No Warp drive? Say it ain't so!

I'm not sure whether this guarantees no warp drives, but the article is interesting.

To me this is one of the biggest problems of a postulated warp drive (or even just travel at a significant percentage of the speed of light).

"the laws of physics not only prevent us from achieving or surpassing that speed, but they damn us to the severe experience of time dilation. Even if we were to get in a spaceship and travel at near-light speeds, everyone back at home would age spectacularly while we undertook our interstellar journey."

This was a problem with the so-called Bussard ramjet, a design that would scoop up free flowing hydrogen atoms via a magnetic field and funnel them to the ram drive. Supposedly with this design speeds of up to 40% of c could be achieved.

Somehow warping space would need to be figured out. I surmise that studying black holes and their ripples in spacetime might offer some clues, but our physics is far too immature at this point to come up with something promising.

Thanks for the article!
