Remember: Infinite growth is not sustainable in any natural system
It is once we become a space faring civilization. For the next couple million years at least. Well, not infinite, but certainly exponential.
The lightcage (limit of speed of light travel) will kick in faster than you would expect. I believe it is less than 1000 years at current growth rates. It's like compound interest.
We’re unable to create a self-sustaining biome on this planet. There’s nothing about space that will make that task easier.
I think given enough time humans can solve almost any problem. We're quite innovative overall.
Space faring 😂 we are more likely do destroy ourselves and everyone on this planet than we are to ever leave our planet. Nevermind the solar system.
I appreciate the concern, and I think it's good to have awareness of a possible future like that, but that's a sad perspective to have.
I'm not saying we will destroy ourselves, I'm just saying given how unfathomably large space is, that even if we could travel at the speed of light... We'd be going nowhere.
Even if we never find a way around the speed of light limitation, and even if we never figure out how to terraform planets, the amount of resources in our solar system is vast and there's still a great opportunity for expansion with O'Neill colonies.
Obviously that requires very futuristic tech and will not be happening for a very, very long time. Still, it's worth working towards because I believe expansion and exploration is in our DNA. We just need to know when we've hit our limit for a given environment and not live beyond our means.
