I think it's always been taken somewhat seriously from the start of general relativity (it didn't take long before the first formal description of a wormhole).

I think it's always been taken somewhat seriously from the start of general relativity (it didn't take long before the first formal description of a wormhole). The discovery of gravitational waves has again provided strong proof in favour of general relativity, but I don't think this is what is preventing people from seriously considering warp drives.
Until a way is found to remove the need for exotic matter or to generate exotic matter it remains a purely theoretical exercise.
- qubex 7y agoThe problem isn’t really the need for exotic matter in enormous quantities (apparently we have a negatively curved universe where dark energy serves exactly that purpose), but rather the aspect of causal disconnection: everything inside the bubble is disconnected from everything outside it, so it’s difficult to envision how the spacecraft inside could be generating, steering, or even shutting down the warp bubble outside itself.
