Reply to comment by blscratch in Whats stopping us from sending a probe into a black hole if we haven't already? by stealth941

The holographic principle is a thing. There are hypothetical descriptions of a black hole that say all of the information about the particles that entered the event horizon is spread out on a 2-D layer around the event horizon.

This math could be extrapolated to show that all of our reality is a projection onto the surface of a higher dimensional universe.

There is no proof for this. It is only a mathematical description of one of the ways our universe might look from some higher dimensional perspective. As far as I'm aware, it is based on sound science, but that doesn't mean it is true.

PBS Spacetime on YouTube did a whole series of videos on this.
