A Black Hole’s Orbiting Ring of Light Could Encrypt Its Inner Secrets
...to unlock the secrets of Kerr black holes,” he said, referring to the kind of spinning black holes created when stars die and gravitationally collapse. (The photon ring forms concurrently.)...
What Drives Galaxies? The Milky Way’s Black Hole May Be the Key.
...supermassive black holes in the center. We let these black holes swallow gas and release energy until the whole thing flew apart, like a pressure cooker pot. Suddenly, the elliptical...
At Long Last, Mathematical Proof That Black Holes Are Stable
...Kerr, are stationary, Giorgi said. “These formulas apply to black holes that are just sitting there and never change; those aren’t the black holes we see in nature.” To assess...
Mass and Angular Momentum, Left Ambiguous by Einstein, Get Defined
...two black holes that are in the process of merging, and they want to determine the mass of each individual black hole prior to the merger, as opposed to that...
Will the James Webb Space Telescope Reveal Another Earth?
...the blanks in these models. Strogatz (16:51): What about black holes? Or the so-called supermassive black holes? Are we going to be getting some information about their role in this...
Black Hole Image Reveals the Beast Inside the Milky Way’s Heart
...a key aspect of black holes. No matter their size, or the environment they live in, once you arrive at the edge of a black hole, gravity takes over.” In...
Where Do Space, Time and Gravity Come From?
...black hole, all of the information, all the quantum mechanical information inside a black hole, can in certain circumstances be thought of as spread out on the boundary of the...
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
...Yunger Halpern and other theorists showed that Kirkwood-Dirac negativity also underlies quantum behavior in contexts besides metrology, including quantum thermodynamics and fast information scrambling in black holes. The researchers say...
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...
