Still, even if you were right I don’t think you need convincing that many here are optimistic about warp-drives eventually becoming an actual thing.

If so, then we’ll have to choose another letter for “c”. I’d vote for “b”, meaning “bulb” in honour of that sly huckster Edison.

The whole “it might have happened already” argument that everyone says about these things might not turn out right.

I mean, if the warping of spacetime for the purpose of FTL travel isn’t possible under any condition, then we can say causality itself propagates at the speed-of-light.

Which means Betelgeuse will explode when we see it explode, not “600 years ago already”.

I don’t see how we’re going to avoid developing nuclear engines.

Chemical engines are the only game in town for hoisting stuff into orbit, but once you’re there, using the same stuff for human rated interplanetary travel just seems completely wasteful.

I see us building nuclear infra with chem rockets, then finally shipping up the actual engines.
