Ok, be advised that one course does not a physicist/astronomer me make.
1st of all, the edge of the universe. You cannot reach the end of the universe because by the very virture of you being there, you're expanding space.
2nd, since mass do warp space, then all that mass within the universe curves space.
3rd, time. Now this is somewhat harder to explain. Time is an event. In order for time to exist, something must happen and since light is the fastest thing in the universe, we equate time and light to be same thing. In order for time to start existing, light must have had to occurred. Where light has not gone, there is no time ... because nothing has happened yet.
This will also help explain why some parts of the universe is 18 billions year while others are 12 billions year old ... because light traveled longer in that direction than in the other.
To help explain this, if a tree fell in the forest and you did not see it, has the tree fallen. Well, to you, it has not because you've not seen evidence of it.
BTW, this is still all Einsteinian explanations, not quantum mechanics.
