    In my opinion, this is a worthwhile read for fans of
    science fiction.

    13 faster-than-light travel methods from sci-fi that leave Einstein's
    theory of relativity in their space dust

    By Richard Edwards published 2 days ago
    Cosmic speed limits can be a major inconvenience but they've rarely
    stopped science fiction in its tracks.

    When it comes to space travel, Albert Einstein's theory of relativity is
    a major inconvenience. With the laws of physics (currently) prohibiting faster-than-light travel, velocities are limited to a mere 300,000,000
    ms-1. By any Earthbound measure that's very quick indeed, but it'll
    still take you 4.2 years to reach our sun's nearest neighbor, Proxima
    Centauri.

    That sort of timeframe clearly isn't conducive to all-action space opera
    — imagine if the Millennium Falcon had taken a decade to travel from
    Tatooine to Alderaan in "Star Wars: A New Hope" — so sci-fi writers have
    come up with numerous ingenious ways to jet around the cosmos at quite ludicrous speeds.

    We say this with a few caveats… Hollywood tends to assume that
    spacecraft have access to limitless sources of energy. And that —

    Actually, nothing can be *accelerated* beyond the speed of light. That much is certain.

    What remains uncertain is traveling faster than light by starting out going faster than light.

    Of course, this is completely hypothetical at this point. But also completely unknown. Einstein's equations say nothing on this.

    It's a serviceable taxonomy. At first blush, the following non-fictional alternative to Neinstein's time-eaten cosmic speed limit seems to fall
    into category 9:
