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.

The amount of times humanity could have not existed because of how the galaxy works genuinely blows my mind.

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!

One of the best things about this KZfaq 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

The fact that even some life would survive a supernova 4 light years away is extremely impressive and shows how resilient life is

The poor birds in these videos. They either get blown up, melted, disintegrated, stabbed, frozen...

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.

What's really fascinating is the fact that we found a layer of increased levels of radioactive iron in the archaeological record and we were able to eliminate any other possibility besides a supernova from 300 light years away.

I'm in love with the fact that they've been ending their recent videos on a relatively happy note to combat the existential dread they usually inspire.

I like the visuals depicting the different stages, so I’m timestamping them.

Honestly, it's bloody impressive that life can shrug off a supernova even as close as that. Life finds a way.

I first discovered Kurzgesagt back in 2015 with their videos on nuclear energy. I remember thinking at the time, "Wow, this channel makes some great content. I hope they end up growing and getting more attention." Seven years later, my wish has most certainly been fulfilled.
