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?

@Yeetus Deletus bro animal life survived. Thats more complex life than the first 3 billion years of life on Earth. I mean as in life survived, not only survived but survived in very complex forms. Like apparently there'd still be insects, fish, crustaceans, plants, fungi, anything else deep in water or soil. Very complex organisms. Not just single celled organisms. It is impressive how much life (even complex life) can shrug off without dying out entirely.

Imaging humanity a 10 million years from now (if we survive) is just mind blowing. If we make it that far, we will probably be all over the known universe and be present in millions of planets.

I really hope we can at least get somewhere before the universe eventually dies, it will take so many years of course. Yet, its not as far as we think it is. At least, I hope we leave our mark before we all go into our restfull sleep.

Even if we can invent FTL tech, we will only ever be able to visit a tiny, tiny part of the universe as (covered in another Kurzgesagt video: "TRUE Limits Of Humanity - The Final Border We Will Never Cross") everything outside our local group is expanding away from us faster than or fast as the speed of light.

The best you can do to make the world better is to live your own life as well as you can, contribute to your community where you can, and not blindly follow others when it's the wrong thing to do, even if it's the popular thing to do. You don't have to be a superhero, just do the best you can realistically do. When people try to take on too much or set their goals too high for the world, they often end up doing nothing, nothing that makes a difference, or just complain and get angry or depressed.

Foff Jerkholes
Foff Jerkholes 7 months ago
@Andres Cavada You misunderstand. In every day English speaking, a theory is what you just mentioned. However, that is not what the actual meaning of the word "Theory" is science means. Scientific Theory, must be tested with evidence through experimentation, and is repeatable. This allows you to make predictions with your Theory. If your Theory on a particular aspect of nature you are trying to understand matches the predictions that you now find and observe, and this is also repeatable, you have now a fact about nature. Germ Theory is "just and opinion" in your mind, however, most educated children understand that is germs, bacteria and viruses etc, make a person sick; say with a Cold or the Flu. Germ Theory is highly verified, so it shows you and everyone else that the theory's predictions are true. YOU MUST UNDERSTAND, THEORIES IN SCIENCE ARE USEFUL TO SOCIETY AND INDIVIDUALS BECAUSE THE WHOLE POINT OF SCIENCE IS TO MAKE ACCURATE PREDICTIONS. You sir, definitely want to know what will happen in your life if you make decision A and the turn out will be out come B. Everyone wants this as it increases your ability to be successful in life, mate, have children, earn a living, find food etc. Science is what has made your life possible, because of its "Theories" power to make SHARP PREDICTIONS. It allows engineers to understand loads that steel can handle and what is needed to make certain octanes of gasoline for your car to drive. If you didn't have science, you would not be driving a car, looking at your screen, have plumbing, use electricity; you know, live your entire life. Our ancestors in hunter gather tribes did not have a name for SCIENCE, yet, but they still used basic "Theories", just without realizing it. They knew if they picked up a rock, then let it go, it would fall to the ground, that if they fashioned a lighter rock, with a heavier rock, to make that lighter rock have a razor edge in which to hunt and pierce the flesh of prey to eat meat, it would work. That is scientific theory in action. The "Big Bang" Theory I'm assuming your mentioning, is highly testable, repeatable and has made sharp predictions that all came to be. You are wrong in understanding the Big Bang Theory, has the Theory doesn't try to say what banged, just 10 to the minus 35 seconds after and forward to today, after the bang. Now, what the actual Bang was, there are many hypothesis out there, and a hypothesis is really what you are meaning to say. There are many models for what the bang actually was, we just need an experiment that is repeatable and observable to become a Theory. Those are currently being worked on as we speak. If you wish to add to humanities knowledge of this endeavor, you should go back to school and take as many math courses as possible, work your way to a PHD in Physics, Astrophysics, Particle Physics, Astronomy or Cosmology to name a few degrees. Work on your Post Doc. Decide whether to be a Theorist or Experimentalist, and begin you discovery process. Yes, you Andres Cavada can if you try hard enough, discover the bang! Wouldn't that be great! You would certainly become a Nobel Prize winner, have your name popularized amongst the educated and rightly stay humble and wallow in the sweet bliss that you have unlocked a higher understanding for mankind and all of eternity for that matter.

A supernova is so powerful that even the neutrinos which hardly ever interact with matter, would cook you from such a distance. Look up the xkcd article about it.

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.

Soken50 10 months ago
@unknow11712 Wrong, I want to, but it wouldn't be very reasonable without further evidence :x
Daily kitten cuteness!
The only other possibility that was eliminated was a solar storm, based on the solar maximums, but it’s still possible that the sun did it, just extremely unlikely. Also other solar storms that we know of haven’t caused this effect, which means if a solar storm did do it, it was unbelievably massive.
Sune Rasmussen
Sune Rasmussen 10 months ago
The reason they could figure that out is the particular _kind_ of radioactive iron that was found - iron-60. It's only produced by supernovae, and yet it's never found on Earth in mines and the like, as with its "mere" 2.6 mil years half-life, all of it would have decayed away (to cobalt-60) since the formation of the planet.

@Anonymous maybe, but I think it's unlikely very many exist. Back then, oxygen-consuming life existed. It just couldn't proliferate until algae changed the earth's atmosphere. First we need to find a N2O consuming creature. That's hard too; that N-N molecular bond is strong as hell. Not a lot will convince 2 nitrogen atoms to split. NO2, that's a different story.

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 RU-vid. (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 RU-vid operation. Don't get me wrong, I enjoy RU-vid and consistently watch it, but you also have to remember that some RU-vid 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.

This video was uploaded to the German Kurzgesagt channel yesterday sporting the funk label. Funk is part of the content netzwork of ARD and ZDF, which are two German public television channels. German public broadcasting is funded by the 'Rundfunkbeitrag', which is a tax that's legally not actually a tax but binding all the same. In short, Kurzgesagt videos are partly funded by German public television.

Fascinated by the idea that some supernovas wouldn't harm earth much but would make space travel impossible for thousands of years.

Only based on current technologies (largely relating to radiation shielding). Since light from a supernova travels at 10x the speed of the radiation, we'd likely have many centuries after detecting the supernova to prepare. At 100 light-years, for instance, it'd be another 900 years after detecting the supernova before the radiation actually reached our solar system. That's a *long* time for technology to advance and preparations to be made.

The fact that life still manages to hang on through a super nova 4 lightyears away is incredible.

Great video. It touches on a topic I'm interested in. The current system of economics is barely surviving a global pandemic and international war. It's unlikely it would survive such an event as a supernova. Have you done any videos on a better solution for global economics that helps humanity exist without the disruption?

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.

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!

I bought kurzgesagt "Universe in a nutshell" mobile app, just to support the channel in my little way. Also coz I figured it would be damn *good* Boy it is! The visuals are impeccable, and the descriptions of each entity, are funny and thus memorable. What's most remarkable is how they scaled everything relative to each other from the smallest strings to supermassive blackholes. It does feels like the entire universe is in your pocket "correctly". Or like a book about our universe, but literally the best one out there. They're undercharging as far as I'm concerned for the app. I'll make the same comment in other videos of the channel. Why? To promote their app because I don't see anyone talking about it. It's that good. More so, I want my fellow humans to be educated. Other day I found out that my 34 years old friend didn't know that we're living in milky way and there are other galaxies around us. UNBELIEVABLE. He must've been living under a rock bigger than Sagittarius A (The black hole in milky way galaxy). So yeah, go buy their app.

I don't know why, but there's something peaceful in knowing that it's highly likely that all life is eventually wiped out and has to start over. It's like life is just around to observe a tiny sliver of space-time - to find awe in the universe and self existence.

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 9:17, they subtly added the OST from their video on stellar engine made 2 years ago where they talked about how to move the solar system out of harm's way.

It's reassuring that after listing all of the horrible things that could happen if a supernova were close enough to hurt us, you then point out that no, there are no stars likely to go supernova that are close enough to hurt us.

between one, and four. Space is big. In the core, the number is higher, but it's still under a hundred.
AuroraOurania 10 months ago
@Wolfe Wright And due to how short the lives stars big enough to generate type 2 supernovae are, a large portion of those happen near their sibling solar systems from the same nebula, meaning they're not all that much older, and thus haven't had time for life to develop in the first place.

I watch these videos and scared, especially since our ozone layer has gotten weaker since humans began polluting the atmosphere with toxic chemicals. Or the fact these these random events can happen at any moment and could just wipe out our planet…. or galaxy.
@WinnPro Technically our ozone layer is getting so much "stronger" with the pollution that it traps "heat" enough to become it's own power core. Anyway if that's what you're primarily afraid of then your life must be peaceful because random events like these have so little probability of happening in our lifetime and even less to actually impact us that it's actually the least dangerous thing that can exist for us out there. Of course it's different if we look at it in a civilization of species scale as it will for sure happen one day but that's a problem for my grandson's grandson's grandson's grandson's...

@Myname'sbigMyname'sbigMynameisbigMyname'sbigI'mBIG true. Well at first it was a black hole as something I was worried about. But yeah that problem might not happen for another dozen generations or so.

I was under the impression a nearby supernova would simply blow the atmosphere from earth, leaving something like Mars, with 1mb of surface pressure - practically a vacuum.

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!

María Sofía Luengas Salazar
Its impressive how life can re-start itself all over again, and man, its so interesting how a supernova can afect a planet. In the end, I hope that before the unvierse dies and we all rest, it doesn't happen, so that we can at least make some disoveries and then part from this universe leaving our mark.

My favorite explanation of the power of supernovae while trying to relate it to our poor caveman brains on an intuitive level goes, roughly: "However strong you think they are, they're stronger. No, even stronger."

Hi, if you are not saved, and would like to be included in the rapture of the church. Believe that Jesus's death on the cross, was enough to pay for ALL your sins , yes ALL ,(past, present and future) That is what the Gospel is about. We are saved by GOD'S amazing grace, through our faith in Jesus's sinless life, death on the cross and resurrection 3 days later . No additional works needed. It is literally that simple. Ephesians 2:8-9 Romans 10:9-10 Romans 4:5
