Thread: Inteplanetary age Jupiter colonization - Irregular satellites?
Post: Inteplanetary age Jupiter colonization - Irregular...
| I noticed that most EG articles focus mainly on the large moons of Jupiter. What about the small irregular satellites though? There's quite a lot of them, they would be easy to extract materials from ... |

Thread: Proxima Centauri b
Post: RE: Proxima Centauri b
| I think a significant factor for habitability would be how volcanically active it is, if we consider the snowball earth episodes.
If it is in a 3:2 or 5:2 resonance and was mostly covered by oceans... |

Thread: What would it take to break OA?
Post: RE: What would it take to break OA?
| Wormholes not working like they do in OA would likely change quite a lot. Either in the sense of Wormholes being proven impossible by some new theorem, or of wormholes allowing time travel. Time trave... |

Thread: Post scarcity: second order effects

Thread: Post scarcity: second order effects
Post: RE: Post scarcity: second order effects
| This is an interesting train of thought. For example, even if launch costs actually stayed as high as they are now, at 2% real GDP growth per capita we have 1.02^700 = 1 000 000. So in 700 years, we c... |
