Stephen Hawking may have just solved one of the most vexing mysteries in physics — the "information paradox."
Einstein's theory of general relativity predicts that the physical information about material gobbled up by a black hole is destroyed, but the laws of quantum mechanics stipulate that information is eternal. Therein lies the paradox.
Hawking — working with Malcolm Perry, of the University of Cambridge in England, and Harvard University's Andrew Stromberg — has come up with a possible solution: The quantum-mechanical information about infalling particles doesn't actually make it inside the black hole.

The technical article has not been published yet .... Waiting for it!!!!!
ReplyDeleteOh, Corina, you are so great. Thanks for sharing this.
ReplyDeleteFascinating animation. Where does it come from?
ReplyDeleteAlso -- postulating omniscience impossible implies the necessity of horizons, if possibly shifting. Then the horizons themselves can substitute for the omniscient they displace. This isn't the topic of the firewall paradox and debate, but the center stage played in it by BH horizons, smacks of the kind of attention you'd expect horizons to get from such a theological mutation.
This simulation shows how one black hole is passing in front of the other and the credit goes to Cornell University.
ReplyDeleteObviously doesn't show what Mr. Hawking is talking about...but is always better to show 2 black holes than one. And I'm sure you know why Boris Borcic ;)
The tech paper hasn't been published yet but the debate has serious grounds in my opinion. ;)
ReplyDeleteYes, the debate is also interesting :D
ReplyDeleteMaybe dark matter comes into the equation somehow
ReplyDeleteI remember reading about information being stored on the horizon of a black hole in Leonard Susskind's 2008 book The Black Hole War. Is this announcement some new proof of it or something? I'm not understanding what Hawking has actually announced.

Typical Lubos Motl : If Ms Hossenfelder has tried something and failed, it doesn't mean that it's wrong. Ms Hossenfelder is likely to fail whenever she tries to do something that makes sense.

ReplyDeleteCorina Marinescu Sss - j'ose même pas rougir:) The gif shows two BH fusing, what's the prototypical source of gravitational waves; in turn revealed here by the peculiar rippling of the background sky. The things must move near light speed so the period tells the size.
ReplyDeleteNothing disappear everything it is contained on a continuous.
ReplyDeleteAlbert Einstein. True. Mater will destroy into substantial. It's look like gateway to another dimension.
