Supernovae are the most powerful explosions in the universe, unleashing enough energy to outshine galaxies. We have no real metaphor for their power – if the sun were to magically go supernova it would feel like you were being hit by the energy of a nuclear explosion, every second. For weeks.
While supernovae are the engines of creation, forging the elements that enable life, they also burn sterile whole regions of galaxies. So what would happen if one hit earth?

  • @veritasium
    Great video on supernovae! Amazing that we were both working on the same topic at the same time. I hope everyone knows that these videos take months of lead time for both of us so there is no way one video was inspired by the other or vice versa.
  • Honestly, it's bloody impressive that life can shrug off a supernova even as close as that. Life finds a way.
  • @avocado9795
    This channel is one of the best things that has happened to humanity since the emergence of the internet.
  • @kjohn5224
    Imaging humanity a 10 million years from now (if we survive) is just mind blowing. If we make it that far, we will probably be all over the known universe and be present in millions of planets.
  • @azureeyepatch
    you guys make me wanna live, and maybe change the world for the better
  • Y'all say some of the most concerning things sometimes, yet stay perfectly calm. Props to the voiceover!
  • One of the best things about this YouTube channel is that it gives science backed information which isn't normally accessible, breaks it down to a level where almost anyone can understand, constantly updates us with new research, and gives it to the public for free. Thank you for what you do, Kurzgesagt
  • Hello, I love the videos you do on space, it would be great if one of your next videos talked about the aquaponics system and its use in space missions. 😄
  • Another amazing video! This channel really has some quality content on it. I always come back to watch whatever the new video is :)
  • Its impressive how life can re-start itself all over again, and man, its so interesting how a supernova can afect a planet. In the end, I hope that before the unvierse dies and we all rest, it doesn't happen, so that we can at least make some disoveries and then part from this universe leaving our mark.
  • 9:14 love the stellar engine reference! great video as always, been watching since 2020! Only thing that kept me thinking during the lockdown!
  • @jabajoba
    The amount of times humanity could have not existed because of how the galaxy works genuinely blows my mind.
  • @drivernephi7494
    The fear of a supernova exploding within my lifetime is so small I’m not worried at all I’ll probably be dead if a supernova ever happens within my lifetime
  • @zennir48
    The amount of times we could just not exist because of the "Laws of the Universe" is too crazy to be true..
  • @ernesik4636
    I love the tonal whiplash of hearing how disastrous things could be at the same time as I'm vibing to the music, feels like vibing to abandon ship from subnautica
  • Can you also make a video about how would a supernova effect the nearby stars, gas giants and barren planets.
  • You should do a video explaining how sleep works and the different cycles and types of sleep, might be cool
  • @joeburnover4110
    The fact that even some life would survive a supernova 4 light years away is extremely impressive and shows how resilient life is
