Submitted for your consideration, something someone on weed once told me that I am in no position to say is true or not because I don't know enough about astronomy, but it's interesting to think about:
The celestial bodies of the universe are slowly drifting further and further apart. The longer we wait to colonize other planet, the less likely we will ever even be able to reach them. Additionally, planets that are currently uninhabitable due to being too close in proximity to their respective stars (eg Venus) will one day be more habitable because they will be farther away (Venus is a bad example because it's a gas planet). Likewise, planets that are currently habitable will eventually be too far away from their suns to continue being so.
Thoughts?

Actually no, that's not it, we're not getting further from the stars, it's galaxies that are drifting
I wish we had edit on this board sometimes

Yes, but this may take... what? 100 billion years? Maybe less, maybe more, we really have absolutely no idea. I think we've confirmed that certain planets in certain galaxies that orbit around multiple stars can become slingshotted into deep space though. Neil Tyson talks about this. He also explains how life as we know it can survive without a star as the only energy, and that earth actually generates energy from it's core still. One last point he made was there it's probably that there are life forms that are unimaginable to us, like the exist completely outside the boundaries of water and oxygen.
Anyway, not sure if that has anything to do with what you're saying but I thought it'd interesting nonetheless. I'm not astrophysicist.
