We've got a theoretical basis for warp drives [1]! Casimir effect-based propelentless propulsion! Nuclear engines in spaaaaace! How much more theoretical basis

We've got a theoretical basis for warp drives [1]! Casimir effect-based propelentless propulsion! Nuclear engines in spaaaaace! How much more theoretical basis does your contrarianism demand?
We've got a theoretical basis for almost any alien technology that comes short of violating the conservation of momentum or breaking the speed of light. Doesn't mean we're any closer to making an SSTO space ship.

- mcpackieh 3y ago> Alcubierre drive Relies on "exotic matter" that violates known laws of physics.
- akiselev 3y agoIt actually doesn't violate the laws of physics. Matter with negative mass has never been observed before, making it purely theoretical. Theoretical basis! Besides, exotic matter is a shortcut to the energy required, not a necessary part of the Alcubierre drive.
- mcpackieh 3y ago> Matter with negative mass has never been observed before, making it purely theoretical. It's worse than merely theoretical because the theories we use to describe reality at present don't give us any reason to believe such exotic matter must exist, and there is no empirical evidence for such matter existing. But slice it anyway you like, the Navy isn't operating these and there is no theoretical basis for explaining the sort of antigravity craft that UFOologists claim these Navy videos show. They aren't Alcubierre drives, that is simply absurd.
