Question	—	Antimatter filled buckyballs - The energy storage medium of the future Antimatter gets used a lot in SciFi due to it's mind-bending energy density. If you can store it in a form that requires no power and is at least mildly idiot-proof then you've just solved half of your space-civilisation's energy problems. However, all of our current technologies have a drawback, eit... (more)	—	about 4 years ago
Question	—	When I turn on my warp drive, where does the energy go? I've just bought myself a shiny new spaceship equipped with the latest in FTL warp technology, the only catch is the fuel bill, this thing drinks the stuff like it's going out of fashion (still, it's better than the F150 but that's another story). Now I'm just a humble space-cabbie but, my understan... (more)	—	over 5 years ago
Question	—	How to have people and big bugs at the same time There's been a few questions about making big bugs before and the consensus in they can't get much bigger than 3ft or so (which in reality is still huge). Catch is, you need quite a bit of extra oxygen to do it which doesn't bode well if someone wants to throw people into the mix... So,just how big ... (more)	—	over 5 years ago
Question	—	A structually self-supporting hollow Earth? Is it possible to have a structurally self-supporting hollow Earth where the weight of the shell is balanced against the atmospheric pressure inside? It must be human habitable (gravity is nice but optional) It must be able to keep its occupants safe from radiation from space.... It must be able to... (more)	—	about 6 years ago
Question	—	Probing neurons to map someones brain Could you map out all the connections in someones brain just by probing every neuron and tracking them as they send signals to each other (as opposed to every synapse, a much less ambiguous but far harder exercise) The technology level is 20 minutes into the future. We already have self-assembling d... (more)	—	over 6 years ago
Question	—	Engaging your warp drive while underwater There have been more than a few questions covering Alcubiere warp drives, many about what happens with one at FTL and a few about using them at sub-light speeds. I'm curious about what happens at more pedestrian speeds (tens to hundreds of kilometer per hour as opposed to percent light speed) If so... (more)	—	almost 7 years ago
Question	—	What are the energy requirements of moving some of Venus' atmosphere to Mars? Say we built two large scale portals and sent one to Venus and one to Mars much like in this question but with portals large enough that mass flow rates are not an issue seeing as nobody wants to wait around for 108 billion years for some more habitable planets. The idea is to dump some of Venus' at... (more)	—	almost 7 years ago
Question	—	Do space androids make big impact craters? Say that a heavy (150ish kg) android was involved in some kind of incident in orbit and came crashing back down to earth (traveling at orbital-ish speeds upon re-entry). Would they be going fast enough to "arrive" with a bang or would atmospheric drag have slowed them to more of an anticlimactic sof... (more)	—	over 7 years ago
