What have just said makes hardly any sense at all. I won't trust everything you read on Google anyway. Can you send a reference to a published article?
I think you are mistaken...
I'm sorry, but I don't know where you've got this idea from so I don't know where your errors have arisen from. There are no galaxies moving faster than light, nothing can travel faster than light in any comparison of velocities.
Since no galaxy can be moving...
The theory of general relativity explains gravity incredibly well and experiments back this up. There is a small amount of observational data that disagrees with our current understanding (such as the rate of deceleration of space probes in the outer solar system), but there are many other...
Where did you get this idea from? I think you are quite mistaken here. If you are not traveling faster (colinearly) than the object you are pursuing, you will never catch it up. So if the "slow" spaceship is traveling slower than the galaxy (which is what you implying), it will never catch it up.
The reason why we can't see galaxies beyond the observable edge of the Universe is because the light from them hasn't had time to reach us. Quite simply, speed of light = distance to edge of observable universe / time universe has existed for.
Also, someone mentioned earlier that velocities...
