[Alneyan]

Ah, but the Hitchhiker's Guide to the Galaxy provides with the perfect answer to this problem. Let's see: there is nothing faster than light, save for bad news, whose speed is subject to completely different laws (*). Such are the words of wisdom contained in the Guide.

Therefore, a vessel powered by bad news would be able to travel at a unpareled speed. Alas, this cannot be tested in practice because of the effect of such an energy source on the crew; depression occurs too early, as nobody can watch such a flow of bad news without losing all faith in the universe.

(*Feel free to provide the actual quote from the Guide about the speed of bad news)
