By tearing apart the fabric of space beyond the point of no return, the group was able to preserve the information rule of quantum mechanics. "We took Hawking's original argument," he says, "and very carefully ran it backwards."Īnd Polchinski and his colleagues found one way to keep things from vanishing when they fall inside a black hole - they got rid of the inside. People thought that if you fell into a black hole, your spaghettified remains would always be in there, trapped beyond the point of no return.ġ3.7: Cosmos And Culture Voyage To The Center Of A Black Hole "If it were violated, everything falls apart."įor a long time, black holes stretched this rule, but they didn't break it. "Everything is built on it," says Susskind. But it should always be possible, at least in theory, to look at all those rearranged atoms and work out that they were once part of a human of your dimensions and personality. They can be rearranged (radically if you happen to slip inside a black hole). Put another way, the atoms in your body are configured in a particular way. This "no inside" idea may sound outrageous, but it's actually a stab at solving an even bigger problem with black holes.Īccording to the dominant theory of physics - quantum mechanics - information can never disappear from the universe. "Probably that's the end of space itself there's no inside at all." So what's inside the black hole? Nothing, Polchinski says.
But Polchinski has a new version of things: "Our hypothesis is that the inside of a black hole - it may not be there," he says. In Einstein's version of events, that's the end. "It'd be like something on Game of Thrones." "It'd be kind of medieval," says Polchinkski. He says the technical term for this stretching is spaghettification. "The gravity wants to sort of stretch you in one direction and squeeze you in another," says Joe Polchinski, a physicist at the University of California, Santa Barbara. And gravity from the black hole is starting to pull on your feet more than your head.
But passing the point of no return - you wouldn't even notice it." "It's kind of like you're rowing on Niagara Falls, and you pass the point you can't row fast enough to escape the current," Susskind says. And eventually you pass a point of no return. At first, you're not going to notice much of anything - but the black hole's gravity is getting stronger and stronger. There's a long-standing view about what would happen if you fell into one of these holes. Our hypothesis is that the inside of a black hole - it may not be there.
