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?

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.
-
I love how varied the content on this channel is. One day it's, "Look at this cool ant," the next it's, "Boy wouldn't it be fun if we went extinct?"
-
Y'all say some of the most concerning things sometimes, yet stay perfectly calm. Props to the voiceover!
-
I absolutely love how concepts from other videos were integrated into the vision of the future. The Dyson ring and solar engine were lovely touches.
-
Honestly, it's bloody impressive that life can shrug off a supernova even as close as that. Life finds a way.
-
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.
-
The amount of times humanity could have not existed because of how the galaxy works genuinely blows my mind.
-
Our position in the universe like we are not close to anything dangerous and the perfect condition for life to exist just blows my mind
-
This channel is one of the best things that has happened to humanity since the emergence of the internet.
-
you guys make me wanna live, and maybe change the world for the better
-
The reveal of the two headed snake while talking about how radiation from cosmic rays would increase cancer and mutation rates to a noticeable level gave me goosebumps. So good.
-
You guys are making science and space and other topics look very interesting to learn and very fun!
-
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
-
What I really love about this channel is that when it discusses topics that could destroy earth, they assure the viewers that what they’ve talked about is extremely unlikely to happen, which probably helps calm down the kids that are scared to death.
-
i love how much quality and effort goes into the editing, sponsorships, etc. Plus Jimmy is such a nice guy it makes everything so much better
-
-
I love the subtle change in music as the video goes on.
Also, I love how you're well aware of the existential dread you can impart on others, but how you can use science to dissuade that dread too. -
I'm surprised by the amount of damage a supernova could do to underwater life. I expected the water to shield all of the radiation, with rising temperatures being the only concern.
-
The fact that even some life would survive a supernova 4 light years away is extremely impressive and shows how resilient life is
