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...
Beyond the Second Law
...mathematical. Some describe high-energy particles, like those smashed together at CERN; one describes chaos in black holes; and one describes the universe’s expansion. Experimentalists have tested some quantum fluctuation relations...
Massive Black Holes Shown to Act Like Quantum Particles
Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave. When...
A New Tool for Finding Dark Matter Digs Up Nothing
...gravitational waves that pass through the planet, created by the distant collisions of black holes, only stretch and compress each mile of Earth’s surface by one-thousandth the diameter of an...
Tiny Galaxies Reveal Secrets of Supermassive Black Holes
...the first black holes. Many of those galaxies collided over time, and their black holes merged. Through some mixture of mergers and gobbling up of matter, the first “seed” black...
A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws
...of colliding black holes is resolved by a “hidden” symmetry that links low- and high-frequency deformations of the shape of the black holes. Like other researchers, Dubovsky doesn’t seem to...
