How Quantum Pairs Stitch Space-Time
...named Jacob Bekenstein showed that the information about a black hole’s interior is encoded in its two-dimensional surface area (the “boundary”) rather than within its three-dimensional volume (the “bulk”). Twenty...
Wormholes Untangle a Black Hole Paradox
...EPR paradox, named for its authors, Einstein, Boris Podolsky and Nathan Rosen). The other showed how two black holes could be connected through far reaches of space through “wormholes” (ER,...
Mathematicians Chase Moonshine’s Shadow
...should offer a way to construct a model of three-dimensional quantum gravity, in which 194 natural categories of elements in the monster group correspond to 194 classes of black holes....
In LHC’s Shadow, America’s Collider Awakens
...the plasma’s peculiar mathematical relationship to black holes, have revealed that it is an almost “perfect” liquid, possessing the lowest viscosity (or internal friction) allowed by quantum physics. A monitor...
Joint Dust Analysis Deflates Big Bang Signal
...shrinks to a point. The theoretical arguments for why it should bounce strike most experts as highly speculative. And the non-bounciness of black holes suggests it would not do so....
In a Multiverse, What Are the Odds?
...encountered the measure problem in the 1990s as a graduate student working with Stephen Hawking, the doyen of black hole physics. Black holes prove there is no such thing as...
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...
Betting on the Future of Quantum Gravity
...constitute black holes. Profound conceptual puzzles posed by black holes suggest that the true theory will demand a radical new perspective on the universe — one in which space and...
Physicists Eye Quantum-Gravity Interface
...gravitational fields. Quantum mechanics and general relativity dominate in disparate domains, and they seem to converge only in enormously dense, quantum-size black holes. In the laboratory, as the physicist Freeman...
