Mind-Bending Study Suggests Time Did Actually Exist Before The Big Bang

Posted by in categories: cosmology, information science, physics

According to a straightforward interpretation of general relativity, the Big Bang wasn’t the start of ‘everything’.

Taking Einstein’s famous equations at face value and making as few assumptions as possible, a team of researchers has rewound the clock on our Universe to find it wouldn’t lead to a stopping point at all, but would take us through a different kind of beginning into a flipped space.

To understand what all the fuss over the Big Bang is, we need to rewind a bit to understand why physicists think it may not have been the start of everything.

Stephen Hawking’s Final Theory About Our Universe Will Melt Your Brain

Posted by in categories: cosmology, neuroscience, physics

Nope. Too late already. It’s been molten long ago already ha…


Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.

The paper, published in the Journal of High Energy Physics in May, puts forward that the Universe is far less complex than current multiverse theories suggest.

Why Don’t Black Holes Swallow All of Space? This Explanation Is Blowing Our Minds

Posted by in categories: cosmology, physics

Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).

But given their talent for consumption, why don’t black holes just keep expanding and expanding and simply swallow the Universe? Now, one of the world’s top physicists has come up with a new explanation.

Conveniently, the idea could also unite the two biggest theories in all of physics.

The Physics of Death (and What Happens to Your Energy When You Die)

Posted by in categories: life extension, neuroscience, physics, space

When we die, our energy is redistributed throughout the universe according to the law of conservation of energy. While this should not be confused with our consciousness living forever, our energy continuing after we’re gone could make death a less scary prospect.

Doctoral Student Just Published a Paper Describing How Time Travel Would Be Possible

Posted by in categories: cosmology, physics, time travel

And how to build a time machine.


The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing it right now, aren’t we? We are all traveling into the future one second at a time.

But that was not what you were thinking. Can we travel much further into the future? Absolutely.

Silica paradox: Scientists discover seemingly ‘impossible’ material

Posted by in categories: chemistry, physics, supercomputing

An international team of physicists and materials scientists from NUST MISIS, Bayerisches Geoinstitut (Germany), Linkoping University (Sweden), and the California Institute of Technology (U.S.) has discovered an “impossible” modification of silica-coesite-IV and coasite-V materials, which seems to defy the generally accepted rules for the formation of chemical bonds in inorganic materials formulated by Linus Pauling, who won the 1954 Nobel Prize in Chemistry for that discovery. The research results were published in Nature Communications on November 15th, 2018.

According to Pauling’s rules, the fragments of the atomic lattice in inorganic materials are connected by vertices, because bonding by faces is the most energy-intensive way to form a chemical connection. Therefore, it does not exist in nature. However, scientists have proved, both experimentally and theoretically, using NUST MISIS’ supercomputer, that it is possible to form such a connections if the materials are at ultra-high pressure conditions. The obtained results show that fundamentally new classes of materials exist at extreme conditions.

“In our work, we have synthesized and described metastable phases of high-pressure silica: coesite-IV and coesite-V. Their crystal structures are drastically different from any of the earlier described models,” says Igor Abrikosov, leader of the theoretical research team. “Two newly discovered coesites contain octahedrons SiO6, that, contrary to Pauling’s rule, are connected through common face, which is the most energy-intensive chemical connection. Our results show that the possible silicate magmas in the lower mantle of the Earth can have , which makes these magmas more compressible than predicted before.”

Physics Suggests That Our Dreams Might Be Glimpses Of Other Dimensions

Posted by in categories: cosmology, physics

If you have ever looked into the ‘many world’s theory’ you know that the world we live in is quite possibly one of many. Regardless of the multiverse hypotheses, you choose to follow/look into each one is truly fascinating for a number of reasons.

Basically, most of them touch on how there are many different worlds, universes, dimensions, or whatever you would like to call them. Each one the same as our own but also different in some way. For instance, in another world, you might be living the same life as you are now but perhaps politics had gone in a different direction. Maybe all of the presidents that were elected here in the US were opposite from how they are in our world. Maybe everything is the same except for you have different colored hair? The differences between worlds could be minuscule or extreme, it all varies.

The Key to Understanding AI May be Buried in the Laws of Physics

Posted by in categories: mathematics, physics, robotics/AI, space

Deep learning has been making it possible for powerful machines to approximate and imitate abilities and techniques once thought to be uniquely human. Mathematicians have struggled to explain how they work so well and may now get some answers by looking outside mathematics and into the nature of the universe.
