I know we’re primarily an automotive site, but we’re really a site for all manner of vehicles. We cover airplanes, trains, motorcycles, and I’m not opposed to covering the occasional elevator or moving sidewalk, if, say, the Otis people want to drop off a press elevator at my house. We also cover spacecraft as well, […]

    This is 632 megameters (million meters) per hour. The speed of light is 1.080,000 megameters per hour. So this object is traveling 0.58% of light speed.

    edit:

    0.058% of light speed. thanx modva

        The other thing that’s sort of impressive is it gives us an idea of the sheer scale of the speed of light. The fastest macro object we’ve ever created (I’m sure there’s tiny things we’ve made and then gotten going really fast with a particle accelerator) can only go 0.058% of the speed of light. There’s this speed limit of the universe at c, but it’s so fast we can’t even hit 0.1% of that speed limit.

          It’s wild to think that light is fast enough to circle the equator 7.5 times per second.

    For the non-clickers of the link (like myself):
    It’s gonna be the Parker Solar Probe, skimming the sun’s atmosphere in ever tighter and faster elipses with each orbit, gaining more and more speed with each pass.
