Absolutely amazing resource - thank you for making this freely available to the world and the scientific teaching community. Every university should be donating to you for your efforts.
@@hellothere8675 it's all in how you use/view them. Universities have been a breeding ground of a lot of the social bs that's been going on but the people who apply themselves become some amazing people through higher learning. Unfortunately, people can pay their way into these places and ruin it for many others. Social casts and the state of culture today have made higher learning kind of a joke in a few ways. It's still a beautiful thing.
Yes, it was a blast to watch, absolutely stellar. I was totally absorbed in the explanations, and the visuals were radiant. I found the whole thing superlatively illuminating, and collapsed any uncertainties I had about this type of supernova. Totally blown away XD
This is exactly the level I want science videos to be at! Now give us a serious of videos about each detail in this process! :D Edit: I realised "give us" sound a bit... Demanding. It wasn't. It was just me being eager for more. 😁
The potential for follow up material is boundless. He was microns away from describing the process by which denser than iron elements are made in these explosions. In the fleeting plank lengths of time that the flash of a star’s dying moments occur, exotic elements like gold, plutonium and other dense materials are made, without which there would be no us to wonder at it all. What always blows my mind so completely is that these moments of such utter destruction are also moments of total creation! The very stuff of which life is made possible is produced by the most destructive events known! The Yin and Yang of that is something to ponder.
Yes, that's about right. A light year of lead. But the collapsed core ends up being 1e13 times denser than lead, so a km of such material can block neutrinos.
Honestly when i found this channel, i didn’t focus on subscriber number, toight it was 500k~1m base on the videos and themes, now here i am, with only 17 comments before me. You deserve so much more.
The quality is unbelievable! If he makes a video, I just know it's gonna be good! His video's are among the best there are on the platform. Comparable to even kurzgesagt! In my opinion, his best vid is "How starts die". But they are all so good!
It is the second of november 2021. This channel only has 122k subscribers at the moment. I predict a growth of this channel in the order of magnitude of the core rebound due to the strong force!
Wow! Yep, that bogoggled my mind for sure! The direct Urca process answers a huge lingering question I had about all this. I'm gonna watch this video like 5 more times and be all over Wiki and google armed with powerful new search terms for weeks. Thanks for making this. I wish it were longer. I was glued to that simulation and your visuals (particularly the formation of the shell structure prior to the SN) were beautiful and elucidating as well. PBS Space Time better watch out 'cause you're crushing these topics harder than a collapsing core. I can say that because now I know roughly how hard that is. Bewm!
Couldn't agree more. Such a superb presentation. Interesting that he spells "Urca" as "Erka" in the chapter section, though. I was a bit confused by that.
This is one of the best science explanations and visualizations I have ever seen. Bravo. TH-cam, please recommend this to everyone. This is cutting edge science
I really appreciate that we live in a time when we can watch videos like this that explain these processes in terms of their most elementary components. Visualizing these vast temperatures as exchange of elementary particles is exactly the kind of education Denise to be out there and not just a 'supernova is an exploding star' etc. MORE OF THIS PLEASE!
My brain just went supernova. 🤯 Absolutely phenomenal presentation, though. Definitely the best analytical breakdown of a CC Supernova I've ever seen on this platform. Incredibly well done. Really appreciate you putting this together and sharing it with us. Keep up the amazing work, my friend(s).

"As the silicon layer burns above during the last day of a star's life..." That sentence made me so existentially sad. To think even something as cosmically majestic as a star has a very last day of life...
No reason to be sad seraphim. No you would not exist had a silicon layer not formed above an iron core in the center of a massive star. A bit of time ago. What boggles my mind is that we tripping dancing creatures in a sunlit meadow can hold and understand this in it's mind. It has not been very long that humans had an inkling of how we got here in the last 13 1/2 billion years. What happened before that is subject to a lot of thinking.

This deeper dive into this process gave me such a better understanding of not just supernovae but also how fundamental particles interact, amazing video and series!
This is one of the best explanatory vids I've ever seen on YT... the explanation is exquisite -- this type of explanation and teaching needs to be replicated over and over!
Absolutely incredible video as always! The way you explain things, combined with the gorgeous and intuitively understandable graphics put you in the god tier of science TH-camrs, hands down! Please keep up the great work!
Wow, thanks for going to the next level of depth. We’ve all already seen the usual explanation dozens of times......we know that already. So good to learn new things.
This is quality 👌 I do have one minor correction though... Supernovae are not the most energetic events in the universe. Black hole mergers can radiate several orders of magnitude more energy, and do so in milliseconds rather than months. It's in gravity waves though, so even more ghostly than neutrinos.
the Urca process was super intriguing to see for me. i looked up a few thing and there are so many interesting tidbits about it (the naming alone is top notch) but what i found the intersting was this: i was a bit confused about how the process could pump out so many leptons when the lepton number is supposed to me a conserved quantity; and while one could of course still model it that way i indeed read that lepton number conservation seems to be more of a statistical truth, which made much more sense to me seeing that the Urca process converts something rather statistical in nature (namely thermal energy) to a quantized form of energy.
The lepton number is conserved because the Urca process produces just as many neutrinos as antineutrinos. It doesn't have anything to do with this sort of symmetry breaking. You seem to be mixing up unrelated topics. If you didn't understand the explanation: a neutron decays into a proton, an electron, and an antineutrino (common knowledge hopefully, and the lepton number, and baryon number, are conserved). Then because of electron degeneracy pressure, excess electrons are absorbed by protons, producing a neutron and a neutrino (again, conserving the lepton and baryon number). In reality, there isn't much distinction between this version of the explanation, and just saying that at sufficiently high temperatures, neutrons in an electron degenerate environment will cool down by producing neutrino - antineutrino pairs preferably. That is, they cool down mostly via the weak force, rather than say the electromagnetic force.
This is great. I've always heard the pop science version of what a super nova is and it's always left me with so many question. Incredible video as always and thanks for the answers. (the animations are great too)
The best, most in-depth and clearest description of core collapse supernova I have found anywhere on YT, and although I am no scientist, I am fascinated by the high-energy universe and watch a lot of videos on this subject. Fascinating! Mind blowing! Thanks!
We don't need my little comment to realise how dedicated AND truly gifted our video host has become! Thankyou very much! If I didn't already know this stuff it would have even been better! 🥴👻🚀
Thank you! This answered a years old question of mine, i. e. why we expect gravitational waves from supernovae. As far as I know, gravitational waves need quadrupole and up excitements and I always thought of supernovae being mostly a radial motion thing. with dipole motion being crucial to the process, this makes so much more sense.
i can not fathom the complexity of this... i am amazed by what us humans as a species can achieve in science/knowledge about the universe without using any of our senses to understand it. great video quality, good job
This channel is amazing man...just found it today, and you seriously teach things on a deeper level than other channels, I have watched multiple PBS spacetime on supernovae and I I never knew alot of what you taught here. Straight artisanal man!
This has got to be the most well explained and well animated video on core collapse supernovae in the entire internet or anywhere in the world! I know it is a complex mechanism involving so many different astro/particle physics theories, but this video is so easy to understand and follow that one can fully appreciate how mindbogglinglingling this process is. I hereby award you with my poor man's Nobel Award for best science explanation.
Exactly! That's my another account! After 7 months I'm watching the same video again and stumbled upon my own comment made by me from another account. Hi fellow me!
WOW. It is mind boggling. There are a few things that I couldn’t understand but until this day a haven’t seen any videos on TH-cam or any other platform, that visually explained what happens in the core of massive stars. Thank you!
The channel name is incredibly apt for the topics discussed- I always knew about how supernovas were caused by the core collapsing, but never why that exactly led to the star exploding. This perfectly answered that “but why” question I didn’t even know I wanted answered.
So some stars go fizzle or pop, and some stars go boom. Got it. Very well produced video. Really good graphics, and CG. Narration well spoken, without annoying background music. Extra points for a brief production introduction, and then straight to the subject. I just discovered this channel, and this is the second video I watched. Definitely subscribed and will be watching the rest of video catalog. Highly entertaining.
I've been reading and watching everything I could find about core collapses for probably 10 years. Why is this the first time I've heard about the strong force pushing the core back out to a greater volume? It's really not a difficult concept if you made it that far in the explanation.
You're getting better at this. The way you're choosing to visualize some of these scenes is far clearer, more intuitive, and less "Lol random XD" than your earlier videos. Keep it up, man.
amazing, just AMAZING video. This level of content is incredible, not some "superficial" thing as 99% of youtube videos congrats from Brazil. Really, this is an incredible work that you have done
Why would you assume it's one man creating these? Just because you hear one narrator does not mean there's only one man involved in the production process. Have you gone through your entire life under that impression?
Discovered your channel about a month or 2 ago and love it. Love the way you explain things and the visual representations. That blue figurine buddy has learned a special place in my heart.
I teach astronomy and this is one of the best videos I have seen on supernovae. One correction though, you said that a core collapse supernova is the most energetic events known to science. This is not exactly true. It is one of the most energetic events but is not as energetic as quasars. Some quasars are thought to be merging supermassive black holes and the process can convert up to 30% of the mass in their accretion disk into energy.
Just keep going, dude?! This stuff is hypnotic! Your graphics team deserves an award or two as well. Mesmerising to watch, with a unique quality of tangibility to them that you just don’t get from the graphs and stock footage you see on so many other leading channels of this sciencey nature. I’ll have to watch this one, two or three more times before I fully grasp it all, but it scores an 11 on my fascinate-o’meter (which breaks at 10 btw) so I just have to see more of those beautiful animations and listen to your awe inspired voice telling me all about the biggest, hottest, most mind-alteringly, incomprehensibly vast events in the universe! Thank you.
Why hasn't anyone else taught me anything remotely close to this? There's a reason why I subscribe to you, and even moreso why I religiously have that notification bell turned on and never miss an episode.
Extremely informative video! Not only are the animations really well made, the research and simulations, especially in this video clearly show just how much work is put into making it.
The quality is unbelievable! If he makes a video, I just know it's gonna be good! His video's are among the best there are on the platform. Comparable to even kurzgesagt! In my opinion, his best vid is "How starts die". But they are all so good!
I have to pause the video at two minutes in, to say, that part from about one to one and a half minutes..... Oh! I _finally_ get it! Even after reading and watching countless videos I never quite understood how it ended up layered like that, in the center. Thank you.
Love the line your little character draws simulating you "drawing the line"! I draw the exact same line in my notes to seperate sections. A perfectly not straight squiggly sorta circle back around! Perfect
by far, the best explanation about a supernovae that i ever seen in my entire life! So many questions that i've had coud be answered by you, like how the bounce works. Thank you so much. Subscribed!
Some time ago, I was digesting a lecture about similar topic, very interesting, yet also hard to remember in all the details. I appreciate your ability to produce such a compact, easy to understand and remember summary, really a good job!
This is the first new video I got to watch! I discovered the channel recently last month and have binge watched everything. Thank you for the effort put into these vids-- they are incredibly informative and fun to watch!
I’m no expert in this topic, but I believe you have reached the point at which we see stars producing the more exotic elements, without which there would never have been life in the universe? I’m told that everything from gold to plutonium will suddenly appear in these explosions, due to the immense heat, pressures and asymmetric nature of the blasts. I would love to see a video about that? About what the explosions do in the universe and how their effects are all but infinite in their ability to effect almost every other region of spacetime? At this moment, astronomers are witnessing light from such explosions, occurring billions of years ago, almost unimaginable distances from us, creating the building blocks for complex organisms. Acts of creation out of destruction, both of which truly do boggle my tiny mind. Wonderful show, sir. I love your tongue tied appreciation and wonder. Much like my own.
Wanted my teachers to explain why neutron could keep protons close to each other........suspect no one really knew when i asked in '61...........thank-you for your presentation!!
Deep respect for the amount of detail and the pointers to more information. I'd heard that stalling shockwaves were a theoretical problem, but hadn't heard of any of the theories for why they un-stall.

So well done with just the right amount of rigor to both entertain and inform.
We don't need my little comment to realise how dedicated AND truly gifted our video host has become! Thankyou very much!
If I didn't already know this stuff it would have even been better! 🥴👻🚀
Probably the best explanation of this event yet done. Thank you very very much, I am waiting for your further intrigues on this topic.
Thank you! This answered a years old question of mine, i. e. why we expect gravitational waves from supernovae. As far as I know, gravitational waves need quadrupole and up excitements and I always thought of supernovae being mostly a radial motion thing. with dipole motion being crucial to the process, this makes so much more sense.
this guys uploads and i gotta drop everything to watch these amazing videos
This is the best illustration of a supernova I've ever seen
Thank you and thank you to everyone who donated to you.
i can not fathom the complexity of this... i am amazed by what us humans as a species can achieve in science/knowledge about the universe without using any of our senses to understand it. great video quality, good job
The intro to this is what finally made me grok the significance of iron as the final fusion step. Nothing ever explained it adequately before. Thanks!
This channel is amazing man...just found it today, and you seriously teach things on a deeper level than other channels, I have watched multiple PBS spacetime on supernovae and I I never knew alot of what you taught here. Straight artisanal man!
This has got to be the most well explained and well animated video on core collapse supernovae in the entire internet or anywhere in the world! I know it is a complex mechanism involving so many different astro/particle physics theories, but this video is so easy to understand and follow that one can fully appreciate how mindbogglinglingling this process is. I hereby award you with my poor man's Nobel Award for best science explanation.
Never in my life I've seen someone explaining supernova at this level of detail...!!!
Exactly! That's my another account! After 7 months I'm watching the same video again and stumbled upon my own comment made by me from another account. Hi fellow me!
WOW. It is mind boggling. There are a few things that I couldn’t understand but until this day a haven’t seen any videos on TH-cam or any other platform, that visually explained what happens in the core of massive stars.
Thank you!
Mindboggling indeed! But also incredibly fascinating.
Thanks for making thse videos.
Extremely well presented, thanks a lot for your effort!
The channel name is incredibly apt for the topics discussed- I always knew about how supernovas were caused by the core collapsing, but never why that exactly led to the star exploding. This perfectly answered that “but why” question I didn’t even know I wanted answered.
So some stars go fizzle or pop, and some stars go boom. Got it.
Very well produced video. Really good graphics, and CG. Narration well spoken, without annoying background music. Extra points for a brief production introduction, and then straight to the subject.
I just discovered this channel, and this is the second video I watched. Definitely subscribed and will be watching the rest of video catalog. Highly entertaining.
This explanation of what happens in these extreme circumstances in physics of stars is exactly what I wanted explained to me for so long. Thank you
I've been reading and watching everything I could find about core collapses for probably 10 years.
Why is this the first time I've heard about the strong force pushing the core back out to a greater volume? It's really not a difficult concept if you made it that far in the explanation.
You're getting better at this. The way you're choosing to visualize some of these scenes is far clearer, more intuitive, and less "Lol random XD" than your earlier videos. Keep it up, man.
This is honestly my new favorite explainer TH-cam.
Best explications of more advanced topics on the internet, with amazing visuals! Thank you!
I got a wiff of how a supernova worked some 10 years ago but left more questions than answers.
Thanks.
Will watch again.
amazing, just AMAZING video. This level of content is incredible, not some "superficial" thing as 99% of youtube videos
congrats from Brazil. Really, this is an incredible work that you have done
this video really helped me understand this better, thank you
you made this in such a way that it explained a lot of complex stuff I knew about from crash course astronomy even better
Someone explain to me how this one man is able to create animations better than literally anything made by National Geographic ever
Why would you assume it's one man creating these? Just because you hear one narrator does not mean there's only one man involved in the production process. Have you gone through your entire life under that impression?
Discovered your channel about a month or 2 ago and love it. Love the way you explain things and the visual representations. That blue figurine buddy has learned a special place in my heart.
I teach astronomy and this is one of the best videos I have seen on supernovae. One correction though, you said that a core collapse supernova is the most energetic events known to science. This is not exactly true. It is one of the most energetic events but is not as energetic as quasars. Some quasars are thought to be merging supermassive black holes and the process can convert up to 30% of the mass in their accretion disk into energy.
Just keep going, dude?! This stuff is hypnotic! Your graphics team deserves an award or two as well. Mesmerising to watch, with a unique quality of tangibility to them that you just don’t get from the graphs and stock footage you see on so many other leading channels of this sciencey nature.
I’ll have to watch this one, two or three more times before I fully grasp it all, but it scores an 11 on my fascinate-o’meter (which breaks at 10 btw) so I just have to see more of those beautiful animations and listen to your awe inspired voice telling me all about the biggest, hottest, most mind-alteringly, incomprehensibly vast events in the universe! Thank you.
Why hasn't anyone else taught me anything remotely close to this?
There's a reason why I subscribe to you, and even moreso why I religiously have that notification bell turned on and never miss an episode.
Wonderful explanation of "star goes boom" ... thank you.
Extremely informative video! Not only are the animations really well made, the research and simulations, especially in this video clearly show just how much work is put into making it.
The quality is unbelievable! If he makes a video, I just know it's gonna be good!
His video's are among the best there are on the platform. Comparable to even kurzgesagt!
In my opinion, his best vid is "How starts die". But they are all so good!
Love how you make complex ideas easy to understand
That's a lot of fresh info crammed into a very short video. Well done!
I have to pause the video at two minutes in, to say, that part from about one to one and a half minutes..... Oh! I _finally_ get it! Even after reading and watching countless videos I never quite understood how it ended up layered like that, in the center. Thank you.
I honestly love this channel so much
Such a great explaination! Thank you so much
these videos are the best science videos on youtube. and it is not even close
This answered SO many questions I've had. I love astrophysics. This channel as well, so well explained
Love the line your little character draws simulating you "drawing the line"! I draw the exact same line in my notes to seperate sections. A perfectly not straight squiggly sorta circle back around! Perfect
by far, the best explanation about a supernovae that i ever seen in my entire life! So many questions that i've had coud be answered by you, like how the bounce works. Thank you so much. Subscribed!
Some time ago, I was digesting a lecture about similar topic, very interesting, yet also hard to remember in all the details. I appreciate your ability to produce such a compact, easy to understand and remember summary, really a good job!
Every video gets better and better. So awesome.
I laughed at the Direct Urka Process animation, well done, informative and entertaining
Like the stars in the background, a glittering, stellar presentation.
Thank you🌹.
Best visuals and animations, and stellar explanations
This is the first new video I got to watch! I discovered the channel recently last month and have binge watched everything. Thank you for the effort put into these vids-- they are incredibly informative and fun to watch!
I’m no expert in this topic, but I believe you have reached the point at which we see stars producing the more exotic elements, without which there would never have been life in the universe? I’m told that everything from gold to plutonium will suddenly appear in these explosions, due to the immense heat, pressures and asymmetric nature of the blasts. I would love to see a video about that? About what the explosions do in the universe and how their effects are all but infinite in their ability to effect almost every other region of spacetime? At this moment, astronomers are witnessing light from such explosions, occurring billions of years ago, almost unimaginable distances from us, creating the building blocks for complex organisms. Acts of creation out of destruction, both of which truly do boggle my tiny mind. Wonderful show, sir. I love your tongue tied appreciation and wonder. Much like my own.
Wanted my teachers to explain why neutron could keep protons close to each other........suspect no one really knew when i asked in '61...........thank-you for your presentation!!
It seems there are quite a few more details about supernovae that I've never heard of. Great video
Deep respect for the amount of detail and the pointers to more information. I'd heard that stalling shockwaves were a theoretical problem, but hadn't heard of any of the theories for why they un-stall.
Thrilled you're over 100k subs! Love this channel, thank you for taking the time to make such clear videos
Idk how im just discovering your channel, this is quality stuff! Great work, cant wait to dig into your videos tomorrow!
I was not expecting that Veritasium cameo
More of a screen shot really. That would be cool though if Derek stopped by at some point though. You never know, it could happen.
@@whatelseison8970 totally agree
Dang. I’ve never seen supernovas been explained in this much detail before. I’ve always only seen mild simplifications, until now.
looking forward to all your future vids, I really enjoy your content
