The Universe Is Stupendously Larger Than What We Think

The universe is stupendously larger than what we think. This is why we call it a multiverse, because there are other universes which are parallel to our own. They don't interact very often, except through these interference experiments. So this, what would otherwise might be turned an insignificant observation of the movement of single photons, leads to this stupendous conclusion that we live in a multiverse. David writes: "It may seem somehow out of proportion unfair even that such momentous consequences can flow from the fact that a tiny spot of light should be here rather than there"
