Just as you can compress mass in a spacial dimension, so too could you theoretically compress it within the temporal dimension.
Theorically...?

Time, recall, is merely another dimension by which space/time is measured, and while under most normal circumstances is inalterable, under extreme conditions, it can be alterred, though you really will only notice it if you are able to observe a difference in the passage from one area to the next.
Explain to me about "under extreme conditions" stuff.

Addendum: And yes, it is revolutionary, at least in the sense that it does nothing but go in circles.
I think he is not really good at english that's probably why.
He's probably wants to explain more detail about his theory but he just doesnt know how to say it.
