In the madelbrot set, you can zoom into any part of the pattern and it repeats infinitely. This can be seen in nature… in trees, how branches form, into smaller branches, into leaves… and on the leaves, the veins are visually like the branches, but smaller. In a way, even within our reality, there are parallel realities, existing in the form of nature, art, beliefs, concepts. I think the universe is a multidimensional mandelbrot sequence.

So, coming back to why the theory of membranes colliding to create the big bang doesn’t make sense to me…. is because I can’t see that concept being reflected in anything else. I’m sure, it makes sense mathematically… but I’m just a layman. If a theory is sound, it should make sense on all levels… it should be reflected in art, science, nature, etc. Maybe I don’t see it. Maybe it’s just me… but this is why I think their theory is not the best explanation.

You say the history still exists in our past and we might be able to experience it again if we traveled back in time, and altering the past would make parallel dimensions? I find the other parts credible, but if you claim there already are parallel dimensions, then someone in some, probably the original dimension if you like, has discovered how to travel back in time. But that theory itself has a… problem. What if someone from the future travels back in order to undo the events that led to inventing the time machine? What would happen to the possible parallel universes that were created due to previous time travels?

So, the events of history stay despite of moving forwards, and those events that are floating in time in a manner of speaking, shift over time. Like sand moving on a windy hill, over time. It’s like a fifth dimension in itself, a dimension related to time, but like another dimension in same manner as horizontal dimension is another dimension of space to vertical, and depth is the third. Well, if you’re correct in that the events of time stay there, which they might since they’ve already existed although I don’t know any way to confirm it, then I see you’d have a very good case here.
