The Universe began all at once in a big fizzle of pure energy, not a big bang. What we know so far is that pure energy, or,"light", just started appearing. Some of that light formed tiny bundles called photons and then photons got tangled and we call those tangles "matter". Galaxies, stars, planets, moon, and life all come from energy bundled up as phtons tangled up into "matter". Photons that aren't tangled up as matter zoom fast (speed of light) and they keep going in a straight line unless something gets in their way or they get tangled up. From the beginning of the Universe, the "edge" of the Universe is simply where the farthest zooming photons have gotten to. What it expands out into is sort of beyond our comprehension right now. Scientists are learning that way out there, far from Earth, it's VERY strange with different Laws of physics than we know about. But, everything that is this Universe, even the spacetime fabric and you and I, are actually composed of that initial 3 second fizzle of energy. Here is a real image that we have recently made of the beginning of the Universe. AND, here also is a real recording of the noise of that first fizzle:

This is the radio static of that beginning fizzle:

Your question makes an assumption that there is a farthest galaxy. The universe may very well be closed. By that I mean that attempting to go farther and farther from where you start may result in you returning to where you started.
That being said if there truely were a farthest galaxy then there could not be any groups of stars farther away than the farthest galaxy since by definition a group of stars would be a galaxy.

absolute nothing but its what i think. if anyone could figure out whats beyond the galaxy wouldnt u think he would get a nobal prize already?

That all depends on the shape of the universe. At this point it's all conjecture.

no one REALLY knows people think they do and they make guesses and stuff but no one knows how far it goes or if there isn't other life or if theres not so yea no one knows for sure ....its a mystery!
