Sorry 'bout posting so many topics but there are too many things that are unclear to me. CMBR measurements suggest the universe is pretty much FLAT, but I don't see it as flat, and forget our planet, all those vast spaces in every spacial dimension - all that is flat? It obviously has depth to it, thats observable, but measurements say otherwise. Now we all know about cinema, and most of us have been to a 3D cinema, where a flat projection creates a 3D illusion. I know the "projection" universe has very few supporters in the scientific community and is mostly new age conspiracy theorists talk, but if the so called reality is really a projection, wouldn't it make sense for us to observe as a three dimensional and expanding universe, in the case it is not projected on a stationary screen, but more like a event horizon that travels at the speed of light?
