So I've been looking up the holographic principle for a while and I'm having trouble understanding somthing that I feel is obvious that I'm missing. I understand that a volume of space will have the same information as it's surface area, but is it the same information? What I mean is if I drop Alice into a black hole, from her view inside the black hole she will see everything 3-dimensionally. Bob, who is outside of the black hole, will see Alice's information 2-dimensionally on the event horizon.
The part I'm having trouble with is are they looking at the same Alice? Is the Alice on the inside a clone of the one on the surface, or is she in a sense in both places at the same time?
If you couldn't tell I'm a layperson so please keep answers simple. Thank you.
