In Expanding de Sitter Space, Quantum Mechanics Gets Even More Elusive
...in de Sitter: to lose your prejudice.” Pushing Boundaries To try to make sense of the quantum mechanics of de Sitter space, some physicists have turned to black holes. Black...
Singularities in Space-Time Prove Hard to Kill
...cosmos and the hearts of black holes would truly mark edges of the map where clocks can’t tick and space stops. “Inside of black holes, I am positive there is...
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....
The Quantum Secret to Superconductivity

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...
Gravity Seems Holographic. What Does That Mean for Reality?
