“We must be able to influence the interior of one of these black holes by ‘tagging’ its radiation, and thus sending a message to the black hole’s interior,” he said. in a 2017 interview with Quanta. He added, “It sounds crazy.”
Ahmed Almheiri, a physicist at NYU Abu Dhabi, recently noted that by manipulating radiation escaping a black hole, he could create a cat inside that black hole. “I could do something with the particles coming out of the black hole, and suddenly a cat would appear in the black hole,” he said.
He added, “We all have to get used to this.”
Metaphysical turmoil occurred in 2019. That year, two groups of theorists did detailed calculations showing that information leaking through wormholes would fit the model predicted by Dr. Page. A paper by Geoff Penington, now of the University of California, Berkeley. And the other is by MIT’s Netta Engelhardt; Don Marolf of the University of California, Santa Barbara; Henry Maxfield, now at Stanford University; and Dr. Almheiri. The two groups published their papers on the same day.
“And the ultimate moral of the story is, if your theory of gravity includes wormholes, then you have information emerge,” Dr. Penington said. “If it doesn’t include the wormhole, then you probably won’t get the information.”
He added, “Hawking is not including wormholes, and we are including wormholes.”
Not everyone believes in this theory. And testing it out is challenging, as particle accelerators will probably never be powerful enough to create black holes in the lab for study, although some groups of experimenters hope to be able to simulate Black holes and wormholes in quantum computers.
And even if this physics turns out to be correct, Dr. Mermin’s magic still has an important limitation: Neither wormholes nor entanglement can transmit a message, even human, faster than speed light level. So much for time travel. The oddity only became apparent after the fact, when the two scientists compared their observations and discovered that they matched – a process related to classical physics, subject to the rate limit. coined by Einstein.
