not necessarily just the galaxies, wouldn't the limited speed of light mean we can never reach the edge, especially with expansion having a huge headstart.

Space is not expanding. The distance between the known planets, stars, and galaxies is expanding.
We will never reach the edge of infinity no matter how fast we go.

Given your assumptions, yes. But from what I know about space, there's no reason to believe that an 'edge' of space exists. What is rather happening is that each bit of space is getting larger as time passes, for a net result that any large volume of space (say, the volume between the Milky Way and Andromeda galaxies) seems to expand.

There is no edge. The universe is finite but unbounded, like the surface of a sphere. Imagine that sphere growing larger and larger. Spots on the surface get farther apart, but there is no edge or center (remember we're talking about the surface only). So it is with the cosmos. Space expands, objects grow farther apart, but there is no edge.

Not necessarily. Einstein's general theory of relativity combined space and time into spacetime and made time travel a theoretical possibility. The mathematics describing black holes shows that they have two ends or openings and are tunnels through spacetime.

i have no idea what the universe becomes at the end, if it has an end/egde, or so i cant really answer it, except travel twice as fast as the speed of light and we would eventurly catch up
