    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?

    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

    Hello, I love the videos you do on space, it would be great if one of your next videos talked about the aquaponics system and its use in space missions. 😄

    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

    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.

    This is a remarkable video. Could you please tell me how you did the animation?

    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 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)

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

    One of the best things about this CZcams 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 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.

    Never have I learned something from the first word in a video until now!!! Thank you for the plural form of supernova!

    Can you please make a video about sleep disorders? Insomnia, sleep apnea, upper airway resistance syndrome, restless leg syndrome, narkolepsy, plain snoring?

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