  • @paubuigues4363
    Thank you Kurzgesagt, I was planning to wage an interstellar war soon, this will surely be helpful
  • I love how instead of deciding to help humanity build the weapon, kurzgesagt instead decided to help the aliens
  • @EeveeMaster547
    Absolutely loving how with the Electron Beam you can hear the narrator carefully counting each '9'
  • @slicersugar
    “The bigger it is, the longer its range.” Didn’t think I would be able to take a kurzgesagt audio bit out of context.
  • @genius31415
    Imagine waiting 84 years just to hear that your intergalactic weapon hit a random planet that was in the way.
  • @CryptoNWO
    If you sent a pebble fast enough you’d be able to destroy an entire planet
  • @Sabz1679
    Love how you's went full "3 Body Problem" in this video 👌🏽
  • So fascinating to learn that humanity is completely defenseless to advanced hostile aliens in at least three different ways!
  • @flibber123
    If the aliens sent a message like "Surrender within 24 hours or face destruction" we could send a message back "Is that 24 hours in your time or our time?". Considering the distance involved, we could gain millions of years of extra time just by trying to sort that out.
  • @winterwings2473
    Kurzgesagt: "Better stay relatively quiet" Meanwhile NASA: send naked human picture into space
  • @bokayo4256
    I love how there is a random ash ketchum in a Kurzgesagt vid
  • Fun Fact: if there are aliens watching us from around 78 light years away, they're watching WW2, if it's 65 million light years away, they're watching dinosaurs.
  • @JasoTheRed48F2
    An interesting follow up video would be how a more advanced humanity might defend against such existential weapons.
  • Once again the music is amazing, and the recalls to older themes are super satisfying
  • @user-td2ny5ln1u
    what if aliens have already launched a "hypothetical star laser" to us and its on its way, very slowly
  • @jujuoof174
    Love these ideas, they are fascinating! The animation is beautiful, super-high quality and I love all the little references as always! Even the “mean” aliens are adorable!
