  1. Expansion is not constant. It has changed a lot between the big bang and now.
  2. Expansion depends on the amount of space there is, more space equals more expansion
  3. This is called the big rip. I'm not certain what the current state of research is regarding that. But it won't happen for many billions of years.

First, a self sustaining colony is not automatically the same as a colony. Second, disregarding unlikely extinction events, and focusing on likely extinction events, it would make much more sense to finally do something about climate change.

It makes no sense to colonize the moon, there is nothing there we need. And even if, costs are much higher than getting it on earth. Colonizing Mars is just a fever dream of a mad man. Unfortunately the richest mad man on earth.

According to some paper I skimmed, we are squarely in the middle of the best time to be in a habitable universe.

"Based on the evolution of the global star formation rate, the CHA encompasses at least the last3.5 Gyrs (the time since the origin of life on Earth) and probably the last 5 Gyrs and the next 10Gyrs. "
