transmitted through the air, or which allows its host to travel around for weeks, symptom-free, could kill many millions. It is unknown whether any terror group has the knowledge or facilities to do something like this, but it is chilling to realize that the main reason we understand Ebola so well is that its potential to be weaponized was quickly realized by defence experts.
Probability: someone will probably try it one day.
Result: potentially catastrophic. “Ordinary” infectious diseases such as avian-flu strains have the capability to wipe out hundreds of millions of people.

4. NUCLEAR WAR
This is still the most plausible “doomsday” scenario. Despite arms-limitations treaties, there are more than 15,000 nuclear warheads and bombs in existence – many more, in theory, than would be required to kill every human on Earth. Even a small nuclear war has the potential to cause widespread devastation. In 2011, a study by NASA scientists concluded that a limited atomic war between India and Pakistan involving just 100 Hiroshima-sized detonations would throw enough dust into the air to cause temperatures to drop more than 1.2C globally for a decade.
Probability: high. Nine states have nuclear weapons, and more want to join the club. The nuclear wannabes are not paragons of democracy.
Result: it is unlikely that even a global nuclear war between Russia and NATO would wipe us all out, but it would kill billions and wreck the world economy for a century. A regional war, we now know, could have effects far beyond the borders of the conflict.
CERN)/MCT
CERN)/MCTThis is one of the huge particle detectors in the Large Hadron Collider, a 17 mile-long tunnel under the French-Swiss border. Scientists are searching for evidence of what happened right after- and perhaps before- the Big Bang.
5. PARTICLE ACCELERATOR DISASTER
Before the Large Hadron Collider (LHC), the massive machine at CERN in Switzerland that detected the Higgs boson a couple of years ago, was switched on, there was a legal challenge from a German scientist called Otto Rossler, who claimed the atom-smasher could theoretically create a small black hole by mistake – which would then go on to eat the Earth.
The claim was absurd: the collisions in the LHC are far less energetic than those caused naturally by cosmic rays hitting the planet. But it is possible that, one day, a souped-up version of the LHC could create something that destroys the Earth – or even the universe – at the speed of light.
Probability: very low indeed.
Result: potentially devastating, but don’t bother cancelling the house insurance just yet.

6. ‘GOD’ REACHES FOR THE OFF-SWITCH
Many scientists have pointed out that there is something fishy about our universe. The physical constants – the numbers governing the fundamental forces and masses of nature – seem fine-tuned to allow life of some form to exist. The great physicist Sir Fred Hoyle once wondered if the universe might be a “put-up job”.
More recently, the Oxford University philosopher Nick Bostrom has speculated that our universe may be one of countless “simulations” running in some alien computer, much like a computer game. If so, we have to hope that the beings behind our fake universe are benign – and do not reach for the off-button should we start misbehaving.
Probability: according to Professor Bostrom’s calculations, if certain assumptions are made, there is a greater than 50% chance that our universe is not real. And the increasingly puzzling absence of any evidence of alien life may be indirect evidence that the universe is not what it seems.
Result: catastrophic, if the gamers turn against us. The only consolation is the knowledge that there is absolutely nothing we can do about it.

Global warming is rapidly turning America the beautiful into America the stormy and dangerous, according to the National Climate Assessment report released Tuesday, May 6, 2014.
7. CLIMATE CATASTROPHE
Almost no serious scientists now doubt that human carbon emissions are having an effect on the planet’s climate. The latest report by the Intergovernmental Panel on Climate Change suggested that containing temperature rises to below 2C above the pre-industrial average is now unlikely, and that we face a future three or four degrees warmer than today.
This will not literally be the end of the world – but humanity will need all the resources at its disposal to cope with such a dramatic shift. Unfortunately, the effects of climate change will really start to kick in just at the point when the human population is expected to peak – at about nine billion by the middle of this century. Millions of people, mostly poor, face losing their homes to sea-level rises (by up to a metre or more by 2100) and shifting weather patterns may disrupt agriculture dramatically.
Probability: it is now almost certain that CO2 levels will keep rising to 600 parts per billion and beyond. It is equally certain that the climate will respond accordingly.
Result: catastrophic in some places, less so in others (including northern Europe, where temperature rises will be moderated by the Atlantic). The good news is that, unlike with most of the disasters here, we have a chance to do something about climate change now.

It’s Alive! NASA’s New Horizons Pluto Probe ‘Wakes Up’ for Work


View image on Twitter


Excerpt from nbcnews.com
By Alan Boyle
The first signals were received at the mission's control center at Johns Hopkins University's Applied Physics Laboratory in Maryland via a giant radio antenna in Australia just before 9:30 p.m. ET, nearly four and a half hours after it was sent by the piano-sized probe. It takes that long for signals to travel between there and here at the speed of light. 

Later readings confirmed that New Horizons was fully awake.
New Horizons has been spending about two-thirds of the time since its launch in 2006 in hibernation, to save on electronic wear and tear as well as operational costs. Every few months, the spacecraft's systems have been roused to wakefulness for a checkup, or for photo ops such as its Jupiter flyby in 2007. 

The probe also has been sending weekly blips known as "green beacons" — to let the mission team know it's not dead, but only sleeping. 

From now on, New Horizons will remain awake continuously through its Bastille Day flyby of Pluto and its moons next July 14. After a few weeks of preparation, the probe's instruments will start making long-range observations on Jan. 15. 

The spacecraft is currently about 162 million miles away from Pluto, but as that distance shrinks, the observations will get better and better. By next May, New Horizons' images of Pluto should be sharper than the best pictures taken by the Hubble Space Telescope. And in July, the probe may catch sight of the clouds and ice volcanoes that scientists suspect may exist on the dwarf planet.

Scientists Unveiled the History of Human Alcohol Consumption




Excerpt from
rt.com 

Civilization has been enjoying a good tipple for much longer than we previously thought, according to a new study. In fact, it seems that our primate ancestors began getting tipsy 10 million years ago, by eating and metabolizing fermented fruit.

Until now, it was widely believed that man came into contact with alcohol around 9,000 years ago, when Chinese villagers combined fruit and honey to make an intoxicating brew.

But a new study in the Proceedings of the National Academy of Sciences claims that humankind has been boozing for much longer than believed. 

Research led by Professor Matthew Carrigan from Santa Fe College in Florida, examined the alcohol gene ADH4, “the first enzyme exposed to ethanol in the digestive tract that is capable of metabolizing ethanol,” in samples of almost 70 million years of primate evolution. Scientists were able to identify a single gene variant that enabled our kind to first break down ethanol in the digestive system – and it took place about 10 million years ago.

“The evolving catalytic properties of these resurrected enzymes show that our ape ancestors gained a digestive dehydrogenase enzyme capable of metabolizing ethanol near the time they began using the forest floor about 10 million years ago,” Professor Carrigan said, as quoted by the Mirror.
The study of the ADH4 family was reconstructed using genes from 28 different mammals, including 17 primates from public databases or DNA extracted from tissue samples.
The research found that hominins – early humans – were able to metabolise ethanol long before “human-directed fermentation.” The mutation coincided with the transition to a “terrestrial lifestyle,” when our ancestors were forced to come down from a tree and eat fermented fruits during times of food scarcity.
As fruit on ground contains higher concentrations of fermenting yeast and ethanol than fruits hanging on trees, “this transition may also be the first time our ancestors were exposed to - and adapted to - substantial amounts of dietary ethanol,” Professor Carrigan said. 

“The ADH4 enzyme in our more ancient and arboreal ancestors did not efficiently oxidize ethanol. This change suggests exposure to dietary sources of ethanol increased in hominids during the early stages of our adaptation to a terrestrial lifestyle,” he added.
This transition, Carrigan concludes, “implies the genomes of modern human, chimpanzee and gorilla began adapting...to dietary ethanol...that is remarkably similar in concentration and form...to the moderate ethanol consumption now recognised to be healthy for many humans.”

Elusive dark matter may be detected with GPS satellites

Global Positioning System, or GPS for short, devices are typically used for navigation purposes. But this satellite network could also alert us to something else: the presence of dark matter.

Dark matter is thought to form 80% of the universe, but is difficult to detect because it rarely interacts with ordinary matter. Its makeup is unknown, as it has never been viewed by science. Some have suggested that dark matter is a particle; however, a new study indicates that dark matter may consist of kinks in the quantum field.

According to Andrei Derevianko at the University of Nevada, Reno, and Maxim Pospelov at the Perimeter Institute in Waterloo, Ontario, Canada, dark matter may be made of quantum field cracks that can be detected by GPS. The theory is a revolutionary one, and would change the nature of time and space where the kinds are located.

One of these elements is time, which is tracked by the extremely accurate GPS system. With a network of satellites spanning 50,000 kilometers and traveling through space at 300 kilometers a second, a cosmic kink could disturb the GPS clocks. This quantum crack would require 170 seconds to jump across the networks.

GPS clocks could be interrupted by other factors, but Deverianko and Pospelov believe that only dark matter could disturb the system’s timekeeping in a certain way.

Derevianko is currently pulling data from 15 years of GPS records to search for signs of dark matter’s presence. If no fingerprints are detected, he will use the ground-based atomic clocks belonging to the Network for European Accurate Time and Frequency Transfer.
If dark matter is nothing more than cosmic kinks, it could give some people a new thing to grumble about. “I hear these stories about people getting lost using GPS,” said Derevianko. “Now they could have another excuse: maybe it was dark matter that caused them to lose their way.”

Magnetic Fields of an Ancient Meteorite Give Clues to the Formation of Our Universe


Ancient meteorite's magnetic fields gives clues to the formation of the universe

Excerpt from
savingadvice.com 

A better understanding of how the universe was formed comes from what is left of a meteorite. The meteorite is named Semarkona, and it touched down in India in the 1940′s. Arizona State University’s School of Earth and Space Exploration wanted to measure the magnetic levels of the meteorite, and in doing so, they have shown we are closer to understanding how the solar system was formed.

It would seem rather insignificant given its size of just one and a half pounds, but it was formed over four and a half billion years ago. Researchers admit the magnetic flux of the rock mimics the magnetic forces here on the planet.

Every magnetic fluctuation of Semarkona has been mapped and the fluctuations of the magnetic field recorded in a study that is the first of its kind. This has given researchers more insight into the magnetic fields that were pivotal in forming the universe.

The study, aptly named Solar nebula magnetic fields recorded in the Semarkona meteorite was published in the November 13 issue of the journal Science.

The World is Not Enough: A New Theory of Parallel Universes is Proposed



Excerpt from universetoday.com

by Tim Reyes



Do we exist in a space and time shared by many worlds? And are all these infinite worlds interacting? A new theory of everything is making the case.

Imagine if you were told that the world is simple and exactly as it seems, but that there is an infinite number of worlds just like ours.

They share the same space and time, and interact with each other.
These worlds behave as Newton first envisioned, except that the slightest interactions of the infinite number create nuances and deviations from the Newtonian mechanics. What could be deterministic is swayed by many worlds to become the unpredictable.

This is the new theory about parallel universes explained by Australian and American theorists in a paper published in the journal Physics Review X. Called  the “Many Interacting Worlds” theory (MIW), the paper explains that rather than standing apart, an infinite number of universes share the same space and time as ours.

They show that their theory can explain quantum mechanical effects while leaving open the choice of theory to explain the universe at large scales. This is a fascinating new variant of Multiverse Theory that, in a sense, creates not just a doppelganger of everyone but an infinite number of them all overlaying each other in the same space and time.

Rather than island universes as proposed by other multiverse theories, Many Interacting Worlds (MIW) proposes many all lying within one space and time.

Cosmology is a study in which practitioners must transcend their five senses. Einstein referred to thought experiments, and Dr. Stephen Hawking — surviving and persevering despite having ALS — has spent decades wondering about the Universe and developing new theories, all within his mind.

The “Many Interacting Worlds” theory, presented by Michael Hall and Howard Wiseman from Griffith University in Australia, and Dirk-André Deckert from the University of California, Davis, differs from previous multiverse theories in that the worlds — as they refer to universes — coincide with each other, and are not just parallel. 

The theorists explain that while the interactions are subtle, the interaction of an infinite number of worlds can explain quantum phenomena such as barrier tunneling in solid state electronics, can be used to calculate quantum ground states, and, as they state, “at least qualitatively” reproduce the results of the double-slit experiment.

Schrödinger, in explaining his wave function and the interaction of two particles (EPR paradox) coined the term “entanglement”. In effect, the MIW theory is an entanglement of an infinite number of worlds but not in terms of a wave function. The theorists state that they were compelled to develop MIW theory to eliminate the need for a wave function to explain the Universe. It is quite likely that Einstein would have seen MIW as very appealing considering his unwillingness to accept the principles laid down by the Copenhagen interpretation of Quantum Theory.

While MIW theory can reproduce some of the most distinctive quantum phenomena, the theorists emphasize that MIW is in an early phase of development. They state that the theory is not yet as mature as long-standing unification theories. In their paper, they use Newtonian physics to keep their proofs simple. Presenting this new “many worlds” theory indicates they had achieved a level of confidence in its integrity such that other theorists can use it as a starter kit – peer review but also expand upon it to explain more worldly phenomena.



Two of the perpetrators of the century long problem of unifying General Relativity Theory and Quantum Physics, A. Einstein, E. Schroedinger.
Two of the perpetrators of the century-long problem of unifying General Relativity Theory and Quantum Physics – Albert Einstein, Erwin Schroedinger.

The theorists continue by expounding that MIW could lead to new predictions. If correct, then new predictions would challenge experimentalists and observers to recreate or search for the effects.
Such was the case for Einstein’s Theory of General Relativity. For example, the bending of the path of light by gravity and astronomer Eddington’s observing starlight bending around Sun during a total Solar Eclipse. Such new predictions and confirmation would begin to stand MIW theory apart from the many other theories of everything.

Multiverse theories have gained notoriety in recent years through the books and media presentations of Dr. Michio Kaku of the City College of New York and Dr. Brian Greene of Columbia University, New York City. Dr. Green presented a series of episodes delving into the nature of the Universe on PBS called “The Fabric of the Universe” and “The Elegant Universe”. The presentations were based on his books such as “The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos.”

Hugh Everett’s reinterpretation of Dr. Richard Feynman’s cosmological theory, that the world is a weighted sum of alternative histories, states that when particles interact, reality bifurcates into a set of parallel streams, each being a different possible outcome. In contrast to Feynmann’s theory and Everett’s interpretation, the parallel worlds of MIW do not bifurcate but simply exist in the same space and time.  MIW’s parallel worlds are not a consequence of “quantum behavior” but are rather the drivers of it.

Hall states in the paper that simple Newtonian Physics can explain how all these worlds evolve. This, they explain, can be used effectively as a first approximation in testing and expanding on their theory, MIW. Certainly, Einstein’s Special and General Theories of Relativity completes the Newtonian equations and are not dismissed by MIW. However, the paper begins with the simpler model using Newtonian physics and even explains that some fundamental behavior of quantum mechanics unfolds from a universe comprised of just two interacting worlds.

So what is next for the Many Interacting Worlds theory? Time will tell. Theorists and experimentalists shall begin to evaluate its assertions and its solutions to explain known behavior in our Universe. With new predictions, the new challenger to Unified Field Theory (the theory of everything) will be harder to ignore or file away with the wide array of theories of the last 100 years. Einstein’s theories began to reveal that our world exudes behavior that defies our sensibility but he could not accept the assertions of Quantum Theory. Einstein’s retort to Bohr was “God does not throw dice.” The MIW theory of Hall, Deckert, and Wiseman might be what Einstein was seeking until the end of his life. In titling this review of their theory as “The World is not Enough,” I would also add that their many interacting worlds is like a martini shaken but not stirred.
