Yeah. I draw the line at magnetic monopoles, which are hypothetical (and it's not looking good for GUTs at the moment), but they are infinitely less bullshit than tachyons and such.
Wormholes and reactionless propulsion are too much for me. It's a cute idea, but I don't believe wormholes exist outside homework problems for students of GR.
- _hypx 4y agoMagnetic monopoles are indeed speculative, but at least the theoretical foundations are pretty sound. Dirac predicted them after all, and they play nice with quantum mechanics. Wormholes and the like are where you get really wild problems like time-travel, which you have to arbitrarily prevent via more speculative physics.
