Yeah, I could have worded that better. Let me try again. According to the holographic principle the surface area that surrounds a volume of space should contain the same information that the volume has. So if I have Alice inside a 3D space, that same information should be on the surface area that surrounds her. http://m.dummies.com/how-to/content/string-theory-insight-from-the-holographic-princip.html So would that mean that there are 2 Alices, or is she both on the surface and in the volume?

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.
