Saw this video about some surfer dude in Hawaii (another video, same lines) who is making the claim that reality is a simulation. Talks about some eight dimensional geometric crystal called E8 that converts to a 4D matrix/universe then a 3D universe/matrix for us observers. Now there was a ratio between 4D & 3D size wise and they called it the golden ratio (.618). Apparently this ratio is found elsewhere in mathematics/geometry or at least keeps popping up in calculations for various geometric shapes I think. Not sure and always skeptical about such things so I wonder if someone here could explain exactly what is meant by Golden Ratio, what it is exactly and if it really is something that should be taken seriously?
