I just watched something the other day, believe it was on Science channel, discussing the Universe as a hologram theory...
The math behind it, seems to answer the dark matter problem, in that there is no such thing, the “extra” gravity is simply a matter of how we perceive the hologram. It also appears to unify (at least at the mathematical level) quantum and newtonian physics.
Obviously the whole explanation was dumbed down so a simpleton like me could follow it, but it appears as more and more people are theorizing and exploring this theory the more and more sound it seems to be becoming.
It even can explain the “loss” of information when matter enters a black whole... and while I admit I didn’t grasp all of it, it seems to imply that entire holographic universes could exist inside a black hole, and you could extrapolate from that, that our universe may be the inside of a black whole of another universe.
No wonder Physics grad students all smoke pot.... The stuff they come up with is mind bending.
