3 Minutes, 2 Seconds: A Real-Time Visualization Of Light Traveling From Earth To Mars

January 24, 2019

This is a real-time visualization of light traveling from Earth to Mars, and back again. Each direction takes 3 minutes and 2 seconds at a close approach distance of 54.6 million kilometers (~33.9 million miles), for a total speed-of-light roundtrip of 6 minutes and 4 seconds. That means if I mooned the aliens on Mars right this second, the light reflecting off my near-perfect ass cheeks wouldn't reach them for 3 minutes and 2 seconds, at which time, universe willing, they'd be so outraged they'd mash the big red button on their speed-of-light superlaser, and another 3 minutes and 2 seconds later Earth's pesky human problem would be solved. "Pull your pants back up already." Shhhhhhh -- just in case they weren't watching right away.

Keep going for this video, as well as BONUS videos of the speed of light traveling around earth, and to the moon and back.

Thanks to Adam W, who informed me he loves space as much as I do, which is a lie because I am space lover numero uno and have the official paperwork for all the stars I adopted as a kid to prove it.

    Now, I'm not some big shot astrophysicist *snaps suspenders* but I'm pretty sure the distance between Earth and Mars and way longer than what that tiny video shows.

    what in the fake news is going on here


  • Bling Nye

    As far as I can tell, what you're labeling "fake news" is literally your own misunderstanding... This video is Earth to Mars... In the video that depicts light going from the Earth to the Moon, it's stated it's 1.255 seconds, which rounds up to 1.3 seconds.

    lol fuck me youre right

    good lookin out

  • Munihausen

    Hey, 3 minutes and 2 second is PLENTY of time - just ask Eric Ord.

  • Bling Nye

    But what do you do with the extra 2 minutes?

  • Munihausen

    Sob quietly.

  • Wooder

    OK just found out humans can never go at speed of light...so sad.
    So I'll just continue to watch this video and dream.

    Even if we could go the speed of light we start mucking with time. It's all relative I hear.

  • Bling Nye

    We won't need to go the speed of light once we unlock quantum/wormhole/tesseract travel. Even if we could, speed of light travel isn't feasible anyway given the size of the galaxy; you're still talking about 100,000 light years from one end of the Milky Way to the other.

    I'll have Oprah get right on that.

    Seems like light should go faster. Also, if light is that slow, forget space aliens visiting us. It takes way too long and the rent is way too high.

  • Ivanna Pewpalott

    it does, idk what gw is smoking

  • The_Wretched

    3-13 minutes is real for time for light to do the Earth / Mars trip depending on where they are in the solar system at any given time.

  • Nicholas Conrad

    Yeah, I'm pretty sure that's what 5G is going to fix.
