My english teacher (we talk about everything in english class) said that the universe, without a doubt, would continue expanding forever. I remember reading in a book tho that there were several theories about this and none was for certain and they depended on the density of the universe which hasn't been found.
I also read in another place that the universe wasn't really expanding, the distances were just stretching.So my question is how does gravity affect this if galaxies aren't actually moving away.
