Thanks for this - holography as a theory strikes me as an absurd math trick - if a 3d world is really just a 2d surface, would it not logically follow that said 2d surface is itself merely a projection from 1d, and perhaps that is a projection from 0d?

Obviously I don’t understand this, and probably won’t but what limits the dimension reduction?

Going the other way, would our 3d space not be the “surface” of a deeper 4d space, and that of a 5d space, etc?
