Then I better understand what you meen, however, I still don't agree.
I say our universe is only one universe. Not one for every 'now' that hs been and will be, including the 'now' we're in right now.
I don't think that the future exist now, nor the past exist now. The future is there in our speculations and expactations, ie in our mind. The past is there in our memories, and evidence in the 'now' reality.
If we compare the Universe with a reel of a movie, say 'Gone by the wind'. In this film there is thousands of separate pictuers. If we look at one of them, calling it the 'now' picture. The picture ahead is the future and the ones we already have seen is the past. Here we don't agree. This is your parallell.
My parallell is that the only known picutre is the one we're looking at right now. The future pictures doesn't exist, and the past pictures are also 'gone by the wind'. Our Universe is only a snapshot of itself.
Who is right and who is wrong? That we cannot ever know for sure. But it is a very profound truth about the Universe.
If you are right, then time machines is possible, we can foretell the future, because the future is already known (by the universe itself at lesast), astrology works,a dn sush.
If I am right, there is no way time machines can work, there is no way to see into the future, asrology is not more but a religion. Sorry to say, my universe is a boring universe. But I have a free will, and that counts for much.
