    Okay, here's an old answer: NO.

    You may need some breif background: Einstein says nothing with rest mass can travel to a speed of ≥c. There are tachyons, with an imaginary rest mass, and travel natually faster than light, and particles with no rest mass travel at exactly the speed of light. Tachyons have not been observed, only thought of. Luxons are what we know and love, they travel at less than the speed of light

    ooops, I'm really sorry, I mixed some things up. Photons are luxons and tardyons are particles that travel slower than light, tachyons travel faster, In short

    Luxons have zero proper/rest mass, tardyons have positive, and tachyons have an imaginary number as proper/rest mass

    its impossible to travel at the speed of c because of something about requiring infinite energy.(i remember from the science channal) But we could use wormholes, if we learn how

    This is a four-and-a-half year old thread.

    Furthermore, wormholes may not exist. There is certainly no evidence for them.
