That is not how inflation works at all. It's just a rapidly expanding universe shortly after the big bang for a brief interval. A full explanation of it is far beyond what I can type on here during my morning commute, but suffice to say for he present context that I've never heard any cosmologist, astrophysicist or field theorist describe it as "warp" in any way shape or form, or suggest it can be used as a way of travelling faster.Warp speed is used by cosmologists to explain "inflation" in the the first second of the Big Bang. Otherwise the whole theory doesn't work. So I assume it's real. By "warp" it means it warps space-time itself which is allowed. We are not traveling in space-time but stretching it somehow. I understand that if you go faster than light this way, you don't have the the time reversal. So say warp111 +/- , x c to get there in a few hours. If you think that's crazy, cosmic inflation was almost instantaneous if you accept the theory which most cosmologists do.
