is there is a end of space? what is the shape of space is it like a balloon ? what is happening out of?

Answer 1

You will never know because if you could travel at a billion times the speed of light, you would never reach the end. It is called, "infinity".

Answer 2

You have found one of science's greatest mysteries. It is speculated that space occupies much of the universe, which is spherical; if you were to start flying through space in any direction and in a straight line, you would eventually return to your starting point.
We have no information about what is happening beyond the Universe. Some speculate the existance of a 'multiverse', itself infinitely large and containing an infinite number of universes. Others speculate that outside of the universe is where the supernatural lies.

Answer 3

Your question boggles the mind. There is no end to space or creation. Think, if you will of the atoms of iron in a iron bar. They are densely packed but still moving, granted slower than other atoms but the atom is not very different from our solar system, and for our knowledge, our solar system could be similar to a simple atom of iron, and we would be a meson or one of the other lesser subatomic particles. The term infinity (meaning without end) is very fitting for space.
