I’ve previously seen some scientists suggesting that Einstein was wrong about the speed of light in a vacuum being a universal limit. This seems to prove it, at least for particles without mass.

As noted in the article, science fiction often relies on as-yet imaginary — though often scientifically plausible — technologies that side-step that limit, and we’re going to need at least one if we’re going to visit other potentially-habitable planets without delays measured in lifetimes.

(Thanks for the heads-up, GWarner.)
