How Do Stars Die? | Neil deGrasse Tyson Explains...

[@kt420ish]

I love how Chucks face lights up when he grasps the concept Niel is laying down.

[@donaldsmith8648]

Best channel on KZbin in my opinion

[@Periodic-Milk]

You have a good opinion

[@Frog_Man_]

Your opinion is correct

[@Sammasambuddha]

The Force is strong with us! Lol.

[@ermabowman7052]

A bastion of logic and reason in a sea of misinformation and chaos.

[@NanocDark99]

There are some epic Red Dead Redemption 2 channals arround but yeah, this is just as good!

[@peterkallend5012]

Chuck is amazingly poetic in his way of describing his understanding of what Neil has just explained. These two are amazing communicators.

[@yolotheferret]

Their relationship is what keeps pulling me back. These guys are awesome

[@CosmicErrata]

Ditto.

[@t.g.2777]

They are like overachieving older brother and younger brother who became a comedian

[@jimr9499]

Absolutely. Sometimes, even when Neil slowly and concisely explains a concept, dumbing it down for the likes of folks like me, I still don't fully grasp whatever he's talking about. But, in those situations, Chuck will reiterate what Neil just said and then I totally get it. Plus, on top of that, he just makes the whole episode fun/funny! Oftentimes I rewatch old episodes, but if Chuck isn't the co-host it's an instant skip for me!!

[@alejandromedina7826]

They make the perfect teaching couple… is like the good cop/bad cop routine

[@Ungrievable]

“We are not just poetically Stardust, we are literally Stardust.” - Neil deGrasse Tyson This is easily one of the best videos in KZbin’s history ❤️🙏

[@kbataineh23]

My thoughts exactly. How havent we all seen this video. Like how is this not on repeat to every human alive?

[@Mako045]

Pure scientific, witty poetry by Neil and Chuck. Bravo!!!

[@JT_771]

Stellar example of why StarTalk is SUCH a good program. Fantastic content. Very well presented. Can't help but love the enthusiasm of both Neil and Chuck. Hard to think of someone who wouldn't benefit from watching these with an open mind. Viewership should be SO much higher.

[@victorrutledge257]

Indeed, a "Stellar Example".

[@LtNduati]

This is one of those things you can learn and understand, and still be just as amazed that it's true like you had never heard it before.

[@CUBOSH]

the trick is to try getting yourself to feel that way about everything

[@VirajBaraskar]

"Not only are we alive in the universe, but the universe is alive within us." I felt like hugging the universe and thanking it for the wonderful gift of life we have. Wow!!! Just made my day...

When I’m outside in nature and look up in the night sky, I think, this is my church. This is where I worship and the Universe is my God. 🙏 ❤️

[@SweDennis]

This channel never ceases to amaze me. Although I've known of the physics of iron and fusion for a long time, Listening to Neil and Chuck still brings some new feelings and emotions to the table that I didn't have before. Just wonderful.

[@kvtechvarshney5179]

So in this physics of Fe & fusion I wanna ask, Fe is created when all of the lower atomic numbered elemental atoms are converted to Fe. Right? All of the composing atoms convert to Fe or not, & some lower atomic numbered elemental atoms remain? Like N, C, Na, O etc. remain? If not then how come during supernova burst and planet as dust of star contain these lower atomic numbered elements, shouldn't it contain only Fe??

[@miguelcarrera617]

One of the best explainers I’ve seen. I truly enjoyed every second of this. Thank you.

[@Masmikh]

I cried in awe when Dr Tyson reached the Supernova part climax. What a beautiful journey for the start.

[@chrisconaway799]

Neil, please start putting chuck on the thumbnail of videos he will be in with you. Plus I think he deserves to be in the thumbnails by now lol

[@Ashystar067]

Iron pulls off its mask and says "ha-ha! It's me, absorpt-ion" That did it for me😂 I love Mr Chuck & Mr Neil so much. They make me feel like I'm learning along instead of being lectured 👍👍

[@ThishVc-yp9xg]

Absorb-Sion

[@masterofnone3981]

Sure hope Chuck and Neil never break up. No one could do it better than this duo. Neil teaching & Chuck learning with humor is what’s able to hold to the attention span of their like minded audience. ✌️❤️.

[@junobuggy12]

The chemistry with this duo is what keeps bringing me back. I love their explanations

[@Sileonex123]

Often times I fully understand the topics of these wonderful videos... But today I actually learned something new... Thank you

[@MrVvrfly]

Love every single minute of this conversation. What a simple explanation and perhaps the best way to understand US in spiritual terms. Thank you Neil. Chuck you must know it is difficult to keep things together without your wits. I am so glad you both are together.

[@MrZeek1519]

Supernovas and the creation of elements was one of the first discussions that inspired my love of space way back when. Thank you for rekindling that love StarTalk!!!

Iron is the cosmological circuit breaker for fission and fusion. Fascinating.

[@Nolimitslum]

Just bought two of your books dr.Neil and they were signed gotta say I loved the natural history museum

[@jimr9499]

Ah! I'm jealous! I'm only a couple hours train ride away from the city but I haven't been in years. It's one of my (realistic, not that hard to achieve) goals to get to the museum one of these days soon. Definitely going ASAP.

[@AnalogX64]

Thanks Neil and Chuck for another great episode :)

[@Periodic-Milk]

I wish this came out a week earlier I just had a chemistry test on half of what they talked about.

[@oliverdearmas5958]

Yesterday I went to your show, “an astrophysicist at the movies 2” and I loved it. Very funny and was an excellent merge of pop culture and science, so thank you.

[@frankelkjr8041]

Although I’m familiar W/ the fusion process, Neil made it so much compelling as if I’m hearing it for the first time :)

[@kamuroshow4884]

The chemistry between those gentlemen is so good! 😂 a good laugh and informative at the same time. Keep it up!

[@josephkarianjahi1467]

It depresses me a big deal to know that the world shall be without Neil degrass Tyson one day! He narrates complex scientific stuff creating epic suspense with so much ease! Damn!

[@S_C_]

You say this was discovered by 4 scientists but ancient forms of African spirituality already indicate the fact we are Children of the Light ☀️

[@kmmadhu1280]

I loved this

[@cybore213]

The quick answer is that a supernova explosion is so energetic that the shockwave can induce fusion reactions in the star's outer shell, producing the heavier elements. But I would also like to see Niel explain this in another episode as well to get more details.

[@michaelritchie5303]

@@cybore213 There is also evidence that heavy elements are formed during collisions of neutron stars. I watched this a while ago. kzbin.info/www/bejne/kGfUiJuFqberqrc

[@bkbekka3039]

Dr. NdT is the one person I'd love to have a conversation with. Although he is ABLE to have my head spinning & then burst, he is the best at explaining complex theories and facts to someone like me. By "me" I mean a person that craves to understand a knowledge I've questioned, practically, my entire life.

[@jackylukewarm3257]

Your head spins and then bursts. Sounds like big stars rotating and then burst into supernova

[@josefdendunnen]

Thank you kindly for yet another wonderful episode. I always come away feeling more enlightened each & every time. 🙂

[@Ag3nt47-u1z]

Please make a video to answer and explain Chuck's question at the end. I am also curious and would like to know what kickstarts stellar fusion to create stars.

[@ramcymendoza2381]

Another thing that makes Neil an incredible educator is how he uses his hands to explain things. I don't think I have seen someone as fluent as Neil in using their hands to explain the unexplainable.

[@igi-chan]

If you pause at 12:30 and a few miliseconds, : it looks like Neil is force choking Chuck 😂

[@Tony-rh2lp]

Now that we talk about super nova from dying stars, please talk about how the larger stars dying to form blackholes.

Just watched him on PBD. Not his best showing IMO.

[@ranonampangom2185]

@@matthewshull591 He needs to stop going on public broadcasts that are unrelated to space. He's scaring off some misguided, misinformed people from his channel, and while what he says isn't necessarily incorrect, his delivery of information that some people think is "controversial" really needs some work. He shoukd focus on presenting good information, not on trying to forcibly convince the ignorant population.

[@gabrielh.4583]

Nice video and explanation ✌️👍. One question: If star’s only fuse until they make iron and then explode into super novas, How are heavier elements created in space? Thanks

[@nathanaelfontenele2388]

If I remember correctly, at the beginning of a supernova the outer layers implode vary rapidly increasing the pressure even more and fusing iron atoms and other heavier elements afterwards, but by that point the star is in the process of exploding, so there isn't a lot of time for that process to happen, and that's why these elements are so rare.

[@gnarmaw7039]

It happens when stars collide

[@skylark8828]

@@nathanaelfontenele2388 I remember seeing that collisions of stellar objects with neutron stars and magnetars produce the heavier elements in greater abundance.

[@michaeljorfi2394]

@@gnarmaw7039 it's from the energy of the supernova explosion

[@TheJunmengo]

Most people that watch the channel probably have a fairly superficial knowledge of the life cycle of a Star, i heard some of these concepts a lot of times, but Neil always bring something new that i didn't know, like i never knew the Iron death stat was because of energy absortion, and that is because is exactly in the middle of the periodic table, it blown my mind

[@Ken-ki]

Love all your videos, but specially those on astrophysics, and this one is very special, thank you!

I liked this. Can you do another explainer video talking about the lifespan of smaller Stars, like our own sun?

[@jacoblahr]

I wish i had Neil as some kind of teacher in high school. These kids nowadays are so lucky they can just watch this on youtube like i am doing now but im 39 years old. Im past the young bushy tail and bright eyed kid on my way to class 😣

[@BSm2919]

I've heard a little about some of the first stars that could be substantially larger than current stars and that would undergo "para instability supernova". Can you please do an explainer on that!

[@michaelalmstrom1240]

Are these shorter clips made from a longer star talk podcast? I love these short videos but if love to see the longer version if there is one

[@R0bobb1e]

I don't know why, but I knew before they said it that Fe was the Element that would absorb energy instead of releasing energy. As soon as they started talking about it, I though, "Hey, Iron is the one that makes stars go supernova..." but I didn't know why...

Great explanation. I was under the impression that the production of elements beyond helium up to iron happen right at the final minutes/moment of the star. What portion of the stars life is helium to iron?

Please let the next explainer be about what Chuck said in the end :O I just can't understand how all this logical process is pretty much maths. I mean, understanding maths to a certain point I do understand, but I just can't grasp it... It's so fascinating when you guys talk about these phenomena in simple words for everyone to understand!

[@daverobichaud117]

Hi Neil Degrasse Tyson , if iron absorbed fission and fusion then why do they use concrete as a containment barrier such as the nuclear power plant in Japan that collapsed because of the earthquake

[@dahur]

I also believe that because stars come in so many different large sizes, that super heavy elements have been created that don't exist in our solar system. You can only imagine what exotic properties super heavy, maybe even in in the island of stability, elements may possess.

I wish they would have taught this in elementary school when I went , it is where everything came from , I love this show

[@isatousarr7044]

Stars die in a dramatic process influenced by their mass and the balance between gravity and the energy produced by thermonuclear fusion. As stars exhaust their nuclear fuel, fusion reactions slow down, and gravity can cause the core to collapse, leading to various outcomes such as white dwarfs, neutron stars, or supernovae. This fusion, which begins with lighter elements like hydrogen and eventually involves heavier elements, plays a crucial role in creating the elements that make up everything around us, including ourselves. Understanding the interplay of fission and fusion within stars not only explains their life cycle but also the formation of the elements. At what point does the balance between fission and fusion become critical in determining the final stages of a star's life and the resulting cosmic phenomena?

[@jeradsorber]

While fission has been divisive over the years, I really appreciate you bringing us together around fusion in these polarized times

[@gurugauravjoshi]

As far as we know, energy can't be created or extinguished. Energy is in a static state until it is excited. When energy is excited, it transfers into equal energy. Even dark matter (a theory) has mass. You can't reduce mass, all you can do is seperate it.

[@rj66600]

That fact of where atoms for the building blocks of life come from is about the only thing I get spiritual about. It’s just amazing.

[@mcjameson3942]

Thank you so much Neil and Chuck for this wonderful explainer, it's so beautifully done and I loved every bit of it. My only question is - How could such an elaborate and ingenious process come about by chance, with no intelligence responsible for it.

[@OmniphonProductions]

Thanks for explaining the stable equilibrium that occurs within stars, the layering of elements that occurs over time, and the periodic point at which the balance irrevocably shifts. 12:56 - So...if I understand correctly...the Sun started as _just_ hydrogen, while all the astronomical bodies _around_ the Sun are comprised of elements created in _different_ stars. Yes? Follow-up Question: Are all the elements that are _heavier_ than iron created _during_ the collapse, still fusing under the force of gravity, and thus _accelerating_ the absorption of energy?

[@Amprobiuss]

We loove lord nice's public announcements...hats off to the king lord👑

[@SDZ420]

The best on KZbin!❤❤❤♾♾♾

[@ulises5029]

Amazingly easy to understand something SO complex with this kind of explanation. There is just one thing that I didn't get. If a star gets to the point where all of its fuel turned into iron, then it will start to collapse, creating heavier elements but also loosing energy. Does this mean that the star starts getting colder? And if that's the case, then how come it explodes, instead of just turning into a big cold ball of heavy elements floating in space?
