Does Time Really Flow? New Clues Come From a Century-Old Approach to Math.
...these entire ideas.” This new way of thinking about information may suggest a resolution to the black hole information paradox, which asks what happens to information swallowed by black holes....
The Quantum Thermodynamics Revolution
...to everything else: the sun, black holes, living beings and the entire universe. The theory is so simple and general that Albert Einstein deemed it likely to “never be overthrown.”...
Wormhole Experiment Called Into Question
...and vice versa, effectively putting on and taking off the glasses. They watch how particles, black holes and wormholes transform as one switches between the two perspectives. Calculations that are...
Do We Need a New Theory of Gravity?
...when we have to open eyes for something new. But we know something is not quite right in Einstein’s theory of general relativity. When it comes to black holes, for...
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...
How Gravity Is a Double Copy of Other Forces
...trick in gravity’s repertoire. Black holes famously warp space-time intensely enough to trap light, and spinning black holes drag the warped space-time fabric around with them. The equations are super...
New Math Proves That a Special Kind of Space-Time Is Unstable
...black hole will form. Here’s the proof of instability: Moschidis showed that when he adds even a minuscule amount of matter to an AdS space-time, a black hole (or black...
Physicists Create a Holographic Wormhole Using a Quantum Computer
...two black holes is created by EPR-like correlations between the microstates of the two black holes,” and that the duality might be more general than that: “It is very tempting...
Physicists Uncover Geometric ‘Theory Space’
...of space-time in our own universe, and yet gravity there works in much the same way as it does here. Both geometries, for instance, give rise to black holes —...
