What is meant by Fabric of the Universe?

Is it possible for events to cause or create effects measurable at speeds greater than that of light?
For example:
Andromeda Galaxy is reportedly about 2.5 million light years away. What are the hypothetical possibilities relating to communication or travel in a shorter period of time?

Denim. But don't tell everyone.

I was under the impression it was black taffeta.

Yeah, but what does that mean?

@neologist,

Where did you hear that phrase "fabric of the universe"? Can you present it in the original context?

Should I have said fabric of the cosmos?
Sorry, I thought using a comparable word would bring more response

Life is meant to be one very long Levi's Jeans commercial. All good looking 20 somethings having feelings and such.

It means, Neo, about the whole 9 yards

But what does this have to do with the speed of light

Presumably a particle having mass is limited to velocity c though some "processes" are thought to go faster but they can't carry any info

Drat! I've been trying to lose enough weight to get back into my 38 38 501s. Now you say that's only for 20 somethings?

Wait?
Nine yards of denim? I was thinking of something more like the space-time continuum, curved space, and speculations such as that.

@neologist,

Brian Greene's mention of the Fabric of the Universe, is an analogy for a structural characteristic of space-time predicted by Einstein and demonstrated by the effect called Frame Dragging (which has been measured by gyroscopic satellites).

Is space bent or does it simply appear to be bent, depending on the observer?
Does time move more slowly, or does it simply appear to move more slowly, depending on the observer?
If you travel in a straight line indefinitely, will you eventually return to your origin?

No, it's cotton.

Mass warps space. This is demonstrated in many ways, but gravitational lensing is one observed phenomena which exactly matches predictions by General Relativity.

Clocks in a higher gravitational field show a change which exactly matches the changes predicted by General Relativity.

I don't know. I've lost track of which cosmological topology is currently on top of the probability list, but I think the most recent answer is "no" based on the accelerating expansion which was observed back in the late 90's.

Does speculation about the Higgs Field fit in anywhere here?

Not directly. The Higgs Field is supposed to be what gives energy (and matter) mass. The "Fabric" of the Universe is more of an analogy to a structural characteristic of space-time as represented by General Relativity.
