furiously taking notes on comedy throughout this thread. Beginning to suspect that subject uses my disdain of his RAMA theory to bait me into science... It's not completely impossible, that we know of, yet? But if you were using one, you wouldn't want it to radiate waves, as that'd be a loss of energy from your generator. It's likely that it'd still be somewhat lossy, especially during the process of turning it on or off. If you were to actually achieve faster-than-light travel, that should create a sort of space-time shock wave, which, just like in the atmosphere, would take the form of a conic. That should be the loudest signature. And oof, the limits of detection on an Alcubierre warp drive? If cosmology is the wild west of physics, this is like /b/ in 2006, since we basically have no idea how Alcubierre could work. The only thing I can say fo sho is that it had better be close, maybe only a few galaxies away? I've no idea.Alcubierre warp drive
