what's the best guess as to why space is expanding? Dark energy is just other dimensions "pushing" on us. String theory says there must be 11 dimensions for the math to work.

Empty space has neither mass (the trivial virtual particles count for nothing here) nor velocity thus no momentum.
You are taking complete gibberish yet again.

That explains 'how we know' but somehow I don't think that was the kind of "why" he meant.
I personally don't have the necessary expert knowledge to even come close to adequately answering what I assume was his intended meaning of his question.

Not only that, it explains the how of how it's happening.

In my mind, I envision creation as the drop of the stone into a pond, with the effect of rippling outward.
I believe what we "see" are the reverberations of that splash, somewhat akin to the diminishing vibrations of a cymbal crash.

how is empty space expanding?
