Physicists Find a Way to See the ‘Grin’ of Quantum Gravity
...nature of gravity and space-time must be revealed — always hide behind the horizons of black holes. “Even a few years ago it was a generic consensus that, most likely,...
The Year in Physics
...April — a dark void, encircled by a luminous ring, humanity’s first-ever look at a black hole. The existence of black holes had not been in doubt, of course: Astronomers...
A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws
...of colliding black holes is resolved by a “hidden” symmetry that links low- and high-frequency deformations of the shape of the black holes. Like other researchers, Dubovsky doesn’t seem to...
A Cosmic-Ray Hunter Takes to the Sky
...that the bigger the better, so the supermassive black holes are usually a little bit ahead. It could be somewhere in the middle: intermediate-mass black holes. Or ultrahigh-energy cosmic rays...
Why Did The Universe Begin?
...made that black holes radiate, that quantum processes are responsible for this, and that this radiation could be captured by purely spatial geometries. And that was the inspiration to try...
Standard Model of Cosmology Survives a Telescope’s Surprising Finds
...universe; maybe the gas is denser; maybe somehow it is flowing in faster. I think we’re still learning about those processes.” Somerville also studies the possibility that black holes interfered...
Gravitational Waves Should Permanently Distort Space-Time
...loss of information in black holes, a very deep issue in the structure of space and time.” A Scar in Space-Time Why would a gravitational wave permanently change space-time’s structure?...
A Century Later, New Math Smooths Out General Relativity
...black holes. This could occur even in a space with small amounts of matter, if it’s concentrated strongly enough. In a recent paper, Conghan Dong, a graduate student at Stony...
Bubble Experiment Finds Universal Laws
...basis,” said Amir Pahlavan, a mechanical engineer at Princeton University and a co-author of the recent work. “For black holes, it’s much harder to study and observe them.” The End...
