It's possible that the past no longer exists, and all we have is the ever-present movement and happenings of the universe. It's possible that it's always been like that, the mechanisms and gears of the universe turning away. Whatever was before the Big Bang (unless something can come from absolute nothing. By that I mean no physical laws, mechanism, causality, or potential for anything to happen. Intuitively it doesn't make sense for anything to be able to arise from nothing, if it can then it's not coming from nothing).

It's a common misconception that we have evidence that there wasn't any 'before' The Big Bang. What's actually true is that we think we can never know, so thinking about a 'before' isn't useful when it comes to science.

Unless you have a good reason to believe something can arise form -absolute nothing- (no zero point energy, no space/time, no physical laws, no fields, no quantum foam, no pre existing supernatural energy etc) then once you've eliminated the impossible, you're left with there being a 'before' the Big Bang. That it wasn't the creation of all that is, merely pre-existing physics at work that provided the materials to fuel it, and the laws to guide how it happened.

You have no evidence the past exists. Only memories that you can access in the present that you can take as evidence it did happen, unless they're false memories.

If there are a finite number of states (although incredibly numerous) the universe can be in for a given area of space, then the past is in our future. The area of space we're in, or the entire universe, will eventually return to a state it's been in previously.

So those moments in the past are in our future as well. Given an infinite string of events stretching before us, and an infinite number of times the universe has been in this exact configuration (i.e. This second I'm typing) any state like that is neither in the past or the present. The state is timeless.

e.g. ("..." represents an infinite string of states which eventually repeat. And "The Present" is whatever state of the universe you travel to or focus your consciousness on as a God)

... The Present ...

So time travel to you as a god would be like flipping through a book with a lot of pages. There are a limited number of unique pages, or states/times you can go to and all of them take into account any way you could interfere with the state and how it would affect future states, in addition to all the interfering you've ever done in the infinite past etc.

I wonder if it makes sense that you could manifest yourself twice at the exact same state of the universe, it would depend on the mechanisms that underlie how you work as a god.

If you arrange matter, energy, and all the working parts of reality there are in a configuration they've been in in 'the past', that's identical to travelling in time. There is nothing else that exists apart from you and that configuration of reality.

It's just you and a massive Rubik's Cube that you're turning to form different states the universe can be in. If you interfere with one of those states, no matter what you do, you're just changing the configuration of the massive Rubicks Cube.

That's your future, just you and those finite number of states everything that exists can be in. Finite, but unimaginable numerous since the states are everything that's possible to happen.

I'd say that we can never obtain evidence that this is true, but could assume that any alternative is impossible. We'd have no guarantee that assumption was correct, even if we couldn't think of a reason why.

It could be that there are an infinite number of states the universe/reality can be in, and that every state that's happened can be travelled back to, and that every time a consciousness does this is changes all the states that are in that past's future, erasing infinite consciousnesses from reality and replacing them with new ones with different pasts.

​

If this doesn't make sense, in my defence I've been awake for too long without sleep. But in this sleep deprives state, it makes perfect sense to me that reality must always have existed in some form, and that it's possible that for an area as big as our visible universe there are a finite number of states it can be in.
