Paradoxical Crystal Baffles Physicists
...Lifshitz-Kosevich formula was presaged in 2010 by Sean Hartnoll and Diego Hofman, both then at Harvard University, in a paper that recast strongly correlated materials as higher-dimensional black holes, those...
An Astrophysicist Who Maps the Universe’s Terra Incognita
...reactor — these black holes. So black holes are compact inner parts of the stars that have gravitationally collapsed and have become unbelievably dense. There’s no analogue. It’s not lead;...
Interactive: What Is Space?
...of space-time, overturning Isaac Newton’s classic theory and correctly predicting the existence of black holes and gravity’s ability to bend light. But a century later, the fundamental nature of space-time...
A Glimpse Through a Cosmic Keyhole
...galaxies, meaning that they have jets of material streaming out in two directions, probably powered by the supermassive black holes spinning at the galaxies’ centers. (The jets emit radio light...
An Enormous Gravity ‘Hum’ Moves Through the Universe
...black holes get relatively close to each other? There were reasons to think that instead of merging, as smaller black holes do, supermassive black holes just rotate around each other...
Early Life in Death Valley
Paul Knauth scrambled up a steep, rocky canyon in the Black Mountains of Death Valley National Park, sporting gloves and a walking stick to help navigate the sharp scree. The...
Theories of Everything, Mapped
...a single framework. In their day-to-day work, though, many physicists focus more on rooting out dark matter, solving the Standard Model’s hierarchy problem, and pondering the goings-on in black holes,...
Where Gravity Is Weak and Naked Singularities Are Verboten
...a universe like ours. Always, singularities lay at the centers of black holes — sinkholes in space-time that are so steep that no light can climb out. He told his...
What Is Quantum Teleportation?
...black holes, which have a shared interior — a kind of wormhole connecting the inside of these two black holes. And the paper by Einstein, [Boris] Podolsky and Rosen was...
