Is our universe a hologram?

Question

Probably not, but a hypothesis along these lines has been suggested.

There are two variations of this idea: 1) that the universe is giant hologram related to black holes and multiple universe, and 2) that the universe is giant computer simulation being run by aliens.

The reasoning for the second variant goes something like this...if we humans can create a simple computer simulation. like SimCity or 2nd life, then why couldn't/wouldn't vastly superior aliens create an even more sophisticated version, ie. our world as a sim?

Most physicists are very skeptical of either of these variations as there is very little to no evidence for these ideas. See:

undefined The idea that our universe could be a hologram is a theoretical concept proposed by some physicists. It suggests that all the information about our three-dimensional universe could be encoded on a two-dimensional surface. This hypothesis originates from certain theories in quantum physics and attempts to reconcile inconsistencies between general relativity and quantum mechanics. However, it's important to note that this idea is still highly theoretical and has not been conclusively proven. It remains an area of active research and debate in theoretical physics.
