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?
...with Janna Levin, we’d eventually be talking about black holes. LEVIN: [laughing] I can turn any conversation into a conversation about black holes. PRESKILL: No surprise there. Actually, I think...
The Universe Is Not a Simulation, but We Can Now Simulate It
...York, coded some of the first black holes, putting them into GASOLINE in 2008. Skipping or simplifying tons of physics, she programmed an equation dictating how much gas the black...
How Space and Time Could Be a Quantum Error-Correcting Code
...both kinds of universes contain black holes. “The most fundamental property of gravity is that there are black holes,” said Harlow, who is now an assistant professor of physics at...
Michael Atiyah’s Imaginative State of Mind
...comes from the entire mass of the universe. It doesn’t cancel itself out, it doesn’t have positive or negative value, it all adds up. So however far away the black...
Discoveries Fuel Fight Over Universe’s First Light
...evidence that supermassive black holes existed hundreds of millions of years before anyone thought possible. The new discoveries should make clear just how much black holes contributed to the reionization...
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...
The Particle That Broke a Cosmic Speed Limit
...sensors in every direction, instead of painting a telltale pattern that could be matched to, say, the locations of supermassive black holes or colliding galaxies, they created confusion. “It’s hard...
