Comment: "Where information can be encoded on the surface of space, the universe could be a 2+1 hologram with two dimensions of space and one of time."
Response: The universe is NOT a mere hologram as that term is usually understood. A hologram is spatial and static, which would ultimately stop holographic cosmology dead in its tracks. The universe is a hological (self-dual) self-simulation.
(Explaining this over and over again is getting old, especially as the CTMU predates contemporary "holographic cosmology").
