Question Restricted Directions for an Alcubierre Drive?
It's my understanding that if an Alcubierre drive were to be constructed, it would be able to function as a time machine because there would be certain paths through you could take to get to a destination which would result in you arriving before you started. It is, however, also my understanding th...

Question Would Alcubierre Drive Technology Allow for Artificial Event Horizons?
So, my understanding of how Alcubierre drives would theoretically work is not particularly complete. I know it involves compressing and expanding space, but I don't really have an intuitive grasp on what that means. So, if you have the technology to create an Alcubierre drive, can you theoretically ...

Question Flying commercial airliners with ground power?
A thought occurred to me, and I wondered if it could be made practical... This video talks about the possibility of electrical battery powered planes, and in short, while it may be practical to build small aircraft using battery power, unless batteries get an energy storage density about ten times g...

Question Are Air-Breathing Merfolk Viable?
I normally ask sci-fi questions, but oh well... It's fairly well established by this point that gills, while fine for fish, wouldn't work for mammals, as we need more oxygen than can reasonably be found in the water. This goes double for humans, since our brains use a lot of oxygen. Whales, howeve...

Question Do Alcubierre Drives Mandate Time Travel, or Just Allow it?
So, I've heard that while Alcubierre drives might present a semi-plausible way of getting around the light speed limit (if you can get ahold of negative energy), they do so at the expense of creating backwards time travel. Is this an inevitable consequence of using such a drive, or just a possible w...

Question How Close Can We Build Solar Collectors to the Sun?
Say you've got a space-faring civilization that needs a LOT of power. Sure, fusion is a thing, but there's really not that much helium-3 to be found in our solar system, and it's hard to get. So the best way to get gargantuan quantities of energy is to start on a Dyson swarm. We don't need the who...
