What are the reasons for needing to spread humans about?
- overpopulation on Earth
- Earth becomes too polluted
- to survive a single extinction event (asteroid, supervolano etc)
- to harvest minerals
If we have the technology to travel multiple light years, with ships carrying enough people to start a new civilisation (1,000 people? 10,000? 100,000? 1,000,000? 1,000,000,000?), terraform another planet and survive there, then we will definitely have the technology to mitigate all of the reasons for having to make the trip in the first place.
The only real reason we'll have is just to explore, which probably won't be enough of an incentive for the people putting the money up to fund the expedition.
I dunno, maeks u fink i gess x
That list is fun to think about.
Currently Earth won't be over populated. Watched a video the other day where they said the child birth stats have flattened off.
Tech can save over pollution. We probably could at the moment, if people truly got behind it.
Extinction event would be a good contender.
Possibly minerals.
I heard that the sun in the system being talked about will last
a lot longer than our sun.
That could be motivation to move, but no one will worry about that for quite a while.
