The problem is that we don't have the foresight necessary to know this. If we crack FTL or inertial propulsion, a whole ton of options open up.

- nabla9 7y ago> If we crack FTL .. we can time travel. But we don't see anyone from the future here, so it seems to be impossible.
- baq 7y agono need for FTL travel if we can just bend the universe hard enough.
- antepodius 7y agoIf you bend the universe, you're bending time, as well.
- rpmisms 7y agoNot if the Alcubierre drive works, which there's no reason to believe it doesn't. Cracking FTL doesn't mean just stepping on the gas really hard.
- nabla9 7y agoThere is a good reason to believe that Alcubierre drive does not exist. It's allowed by Eninsteins equations if you have negative energy but quantum gravity would invalidate it. Einstein's equations allow all kinds of weird solutions that physicists don't believe can really exist. Discovering them is just a way to study the equations theoretically. Alcubierre Warp Drive Metric or Gödel metric (rotating universe) are just two of them.
- AnIdiotOnTheNet 7y agoFTL travel is straight up science fiction, ok? Look, I would absolutely love to be proven wrong on this, but literally everything we know about physics is telling us that FTL is impossible. Ditto inertia-less propulsion to a slightly lesser extent.
