I voted "undecided". Before I ever heard of the Big Bang theory, or at least understood it, I believed that the universe (the physical allowance of displacement) was infinite.

However, after understanding the big bang theory, it gave me a possible reason as to why time seems to move forward, it could be being pushed along with the spatial dimensions, however, I don't know. I am undecided.

Excellent work by the way OP (opening poster). You seem to have spent a good deal of time composing your theory and wording your post. And also, the spoiler usage was interesting and noble.
