We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Near enough to be relatively confident in how much we won't progress in terms of colonizing space. The general public severely underestimates the limits to space travel & survival. It's not like I can tell you exactly what or when technology will be like in some exact point in the future, but it'd probably be a few hundred years until we could actually make nation-sized space colonies, and there's pretty much no future where space habitation replaces or becomes greater than Earth habitation, unless we go ahead thousands if years. There were a few interesting astrophysics papers estimating that near-lightspeed and FTL travel tech is like 8000 years away lol.

"Future technology" can't solve all of our problems. It's not magic.

76 years ago was 13 years before Yuri Gagarin would become the first human in space. It was 4 years after the V2 rocket became the first artificial object to enter space. This is plenty of time for multiple technological revolutions to happen. We're already on the verge of one with fully reusable superheavy lift rockets, most people don't grasp just how big a change will come from having that sort of cheap bulk cargo access to space.

There's no need to make nation-sized space colonies, just make lots of smaller ones.

I would like to see those papers. Making technological estimates on that scale, especially for something like FTL that has no physics backing it at all, is highly dubious.

There's no need for magic, this is really just a question of economics.
