Yes. It is thought to be about the size of almost 0.0000000001 yoctometers.
Some would disagree and claim that time has no definite physical form, but exists only in the human mind (to be a creation of humans, not a law of our universe).
Time doesn't affect space. Space and time are the same thing in relativity; that's why we call it spacetime. Mass affects spacetime and spacetime affects mass.
It isn't. Gravity is a force created by mass in spacetime; the centre of the Earth is a particle of matter.
There is a very easy analogy for how gravity works. Everything in the universe takes place within spacetime. Imagine spacetime as a trampoline. Where mass exists, spacetime becomes curved, just like a trampoline would become curved if one were to place a bowling ball on it. We as people fall down the curves made in spacetime, but the earth keeps us from falling any further, thus we are stuck to its surface. If one were to put a ping-pong ball on the trampoline, it would fall down the curve made by the bowling ball. It would stop once it hit the bowling ball, and be stuck to its surface. There are a few subtleties to this model that keep it from working perfectly, but this is basically how gravity works.
Gravity is a force.I'm guessing that you're reading something about relativity, have run into the "curved spacetime" part, and are reading a little too much into it.
Holes.
Large mass (in astronomical terms) bend and distort the fabric of spacetime.
A planets gravity is caused by the distorting effect its mass has on the fabric of spacetime.
Because spacetime is not actually a fabric, nor is it a solid or liquid or gas that friction can be created with.
Look at this websitewww.spacetimemodel.com It says that mass is really just a 4d volume of spacetime displacing and therefore warping the spacetime around it and so the answer is all mass displaces and so warps spacetime.
There is no such thing as gravitational force. Mass curves spacetime and stuff moves through spacetime in straight spacetime paths. The effect of this is what we call gravity. The more the mass the greater the curvature of spacetime.
Time doesn't affect space. Space and time are the same thing in relativity; that's why we call it spacetime. Mass affects spacetime and spacetime affects mass.
Therefore they are consider matter. Remember anything with a mass is matter.
Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
Time is the distortion of the four dimensional spacetime fabric. The more distorted the fabric is, the slower time travels. Search Time Dilation for more information
Yes, the sun has much more mass than the earth so the sun warps spacetime much more than the earth warps spacetime. The amount that spacetime is warped by an object is proportional to the strength of that object's gravity.

Gravity does not escape, its not a thing, it is the warping of spacetime produced by mass. A black hole has lots of mass packed in a very tiny volume so it warps spacetime quite significantly, producing strong gravity around it.
