The Collapse of Quantum Theory

The equations of quantum theory predict what happens during a double slit experiment. Photons are expected to strike everywhere possible, which makes a pattern like this. If we were in a single universe, and there were no other copies and no photons in other universes, we should expect the same point to be hit over and over again on the screen. That's what science tells us. But we don't get the same result, do we? Over time we see a pattern build up, which pattern is the very pattern that we would expect if we lived in a multiverse. This is the only known explanation of these observations. We've ruled out, refuted, any single universe theory.
