Graduate What Happens to Information When a Star Becomes a Black Hole?

[FallenApple]

So we know from the Holographic Principle that the information on the cosmological horizon represents what is inside.

Suppose a large star is about to turn into a black hole. Well, that star is represented by information on some far away horizon. When that star turns into a black hole, it has an event horizon itself on which the information on it describes what happens inside of it. So what happens to the information of the star that was originally on the outer horizon? Is it lost? Or is it duplicated? Here it would just be a projection from 2d to 2d to 3d.

Could it be imagined that somehow we have infinite projections of 2d->2d->2d...?

That's an interesting question. My suspicion is that the information is imprinted on both as there's no apparent means or reason to have it change. However, I have to reference to post that says so.

I did find this article on Phys.org

That makes a lot of sense. There is spherical harmony to it too.
