we all, even Einstein say that space time is a fabric in which its curvature due to the mass is the gravity. Ya, I know that, but in reality, is this 'fabric system' possible? Because the real space is 3 dimensional and how could be space along with the time be a fabric of 2 dimesions?

AFAIK spacetime is 4 dimensional, 3 spatial and 1 temporal.

Those little nets with indentations you see are just over-simplified mathematical models. In reality it's a little bit more complex, why is why you have things like string theory. We don't know exactly why it's possible, some people are trying to prove there is a Higg's boson which is supposedly the particle that causes mass, and it seems like proving that might conflict with the model of a gravitational well, but gravity will be gravity no matter what system is describing it, as long as all the end results are equal for all models describing it.

but i think that the curve of gravity in space time fabric would be the contraction of space in and time in reality.
