What is space fabric made out of?

Answer 1

Space is not made of anything. The fabric description is just an analogy to illutrate the point that space can warp and bend like a fabric.

The fact is also that we really don't know much about space. We currently aren't even sure how many spatial dimensions of space there really is. We think it is more than 3, but we won't know for sure, or how many, until we perform some very high energy particle accelerator experiments (may have results in the next 5 years).

There are somethings that we do know about space:

(1) It is capable of expanding or growing exponentially, and has been doing so continously for the last 14 billion years since the Big Bang.
(2) It can be warped by matter and energy - the more massive the object, the more warping. Blackholes are the extreme example where space is so warped that it may be ripped.
(3) Space is NOT empty. First there is what's called vacuum energy, that is empty space itself has some energy. This vacuum energy is also what's responsible for the accelerating expansion of the Universe.
(4) Quantum mechanics tells us that in empty space at very short distance scales (10^-33 cm or less) and very short time scales, particle-antiparticles are created and destroyed constantly. This is called the quantum foam, meaning that space is actually not smooth. It is frothy or foaming like a sponge or bubbles.

Answer 2

You need to know that the pathitic, 4 dimensions of space,
X Y Z and time that we now use are part of 11 dimensions,
7 of which we are " mostly " ignorant of.

You shuld search
ED Witten
M Theory
String theory
CERN Large Hadride Collider

We live on a SLICE of the real universe, like a slice of bread. There are infinite unverses on slices on both sides ( in 11 dimensions )

The only living person experimenting in the real 11 dimensions is
John Hutchinson - search Hutchinson Effect

Einstien died before solving the unifying theory that Ed Witten
et al are working on. The LHC experiments will verify the theory.
Very exciting stuff. Until then, the primitive view of the fabric of
the Universe is flawed and silly.

Answer 3

I wrote this on a thread that asked if black holes were real and stuff about how it affects space.

We really dont know anything about space.. As far as we know, our sensor technology could be primitive. Its possible we might need much more sophisticated equipment to figure out things out there.

[[One theory that cannot be confirmed nor denied is that space as we know it is a plane, or fabric. We have all seen gravity diagrams of the earth sitting on this grid of space fabric and its sinking down into it which creates its gravity. another idea is that beneath our "time" or fabric is another layer. There could be several layers. Taking a starship out to the edge of space may set you on the plane below, or above. You would continue to cruise forward with no change in pitch or yaw, save for measurements giving some strange readings.

The plane above or below would indeed be a different dimension of the exact same area of space. Same planets, same bodies. Those bodies would co-exist on every plane (lets say 3 layers of space fabric). But there could be aliens, or another species, or humans on the plane below. Why?

It would be because of the vast amount of time required to travel from our spot in space, around the bend of the edge of the universe, and back to our exact spot, but on the plane below. If you think about it, Two or 3 different beings could be existing on earth. That MIGHT have something to do with sightings and supposed ghosts and whatever you want to believe in. BUT, we wouldnt know what was happening on the other plane at all, absolutely zero communication.

But.. if you had an engine that could tear a hole in space, you could pop into the other plane without the travel time. You WOULD then be in another dimension of TIME, and possibly matter. Same space physics would apply. Same fabric, just a different plane.

Most hyperspace engines in the sci-fi world, just slice a thin layer of the fabric of space up, and the ship enters its "skin". Space supposedly being indefinite, at least to us, the ship would snap into an extremely high velocity that you cannot control. Other engine ideas "jump" you from one point to another, instantaneously. The engine would punch a hole in space where you are, and where you need to go, say a 30 light year distance max, and pop, out you go.

A wormhole could be a portal to the next plane, or it may be punching through all layers of space fabric, if any. Then you would end up as nothing, or below the planes of space, which would be impossible. Everything that exists must exist on one plane or another.]]

Answer 4

That is still an unknown question. A book a highly recommend reading is called "The Fabric of the Cosmos" by Brian Greene.

While some of it might be hard to read, he really does a good job of explaining the wild theories without requiring you to become a mathmatician. He and Dr. Tyson are probably the best sources for understanding high level physics without having to become one yourself.

Answer 5

There is no fabric. It is an empty space with some derbies.

Answer 6

coton fiber.

seriously: it's a metaphore.
