Nearly a century after it was theorized, Harvard scientists have succeeded in creating metallic hydrogen. In addition to helping scientists answer fundamenta...
Vera Rubin, Astrophysicist Who Confirmed Existence Of Dark Matter, Dies At 88
The astrophysicist's groundbreaking research on spiral galaxies provided evidence of invisible dark matter. She was a pioneer in an era when women were excluded from many astronomy programs.
Albert Einstein Facts: 51 Things You Didn't Know About Einstein
Amazing Albert Einstein facts and things you didn't know. Here are some amazing and little-known facts about life of one of the greatest minds of our time.
Quantum Physicists Probe Fabric of Spacetime to Solve Mystery of Dark Energy
One of the great mysteries of the cosmos is why it is expanding at an apparently accelerating rate. Physicists have suggested an outward force, dubbed "dark energy," causes this expansion, but they ha...
We May Have Found a Way to Cheat the Second Law of Thermodynamics
Physicists created a new quantum theorem for entropy, and included is a possible exception.
The case for black holes being nothing but holograms just got even stronger
If anything can sum up just how little we truly know about the Universe, it’s black holes. We can’t see them because not even light can escape their gravitational pull, we have no idea what they’re ma...
2016 Nobel Prize In Physics Awarded To David Thouless, Duncan Haldane And Michael Kosterlitz
They were honored for their work in revealing the secrets of exotic matter. Their discoveries, using advanced mathematics, had boosted research in condensed matter physics and raised hopes for uses in...
A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
The Pressure Is On To Make Metallic Hydrogen
Scientists are getting close to turning hydrogen into a metal — both in liquid form and maybe even solid form. The rewards, if they pull it off, are worth the effort.
China Launches The First Quantum Communications Satellite – And What Is That, Exactly?
Congratulations are in order for China: by launching the world's first quantum communications satellite, the country has achieved an interesting — if..
Dark matter may just be a bunch of ancient black holes
An invisible "dark matter" outweighs all the stars in space by 4:1. But gravitational waves may soon unmask the shadowy culprit.
Researchers are a step closer to making a real-life invisibility cloak
Researchers from the UK have successfully made a raised object appear flat to electromagnetic waves – meaning that they are a step closer to having a full-blown cloaking device that can hide objects. ...
The biggest explosions in the Universe
These bursts are a million times brighter than entire galaxies
The Higgs-shaped elephant in the room
Higgs bosons should mass-produce bottom quarks. So why is it so hard to see it happening?
It took centuries, but we now know the size of the Universe
The sheer scale of the cosmos is hard to imagine, and even harder to put an accurate figure on. But thanks to some ingenious physics we now have a good idea of just how big it is
Is Particle Physics About to Crack Wide Open?
Hints of an unexpected new particle could be confirmed within days—and if it is, the Standard Model could be going down
