Q: When I think of the steps to settling space, I think of it mostly in terms of technology and economics. If you don’t need to be economically self-sustaining, we’ve had the technology to build a moon base for decades – just spend $100k/kg on food and other things to sustain it that we don’t have … More Moon, space, profit, strategy, Q/A
Q: I read your article “How can I move a planet?” the other day. I’m not sure I understood the device, is it some kind of GIGANTIC mechanical arm that stores elastic energy to harvest matter? no, it isn’t a big mechanical arm, kinda. youtube links there are important to watch. all in the article is actually a fluff, … More Smart matter, clarification, Q1
It is a response to a conversation on FB, and the conversation will be below. Main four points are as a premise. 1>At that point a major war can break out because you need resources that are controlled by someone else. 2> But the global economy is no more there. 3> You can’t wait for … More Relations between Earth economics, Space economics, response to a discussion.
Ok, I got a valid question about what you gonna do with all those presumably available K1(10^18W) energy, in terms of production in space, which I have broadened to activity in space. If you do consider that the improvement of technologies is not required to meaningfully utilize the energy. It is a lot of energy … More K1 energy budget. Is it too much for us?
From a perspective, you may never be thought about. Originally it was posted as an answer to a question of WorldBuilding site. Where a guy tried to imagine a realistic space combat based on the tech he thinks is realistic. As with many of such attempts, A good answer can’t be given because strategy and … More A story about Space War and Space Politics in the solar system, you never heard of.
They have the destination, they heading to Supermassive black hole. reasons are TLTR, if short it allows to overcome some growth problems for a more extended period of time and have a bigger population as result. At the moment, this is the only place I know, where is possible to extract energy more efficiently than with any … More Why would a civilization choose to inhabit a single enormous vessel instead of maintaining interstellar colonies?
What is given? Humans have a practical problem, they need living space. But for how many? How fast population grows? As for the first question, some believe that for Earth 1 billion (109109) people is ok, and what is above is excess, there are bunch other believers. But solving the problem is to solve the … More What would come first, the colonization of the solar system or interstellar colonization?
Or rather how a tool capable of moving the planets can be done. TL;DR Build a planet big spaceship, move stuff with the gravity of that ship, using star energy for propulsion solar sail like. Or by pressing on the planet by a huge shell. As reasons to move planet are not given, so are not … More How can I move a planet?
(source) There probably no such place as the best for any task. It is a matter of preferences accordingly to chosen technologies for the building and other maybe even not related to technologies factors. I mean it depends; different factor and the place comes with the how and maybe why you do the building of … More Optimal position for an orbital dockyard
