What makes this whole thing interesting is the word "observable"
What else makes it interesting is the next thing:
Think about it.
If we were living on a for us unobservant flat surface seen from a higher dimension, this would mean that if we see a galaxy on the left side, we should be able to see it on the right side as well, UNLESS if space is expanding quicker than light can keep up, in that case, this would mean that a certain amount of the universe would be forever invisible to us, and that the more the universe expands, the more objects will fade from our vision until the whole universe becomes invisible to us...
Even in this scenario though, the universe does expand from one point, however, we may not be looking for the right point, but for a completely different point, from which you could practically reach every other point in the universe.
Think of it as a VERY quickly growing earth, as a man walks from A to B, he could possibly never reach it if earth expands it's surface faster than the man can walk, for him to reach that other point, he would have to dig himself into the ground, towards the center of the earth, and from the center he could move to his destination directly, unless this earth expands faster that way as well, in this case, our little dude will be doomed as soon as he enters the ground.
The fun thing about theoretical science is that it's like LEGO, you can do anything you want, there are no rules except that the bricks must fit and nothing must fall off on it's own.
I fucking love science.
