According to Hubble all the galaxies, which are composed of billions of stars, are running away at tremendous speed (including our Milkyway galaxy) and the speed is increasing! At what point of space they will stop?

They will never stop. The galaxy is expanding outward and always will be because the universe is infinite.

There are two schools of thought, but both agree that (a) the galaxies APPEAR to be moving away (b) there is no outer limit to space (c) there may well be many other universes derived from their own big bangs; the difference of opinion lies in whether the gravitational force is just that teeny weeny bit too weak ever to slow down the outward motion, in which case it will go on for ever (whatever that means), or is just barely strong enough to do the slow-down trick, resulting some billions of years hence in a "big crunch". So there!

Since the Big Bang 14+ billion years ago, the universe has been expanding. Think of the galaxies as spots on the surface of a balloon. As the balloon expands the spots move away from each other. As you rightly say, this expansion Is accelerating. When this expansion will stop is one of the great answered questions of cosmology.

Galaxy are running away and universe is expanding. The effect of big bang is still going on and universe is expanding. When the effect is completed, it will stop and all stars are approaches at their life end position and completely burnt out, it will coolify and start shrinking and energy will regain through contraction and temperature will rise and a new big bang will occur.

The galaxies are always moving away from each other. Ever since the big bang space time has been expanding in every direction at every point.

This is a hotly debate issue. I believe that the planets and stars will slow down as the lose energy untill they stop, then the gravitational pull of the planets and stars will pull everything in into the 'big crunch', when this happens is hard to tell but it will be a very long way away

You said it yourself: they speed is increasing. They won't stop. They will keep flying further and further apart, until the Universe is an unimaginably lonely place.

String theory suggests that, trillions of years from now when the Universe is a very cold and lonely place, a new Big Bang may occur and spawn a new universe.

What goes around, comes around.
I think that two galexies will go round in a giant circle and eventually crash into each other. Life is a cycle and a circle. So therefore is the way space forms and finishes.
By the way it will all happen on the 31st of September this year.

If it is indeed an explosion, it will eventually stop and start going back together. Since engergy is never lost, there is a opposite force as in every explosion. In a vacuum, masses are attracted to one another just like when two big ships run close to one another. It's Einstien's rubber sheet theory to explain Newton's law of gravity.

I thought the galaxy's were moving closer together (or they could be staying still) but space it's self will continue to expand as light continues to travel. I cant back this with any facts i just heard it somewhere.

They aren't running away from eachother, the fabric of space between them is simply expanding in all directions. If I remember right, it will stop at the "big crunch," which is like the opposite of the big bang. I'm not sure about that last part tho...
