Do you think that space ever ends out there?

Yes, it does. We even know how wide the universe is (93 billion light years across, or roughly 961,554,801,903,307,093,931,196,416 yards, give or take the odd inch). Relativistic bending of space/time means that technically we're in a curved but finite universe however, so if you travelled far enough, you'd end up back where you started. Much like if you tried to walk to the edge of the Earth. Naturally, this would take a while, also.

Space is one of the main things in the universe that are infinate.
