Because this information is then lost forever, that's incompatible with quantum mechanics.
Quantum mechanics doesn't allow you to destroy information.
So um and there are other puzzles about black holes.
You see, if we watch somebody falling into a black hole, we as outside observers would never actually see them.
falling through the horizon.
What we'd see is that they their time would effectively slow down and they would them anything they were doing, anything they were using like clocks, would just slow down and freeze.
And the ultimate picture we would have of them is that they're just frozen on the horizon.
And so again, people have wondered, you know, if what happens inside the black hole is never actually observable, um is it really true that the interior of a black hole even exists?
So we applied this method of analytic continuation to the metric of a black hole.
We actually did it for ourselves, or my student did it for himself, but uh later we discovered that Einstein himself had used the same uh method.
Uh before the conventional
Description of a black hole was discovered by Martin Kruskel.
uh Martin Kreskell discovered how to
uh describe the transition across the horizon um in a
let's say kosher mathematical way, um uh I think around nineteen sixty.
But even before that, Einstein was puzzled by the black hole horizon.
And Einstein and Rosen, the same people, uh Einstein Podolsky Rosen, the famous EPR paradox in quantum mechanics, the same Rosen with Einstein, solved the equations for a black hole in a different way
And basically they used this technique to transition through the horizon, and they discovered what is called the Einstein-Rosen Bridge.
And this connects two exteriors uh of the black hole, which are really distinct universes.
And as you go through the as you follow the solution uh to the horizon and beyond, you emerge in this the other side of the black hole.
