The Most Extreme Explosion in the Universe

Sources & further reading:

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.

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

[jabajoba]

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

[PlanetXMysteries-pjnm]

Science and the universe are something too sublime for me. Thank you for letting ignorant people like me see more of the universe. I really like this channel

[zacharyreed]

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?"

[johnchessant]

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.

“The radiation and mutation rate would not be enough to cause a mass extinction…”

*shows peaceful animals in a jungle landscape*

“…but it will be noticeable.”

*snake casually reveals it has two heads*

[joeburnover]

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

[bmouch]

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.

[warlikemicrobe]

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

[hugo]

I’ve been watching this channel since I was 16 and I’m 21 now yet you guys have never disappointed with the animation. Keep up the good work guys! 👍

[asurmenhandofasuryan]

The thing about these videos is they're entertaining, educational, and sometimes tugs at your emotions. Kurzgesagt really is one of the kind.

[cntoesussie]

Y'all say some of the most concerning things sometimes, yet stay perfectly calm. Props to the voiceover!

[thewingsoffried-om]

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

Stage 1: Thousands of Light-Years Away 1:44
Stage 2: 300 Light-Years Away 2:04
Stage 3: 150 Light-Years Away 3:04
Stage 4: 100 Light-Years Away 4:26
Stage 5: 25 Light-Years Away 7:09
Final Stage: 4 Light-Years Away 7:55

These videos are TV quality, yet you produce these and offer them to us for free -- not on one channel, but on multiple channels, most of which required translations -- all for free. I respect you. You guys are one of the channels that make YouTube. (DISCLAIMER BELOW, because there's a lot of debate in the replies.)


A lot of people have taken "TV quality", to mean bad. However, I want to make it clear that I didn't mean the comment as an insult, but as a compliment. It is also important to note that I did mean streaming services, such as Netflix, not cable. Though I spend virtually no time watching either, this comment meant more so that this is quality content, that I could see becoming official rather than a YouTube operation.

Don't get me wrong, I enjoy YouTube and consistently watch it, but you also have to remember that some YouTube channels (such as this one) are more... polished, than others, especially considering that this is the same platform that has the family vloggers, and "DON'T CALL AT 3 AM!!! 😲😲" videos.

Honest to god Kursgesagt is one of the greatest educating channels out there. With the quick release time of videos and the stellar visuals, it is probably the /best/ of them. Kudos to the Kursgesagt team who give us all the high quality work!

[_monolithic_]

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.

For years I've evangelized this channel to my friends and coworkers as the gold standard of educational content, and I still get giddy when a new video comes out. I've purchased dozens of calendars, posters, and journals, and I will happily continue to support this amazing channel. Cheers, Kurzgesagt!

This would be horrible for the trout population

[thetherrannative]

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.

[flightlesslord]

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