Keep up the great job!

We're familiar with Zeitgeist thanks Endless notifications.. dear God what have I done

Ohhhhhhhhhhhhhhh, I thought the information in this video was from a previous Kurgz video, but now I remember, the video was yours. Thank you!!

eh, what a timing. well complemented 👍

Tu eres el maestro longaniza

Yu also make a vedio on this topic

And then a deep talk about depression.

@Lennox Parsec and then the fact you have a high chance of getting a auto immune disease in your life time

And who could forget about that giant star that probably never existed?

and also “lol imagine if you turned very small”

ahahahha indeed!

*they didnt shrug it off

@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.

Of course the beginning of the universe is a theory, and not a scientific fact, that was failed to be mentioned here.

@Andres Cavada how's that relevant at all to what I said, if ur referring to wether the big bang happened or not, maths doesn't lie.

@Andres Cavada almost everything is a "theory" there are no "scientific facts"

Your pfp scares me

@Jack good :)

You know you stand zero chance of being affected by a supernova - right? That was the whole point of this video. If it scares you, then you can't calculate/perceive risk correctly.

Should we call your profile picture Grerby or Kirg?

@Skylar Sky, Queen of Chadutuva Either or is fine

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. As mentioned in the above video, 94% of the known universe is already gone beyond the veil

@Oshroth Didn't that video contain an inaccuracy?

@Anonymous that was the original video

And how many times Humanity should of end shows how capable we are as well how we are fragile and could end quickly The universe is a great and cruel world

@F Ismail I don't know how it shows how capable we are

@Curiosity the ice age and the last human episode and super volcano I was talking about

@F Ismail ''cruel'' is a human made conception. The universe is just the universe.

For a second I thought you were talking about a supernova headed to earth xD

@RedBirb I've just done that same thing :')

That's probably the entire reason why we're here at all to talk about it

Cause we are just living in the "period" between two mass extinctions.

@Edd Exactly right. Funny how humans tend to apply reverse logic to suit their needs. While, in fact, we have been just plain lucky up till now.

It's called the Anthropic principle: If we weren't in this sweet spot, we wouldn't be around to talk about it.

We got a lucky spawn

no ikr?? like i dont usually feel this way and interestingly enough, they do it while telling us very alarming things

Best of luck. Is hard

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.

search "How Kurzgesagt Cooks Propaganda For Billionaires"

@erik david hauser man what

Of course the beginning of the universe is a theory, and not a scientific fact, that was failed to be mentioned here.

@Andres CavadaWhat does that have to do with the topic?

@Andres Cavada what made you feel the need to bring that up

@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.

I'm glad someone pointed this out. This channel is overall very responsible about making sure that they don't cause unnecessary panic.

It's probably going to be cockroaches.

well if earth turn into venus life will not survive long

@GeneGear Tardigrades: chilling False vacuum: *h e l l o t h e r e* Tardigrades: still there False vacuum: _wait what in the f_

@Killkor there is a difference between hitting "delete" and the "power" button

Of course the beginning of the universe is a theory, and not a scientific fact, that was failed to be mentioned here.

​@Andres Cavada that isn't even relevant to the video

E‎‎

SciShow has been doing this for years too though.

"One of the best things about this ESvid channel is that it gives science backed information" - quoted from you. I would argue that is the most dangerous part of this channel. One mistake and it could become law, by accident, with no possible way of going back.

@Daniel Duncan That's why they have a lot of different sources and they work with scientists and experts

Ikr, I can name atleast 20 channels that give you good scientific information!

dude supernova's is just doomguy on a galactic scale

​@Yeetus Deletus more like Duke Nukem because it nukes it's region of the galaxy

This needs to be pinned!

@thehochmaster2 Will animals that can use nitrous oxide evolve? A mass extinction event was caused by oxygen in the atmosphere, and now, we need oxygen!

@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.

@thehochmaster2 Why would it need to break it apart? I don't think we break up O2 into two oxygen atoms as humans can't actually use oxygen of that form (where they're individual atoms, not bound up)

Of course the beginning of the universe is a theory, and not a scientific fact, that was failed to be mentioned here.

well... there are alternatives ... but you don't want to think that a civilization advanced to the nuclear age and then killed itself. or a space civilization bombed this world for some unknow reason .

@unknow11712 Wrong, I want to, but it wouldn't be very reasonable without further evidence :x

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.

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.

RUN FOR YOUR LIFE

@yachet_mp why ?

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.

@Steamrick damn that's cool i didn't know that. its good to know that the german government is actually doing useful with tax money instead of wasting it in useless ways lol

@Anustubh Mishra It's not actually tax money, it's citizens' money taken in by a private organization for public use. Despite that, it's not optional and people have gone to prison for refusing to pay. It's... a rather controversial topic. That said, Kurzgesagt is one of the best uses the money could be seeing.

Interesant placut

@Vasile Marian Giarap Is that Romanian?

Thumbs up

Eres maestro longaniza del profesor Jirafales

Wow

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.

Watch the one about...

I’m a bit unhappy that we will have to move out of the way just because a star goes supernova. We need to build a Dyson Sphere.

@MarcosElMalo2 and to do that, we'll probably need space tethers!

@Luke DS That’s not the point. The point is that supernovae can’t tell me what to do.

E‎

Now that I think of it, I'm also watching since I was 16 and I'm 21 now.

Same but since i was 14 now im 22 💪😎👍

I am currently 16 and hopefully I will still be watching when I’m 21

Wow you make me feel young

Imagine watching this on PBS Kids back then instant classic, if not already.

who asked?

@Dino Gt I asked

Capital G on the God

I would be SOOOoooo happy if a supernova blew us up

@Joseph Carrino man im de-

@Joseph Carrino dude i got a burn right after reading this

I discovered this channel when my teacher gave a video from this channel for an assignment in 2020 and I've been watching Kurzgesagt ever since.

They're almost at 20 million subs. Great Job K-Team!!

"Taxes here I come"

Very bright but, ohio has been through worst

ok

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

@Jona7Fer jesus sounds like some bloke

@Sam brads That “bloke” sacrificed His life to save yours. Do you not see the battle between Good & Evil going on before your very eyes?

Exactly

I love that it is consistent, it became Kurzgesagt's signature

The magnetosphere from the supernova was sick fam!

Not some. ALL the art.

True, I really love all Kurzgesagt videos

between one, and four. Space is big. In the core, the number is higher, but it's still under a hundred.

@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.

@WinnSC 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.

It’s Bionic!

Doni is gonna make a supernova on the server

Bro thinks he’s Kevin

hi bionic chan

I bet you're gonna make a "Minecraft but it's supernova" Modded letsplay at some point too considering the large volume of content you put out.

You saw a satellite flare.

@Baz Pearce this was extremely bright, but you could be correct. I just doubt it

@Jack Oakley Believe. Super Novas last for weeks and months, not seconds. Apart from 1987A there hasn't been one for over 400 years visible to the naked eye. It sounds like an Iridium flare. They were the original GPS satellites and they had huge solar panels that made them flare up brighter than Venus on occaision. I saw hundreds of them during the 2010s. The brightest i ever saw was about minus 8 magnitude, almost as bright as a full Moon.

I mean if you think about it life has had all this time to evolve without being entirely wiped out, what are the chances for that to happen right now in our short lives?

​@Omniversal Insect Some things we are uniquely vulnerable to, but the rest of life isn't. The most obvious example is a human centric disease, however for a more cosmic example consider a powerful coronal mass ejection that is aimed at us. Our modern electronic society would be very negatively affected by that, while the rest of life would just see a pretty light show further south than they usually appear. And in fact we've seen such a thing quite recently - look up the Carrington event.

I would be SOOOoooo happy if a supernova blew us up

dont worry supernova is instant, it is like if you eat nuke, it is instant 😊

In 2018, while looking through my telescope I saw this star that suddenly flashed and then went out. I think it was a supernova.

I totally agree with you. I am so happy to watch them

go away

@Deutsch mit Purple proud to be deutsch?

@Thor Odinson Stolz darauf, dass Englisch die beste Sprache ist? Eifersüchtig viel?

Lol
