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 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.

20 millions, it's gradually coming. You've deserved this guys, I've fallen in love with everything you propose and prepare. Thank you for bringing such an extraterrestrial content, love u

the fact that a few hundred light years away is enough to make the night glow is a real show of their power

One of the best things about this BRvid 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 amount of times humanity could have not existed because of how the galaxy works genuinely blows my mind.

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

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 was wondering if you might consider doing a video on how different kinds of stars go through their life cycles. I know you talked about it a little in your star size comparison video, but it's really fascinating to me and I would love to see you talk about it in a bit more detail.

No matter what happens, how old I get, what happens in my life, who comes in and out of it, these videos will always be here for me, and for all of us. Techno was a light that shone brighter than any other out there, and he was a real beacon of hope for many of us. I'm just very glad that he's resting now, and doesn't have to suffer anymore. Props to you, Techno, and as the saying goes, "Technoblade nevah dies!"

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 BRvid. (DISCLAIMER BELOW, because there's a lot of debate in the replies.)
