I saw some videos about the Holographic Universe and I found a big problem, has some people (non-physicists) that create videos saying the Holographic Universe is created by our brain (to hold religious beliefs), they say that people, objects, etc are made of waves and frequencies (sounds)...and translated by our brain in holographic projections, I know this is totally retarded, you guys know some way to get it out of my head? Any mathematical model that proves that this is a lie? because now I have difficulty accepting the solid matter, I keep thinking all the time that is my brain that creates a holographic projection. [I know that this is BS, like, how the camera works then? Or what my brain is made of if he is creating the holographic world around me? But I wanna know if there's a mathematical model that proves that's BS..
