Most people are unable to realize distances in space. Humans are simply not designed to travel in space. For a space ship that can be self-sustaining in every way and capable of multi-year travel, it has to be almost like a city. Even when you get to planets, they are even less hospitable than Mars. I think future life forms which will colonize other planets will be machines, not humans.

It's quite easy for a person to look at two galaxies in a telescope that will never be able to even observe each other's existence, let alone visit one another. People often argue that we'll find a way to travel faster than light -- which is curious given how rarely people argue that we'll find a way to travel backwards in time.
