Oh, I am absolutely serious. It is something of a reference to "A Wrinkle in Time" by Madeleine l'Engle, wherein a character described a means of jumping through space by "wrinkling" the time fabric (called "tessarects" in the book).
However, recent physics research, including the fact that we picked up on the "sound" of two black holes colliding, is further strengthening the idea that there is some sort of medium (or "fabric") that could carry the (gravitational) waves generated by the collision.
You also have to understand, I'm one of those weird people that doesn't see time as linear, but rather as composed of the higher dimensions (above third).
So, in short, to jump space, you have to use time.
Ergo, temporal fabric.
I was going a little more mundane than that. For example local stars or other phenomena producing low-level energy fields (e.g. magnetic, electrical, something-undiscovered) that we could use for sub-light travel in a similar fashion to mag-lev trains. For example, the research on spacetime compression seems to fit about what I would expect (and also a temporal fabric). But I have my doubts about that specific theory.
Honestly, I think we can agree. I think temporal fabric is the medium needed, but the technology necessary to act on it would require us to actually work/build/design in higher dimensions, which may not actually be possible for us to do. (If you think about it, you can only move in as many dimensions as you can directly perceive.)
But then again, we never thought we'd fly, so we shall see.
My thought is, for that to even be possible, we need to figure out how to create artificial gravity fields, as that is clearly a force acting within the temporal fabric.
