the human body will encounter complications in low and zero gravity
ftl will never happen
space stations are a scam that rich tech ceo's promise
mars cannot be terraformed
life is probably unexceptional and we will never make contact with others
you will all die on earth
Anti space-doomer post.
FTL will never happen and that's ok. We can get around that.
Mars cannot be terraformed and that's ok. We didn't need it anyway.
It's worth considering that there are enough metals in this solar system to create enough 1G rotating cylinder habitats to provide more surface area to live on than all the habitable planets in the galaxy combined. If we just lived here in the solar system we could provide for trillions of humans.
At that point we could probably manage to gather enough energy fire some of them out to other solar systems. Give them enough fuel to slow down then just laser the fuckers in the direction of other stars.
Or heck it's possible to turn our own star into an engine by basically reflecting all the light in one direction and riding a beam of photons to get closer to other star systems over the course of a million years.
Legit if we started building some serious infrastructure in orbit around earth and the moon, I think people will be surprised what we are capable of.
Like a generation ship? Interesting concept, the only issue I see is getting access to all the metal in the solar system, it's a lot of metal. And then assembling it, although I assume you could put it together in space
The truth is that reality is stranger than science fiction, and when you look at non-FTL travel you start to think about pretty wild and massive concepts that are done on the scale of thousands or hundreds of thousands of years. Even without FTL, if you built enough generation ships around our star and then fired one to every single suitable star system in our galaxy at the same time, it would only take just over 100,000 years for all ships to arrive and for the galaxy to be colonised.
"Generation ship" really depends on how fast you shoot it out of the system. If it's going fast enough it's not a generation ship from the passengers perspective. They'll arrive in 100,000 years but for the passengers it could be less than a lifetime of subjective time, plus and on the scale of the universe, 100,000 years isn't a long time. Supposedly it 100,000 years for our ancestors to leave Africa and settle all corners of Earth.
It just means that without FTL we all become time travelers while in transit.
Don't need a generation ship if you solve old age (or accelerate fast enough to relativistic speeds)
Also dismantling Venus would get a decent Ringworld/Dyson swarm going. The Asteroids alone could vastly outstrip Earth's area.
