A planet where you can set up a city and not have to worry about micrometeoroids, radiation, atmospheric composition? Just sleep out under the stars without a suit repair kit handy?
That’s worth killing for!
- wasx 9y agoWiping earth clear of humans and still having a habitable planet left over would require far more resources, risk, lives of your own and time then simply building a few colonies on planets like Mars.
- swombat 9y agoPfft! Smart aliens just send a couple of stealth probes, figure out our biology, and in short order program a simple virus that is dormant but highly contagious for about a year and then when incubation is over kills within 24 hours. Ironically it’s not far off what was done to the Americas. War is only an option when the sides are more or less evenly matched. We would not be anywhere near evenly matched with an interstellar civilisation.
- XR0CSWV3h3kZWg 9y agoIf you can make the trip you can probably survive in space definitely. I'd be surprised if truly space faring civilizations really like gravity wells. Getting up and down them isn't cheap (although with plenty of effort it can be made cheaper). Everything is all stuck together, if you can find an asteroid of the material you want mining it and moving it for sale/manufacturing should be so much cheaper than dealing with moving a bunch of unrelated materials away under gravity. In space you'd be able to move arbitrarily large objects with just an accelerator, map of the solar system and a transponder. In a gravity well you need a lot more and way more $$$ if you want to get it up the well. Then again I have no training in the subject.
