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.

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

Does anyone else feel this is a new era of videos? Some feeling in me feels these are way more knowledge filled, either that or ive been binging old vids lately lol

Just throwing this out there but I'd love to see a series on Quantum computing and especially Time Crystals. Very intriguing

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.

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.

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

The best part about Kurzgesagt, apart of course from the beautiful scientific videos, is that they always include music from their previous videos to cite references. For example, at

Sounds like a great idea for a game. Instead of nukes in Fallout, it could be a supernova in "Nova".

Can you do a video on whether time travel into the future or past is possible. I’ve heard a lot of debate about it, and it got me thinking.

If we do end up in an end of the world scenario can you please narrate our next actions, your voice would be incredibly helpful

One of the best things about this ESvid 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

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.

Could you please do a video about what would happen if Venus & Mars swapped atmospheres or locations (assuming the change in gravitational forces in the solar system doesn't completely screw up Earth)? Would it make the planets less or more hospitable for human colonisation / terraforming? Would Mars become hot enough for their frozen lakes to melt, yet cool enough to keep them from evaporating? What would be the consequences of swapping positions vs simply swapping atmospheres? Would the surface of Venus become a place we could travel to? This is something I am very curious about.

Could you offer some clarification on the range of "Radiation" you reference? I am assuming from the symbolism that you mean the part of the spectrum that we associate with isotope like uranium and plutonium. It would be interesting to know what sort of effects that may present such as, I've heard, that radioactive isotopes can feel very warm and certain concentrations without reaching boiling temperatures. (also that this means it's likely doing a lot of damage to cells)

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

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