Anyone selling "warp drives" that do not go faster than light kind of missed the point of why people are excited about warp drives.
And if the video @gmartire just posted is explaining the paper correctly, this warp drive also doesn't accelerate anything. You have to figure out how to speed up on your own.
I don't really see why anyone would bother doing any of these things. To dilate time better? I'd rather invest the same amount of mass towards a larger engine/fuel so that I can go faster, dilating time further and getting me there sooner.
- threesongs 5y agoIMO the paper clarifies the misconceptions about all warp drives. They all need propulsion, for example, to be consistent with physics.
- handol 5y agoDoesn't that mean that warp drives are not possible? I mean if the device can't produce a driving force why call it a "drive"?
- krapp 5y ago>I mean if the device can't produce a driving force why call it a "drive"? Because Star Trek called their thing a warp drive and that's become the general term for this kind of speculative technology.
- hinkley 5y ago> I'd rather invest the same amount of mass towards a larger engine/fuel The rocket equation is every bit as unsympathetic to your desires as the laws of thermodynamics are. Fuel requirements go infinite very quickly.
- blamestross 5y agoThe FTL part of the warp drive is the useless part. The real obstacle to space exploration is the rocket equation. Going FTL doesn't help if fuel needs still scale quadratically with distance.
