BHIP is a theory that discusses how when information in the form of particles goes past the event horizon, there is a possibility that the information is destroyed. This is problematic is because if this paradox is true, then everything we know about physics is wrong.
However, there are several solutions to the paradox. One of these solutions is that information could be projected on the surface of the black hole. This gives way for simulation theories to come because if 3D particles could be projected onto a 2D surface, it means we could be living in a Hologram.
That is a LOT to take in...
