Galaxies are not evenly distributed in space. Instead, when you look at the universe, galaxies are grouped in giant strings that look like a neural connections in a brain.
It blew my mind when I learned that we're in a relatively dark, empty part of space compared to what's out there. It really put into perspective for me how difficult space travel will be for us as we continue to advance.
Space is incomprehensibly big and its getting larger over time. We will never have meaningful travel outside the solar system. If humanity started traveling in space from the moment we evolved, we would be able to travel the length of the milky way around two times. Space is basically a boondoggle. Our solar system still contains lots of resources though, so its not totally worthless.
Yea ... like Star Trek, with warp speed and everything, is basically all limited to our single Galaxy ... and that's not unrealistic given their technology.
Like in that space-faring future, the galaxy is basically the new continent and the inter-galactic divide the new great ocean that no one has ever crossed.

Yea because gra-- woahhh
And here's the other thing I try to visualize:
Matter - both dark and "normal" - falling like water into these gravitational canyons that we see as giant strings, while the empty spaces in between expand and accelerate. The dynamics of this thing are mind-breaking.
