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 ...

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 l...

I could imagine some clever pranks as well. Like giving an emperor _actual_ invisible clothes. Or using clarketech to double the size of a modo's flat without changing exterior dimensions. Or hollowin...

Post: Using a laser pointer to confuse a kitten

So, while using a laser pointer to confuse my cat, I've been thinking. Some transapients would clearly find it just as adorable to see modos or lesser transapients thoroughly confused by something tha...

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...

A while ago, I stumbled upon a simple but fairly useful result, which I felt that people here may be interested in. For a variable Isp rocket running at constant power and constant acceleration, the ...

Post: RE: Post scarcity: second order effects

The "real" in "real GDP growth" means inflation is already accounted for. Scarce things like well-situated land stay expensive since they are scarce. Manufactured goods such as say cars, ships, or co...

    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...

It depends on how much infrastructure you assume. Tethers become a very strong option especially when you consider using them in less explored ways such as sliding along them. I'm thinking along the l...

It would cancel out the 4.92 ratio. For large delta-v's The ratio is shifted towards absoultely humongous amounts of reaction mass, which you have to cut off at some point in a practical design by usi...

The MR = ~4.92 optimum has a number of assumptions behind it. I derived it myself a while ago on NSF after a discussion on hafnium nuclear batteries and the like. The basic assumptions are: 1) dry ma...

I don't think you'd need any fancy vaccum baloon technology all that much either. A helium filled baloon needs a mass of helium equal to roughly 14% of the mass lifted. Though if you want to give a la...
