Mar. 25, 2014 — Physicists are using surprising ideas and mathematical tools originating in string theory to guide research into strange materials that are cropping up in condensed matter laboratories. There are a ... full story -
Exploding Stars Prove Newton's Law of Gravity Unchanged Over Cosmic Time
Mar. 24, 2014 — Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. Newton's ... full story -
Einstein's 'Spooky' Theory May Lead to Ultra-Secure Internet
Mar. 24, 2014 — Einstein's skepticism about quantum mechanics may lead to an ultra-secure Internet, a new paper suggests. In 1935, Einstein and researchers highlighted a 'spooky' theory in quantum ... full story -
Plugging the Hole in Hawking's Black Hole Theory
Mar. 24, 2014 — Recently physicists have been poking holes again in Stephen Hawking's black hole theory -- including Hawking himself. Now another professor has jumped into the fray. He believes he has solved ... full story -
Tremors of the Big Bang: First Direct Evidence of Cosmic Inflation
Mar. 17, 2014 — Almost 14 billion years ago, the universe we inhabit burst into existence in an extraordinary event that initiated the Big Bang. In the first fleeting fraction of a second, the universe expanded ... full storyMore: -
Researchers Propose a New Way to Detect the Elusive Graviton

Feb. 19, 2014 — Researchers have provided the first English translation and an analysis of one of Albert Einstein's little-known papers, "On the cosmological problem of the general theory of ... full story -
Einstein's Conversion from a Belief in a Static to an Expanding Universe
Feb. 17, 2014 — Albert Einstein accepted the modern cosmological view that the universe is expanding long after many of his contemporaries. Until 1931, physicist Albert Einstein believed that the universe was ... full story -
How Hypergravity Impacts Electric Arcs
Dec. 18, 2013 — A new study on electric discharge behavior under intense gravitational forces shows that its dynamic changes as gravity increases. Arc discharges are common in everyday conditions like welding or in ... full story -
Recipe for a Universe: Apply Heat and Stir
Dec. 10, 2013 — Apply heat and stir; an expanding universe can emerge in a remarkably simple way, say scientists. When soup is heated, it starts to boil. When time and space are heated, an expanding universe can ... full story -
You Can't Get Entangled Without a Wormhole: Physicist Finds Entanglement Instantly Gives Rise to a Wormhole
Dec. 5, 2013 — Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics -- so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a ... full story -
'Spooky Action' Builds a Wormhole Between 'Entangled' Quantum Particles
Dec. 3, 2013 — New research indicates a phenomenon known as "quantum entanglement" might be intrinsically linked with wormholes, hypothetical features of space-time that could link one part of the ... full story -
Squeeze and You Shall Measure: Squeezed Coherent States Shown to Be Optimal for Gravitational Wave
Nov. 13, 2013 — Extremely precise measurements of distances are key in all techniques used to detect gravitational waves. To increase this precision, physicists have started using quantum effects linked with ... full story -
Experimental Quest to Test Einstein's Speed Limit
July 29, 2013 — Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual ... full story -
Largest Magnetic Fields in the Universe
July 26, 2013 — Numerical simulations show for the first time the occurrence of an instability in the interior of neutron stars that can lead to gigantic magnetic fields, possibly triggering one of the most dramatic ... full story -
Behavior of Turbulent Flow of Superfluids Is Opposite That of Ordinary Fluids
July 25, 2013 — A superfluid moves like a completely frictionless liquid, seemingly able to propel itself without any hindrance from gravity or surface tension. The physics underlying these materials -- which appear ... full story -
Space-Time Is Not the Same for Everyone
July 9, 2013 — Before the Big Bang, space-time as we know it did not exist. So how was it born? The process of creating normal space-time from an earlier state dominated by quantum gravity has been studied for ... full story
