19 Women Leading Math and Physics
...isn’t researching black holes. Miranda Cheng, another high-school dropout turned physicist-mathematician, is now chasing a mysterious connection between string theory, algebra and number theory. The Princeton University mathematician Maria Chudnovsky’s...
Topology 101: The Hole Truth
...cheese. A topologist would say that all but the first example are holes. But to understand why – and why mathematicians even care about holes in the first place —...
Squishy or Solid? A Neutron Star’s Insides Open to Debate
...come from black holes, which are more tractable beasts from a computational standpoint. But this signal involved lighter objects and went on for much longer than the black hole mergers....
Why This Universe? A New Calculation Suggests Our Cosmos Is Typical.
...an intricate calculation of how quantum particles behave in the curved space-time of a black hole. To his surprise, in 1974 he found that black holes do indeed radiate. Another...
The Quantum Secret to Superconductivity
...matte-black ceramic in a class of materials called cuprates that are the most potent superconductors known. The findings, reported today in the journal Nature, provide a major clue about the...
Why Gravity Is Not Like the Other Forces
...and black holes: Black holes are the reason it’s difficult to combine gravity with quantum mechanics. Black holes can only be a consequence of gravity because gravity is the only...
Pondering the Bits That Build Space-Time and Brains
...life. We argued that the collection of ways in which black holes can arrange the information they contain is like this library. Like the books, the black hole’s “microstates” consist...
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 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...
