Sabine Hossenfelder: Black holes vs. quantum mechanics = something has to give
Her view: Most physicists believe that the solution is that the Hawking radiation somehow must contain information after all.
The day Stephen Hawking undercut the multiverse
Regis Nicoll: Stephen Hawking had for many years considered the idea that “black holes are birthing centers for Star Trek phenomena like wormholes, time tunnels and multiple universes.” Then, in 2004, he turned on the idea.
Theorizing information out of a black hole
Not really being able to integrate information with matter and energy surely means it is hard to say whether information could really be destroyed.
Are black holes partly a philosophy question?
The black hole has always occupied a sort of space in the middle, between science and philosophy. It’s good to see that acknowledged. From ScienceDaily: Erik Curiel studied Philosophy as well as Theoretical Physics at Harvard University and the University of Chicago, and the primary aim of his current DFG-funded research project is to develop […]
Proposed black hole information paradox solution: They become white holes
According to a new paper, white holes, the theoretical opposite of black holes, may account for dark matter, and may even predate the universe. They may even, according to Carlo Rovelli, explain the direction of time: A black hole is one prediction of Einstein’s theory of general relativity. Another is known as a white hole, […]
What would a black hole really look like?
If you saw it up close? If you were to take a photo of a black hole, what you would see would be akin to a dark shadow in the middle of a glowing fog of light. Hence, we called this feature the shadow of a black hole . Interestingly, the shadow appears larger than you […]
Stephen Hawking’s final paper, just released, tackled the “information paradox”
Quantum theory specifies that information is never lost but what happens to the information when a black hole vanishes? In the latest paper, Hawking (1942-2018) and his colleagues show how some information at least may be preserved. Toss an object into a black hole and the black hole’s temperature ought to change. So too will a […]
Black holes do not behave as string theorists say they should
Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, explains, Three weeks ago, Steinhauer’s group reported results from a new experiment in which they have now measured the temperature of the fluid black hole: Observation of thermal Hawking radiation at the Hawking temperature in an analogue black hole Juan Ramón Muñoz de Nova, Katrine […]
