Some thoughts on Time
What if Time is not *a* dimension as Einstein says, but a series of very short dimensions? As in multiversal dimensions. Each moment being a new static universe, the series becoming a changing dynamic series not unlike a film reel. We could not see this, since we are a part of each one. So time could just be the progression of new dimensions, all of which are already there, static. All possibilities exist "out there" but our consciousness seems to us to pass through them one by one.
So perhaps we can change directions in time much as we can in space, if each new moment we experience is selected somehow from all of the many mathematically possible "next moments." This seems to me to be a natural conclusion from the "many worlds" theory that I realize many physicists do not favor. Perhaps if we do nothing, the "next moment universe" we experience is the one most probable given the mathematics of the present moment. If we change those odds somehow, perhaps we can select a different already-existing "next moment" universe, or rather a different series of them moving forward.
For this to be true, I think the nature of this very complex multiverse needs to be mathematical and not material. We perceive it as material because we are also mathematical in nature, of course. Similar to Max Tegmark's pet idea.
