I have beeb worried for your well-being for rare inactivity on RUclips, Sir. You are the true mentor for me since you carefully choose every exact word in laymen's terms in each and every of your contents. I always rewatch your video about time-travelling whenever I am too down or sad with the losses uncontrollable, and emphasise the core message you gave in that one. I really hope to meet you in person to be able to tell you how your RUclips videos deeply affect on one's life and thank you. Take care, Sir.
Wow that's so kind of you to share. Really means a lot to hear things like this. Yes it's sometimes hard balancing everything in my life to make these, but you guys keep me going
@@CoolWorldsLabWow didn't expect a reply on such short notice, Sir. Please keep on doing these knowledgable and creative contents since there is less and less real science channels, and more and more pseudoscience or Ancient Alien channels out there.
Between you guys, PBS Space Time, and SEA, there's arguably enough ridiculously high quality & comprehendible content available on astrophysics that it makes these kinds of cutting edge developments within the field relatively accessible to those of us who enjoy learning about it but aren't academics. Thank you for qll that you and your team do, we truly appreciate your time and dedication to communicating the science! 🙏
I'd like to add History of the Universe, and Astrographics to your list! As well as non space stuff like Be Smart, Veritasium, PBS Eons, SciShow, Voices of the Past, Fall of Civilizations, and Real Science. So much great interesting educational stuff out there it's hard to keep up.
@@iGramage those are actually pretty much the rest of my list of channels that I'm subscribed to all notifications from 😅 great additions to the list!! 👍
Mr Cool Worlds- man I feel the same how much it means that you choose your words the way you do and are able to make these concepts easier to fully grasp. I absolutely love the subject matter of your channel as a whole and it’s been a real pleasure watching your videos and gaining a measure understanding I hadn’t had before doing so
Watching and learning from these videos has taught me to be observant about things in the universe. Like when Dr. Kipping goes from wearing a T-shirt while on-screen speaking into the mic. To completing the sentence on-screen speaking into the mic, now with jacket on. This guy is a God.
This channel is a must-go for every astronomy friend. Not as bombastic as some TV documentaries, yet still understandable even for us, amatures and enthusiasts.
@@CoolWorldsLabIn regards to FTL communication using entanglement what do you think about this idea? There is one piece of information we can send and measure on both sides accurately using entanglement, TIME. Or more specifically TIME intervals. How about we assign letters and numbers to each second that passes by between measurements? Same for punctuation marks? Use the first measurement as the signal for the person receiving the message to begin counting then count the seconds until the next measurement. We assign letters and numbers to each moment of time that passes by beforehand using that as our “key” that we give to both the sender and the receiver. So if 1 second elapses between the 1st and the 2nd measurement that equals the letter A. If 2 seconds pass by then it's the letter B. First “ping” or measurement is the starting point and the second ping is the end point. Count the time interval in between and refer to a “key” to find out what letter or number that time interval represents. We can write sentences this way. And just ignore the spins altogether. As long as both observers have the same "key", wouldn't that work? Would just need a ton of entangled particles as some have stated that once you interact with an entangled pair, that breaks the entanglement. We would basically be using 2 entangled pairs to spell out one letter. Use one entangled pair as the starting point and another entangled pair as the end point for the count. Then wait a minute between each letter we’ve sent as a reset before we send the next letter and repeat until a word is spelled out.
Dr. Kipping, you are seriously the best astronomy and physics journalist I have ever come across (and I consume a lot of that content.) Thank you for being the adult in the room about strangelets/strange matter, for the truly curious, the truth is always more interesting than any fiction. Plus, I can pencil cross off the existential dread of the strangelet apocalypse. Every video you release makes my world just a little cooler, thanks!
As an aspiring Astrophysicist, I really enjoy these videos! Neutron Stars are so interesting not only due to their characteristics, but because a select few are very close to that 3 SM boundary. Studying those few could help refine existing boundary estimates, and give a greater understanding on the limits of matter at those insane pressures. Which is super exciting.
I like that you give credits for clips and even link RUclips channels for clips in the video. It is a good example that others on RUclips should follow.
Just 2 minutes in and this is incredible!! I just love your style in narrating these amazingly crafted videos! You have a real talent for explaining such complex topics in great detail and the effort you put into making these vids really pays off😄👍 these bizarre cosmic objects are explained so well by you which makes it so much easier to comprehend how this universe works (not an easy task!😂), Love this content, please keep it up as its greatly appreciated!!! ❤😊 Man this universe is so unbelievablely strange.
Thanks so much David. The podcasts are fascinating too! Nothing else quite like this channel, the level of detail and depth is perfect for curious adults with an existing interest in astronomy and astrophysics. Thanks for spreading the knowledge.
The refinement of these videos is astonishing. I cannot believe you do not have millions of followers. This has become my favorite YT channel bar none. Amazing work, please don’t ever stop!
This explanation of the stability of strange matter, using quantum states and the Exclusion Principle, is much clearer than most other RUclips videos I've seen on the subject. The transformation of "normal" matter into strange matter is likewise more clearly detailed. I'm a recreational math and physics nerd over 50 and I wish I'd gotten inspired into pursuing number theory and theoretical physics when my brain was younger... but RUclips didn't exist then. Thank you for these videos.
Always a good day when our guy posts a new video. A great topic too. Thanks for these videos, David. Considering your high production value I imagine they are quite a bit of work. Hope you and your family have a great holiday!
I have always found neutron stars more fascinating than black holes because we actually kind of know what is going on inside them. And they do not disappoint. Definitely my favorite objects in space. I just wish we had was a really clear picture of one in multiple wavelengths so we could see the surface.
There have been some pictures of neutron stars surface emission by Hubble, and a few years ago, a team of scientists was able to map the surface of one.
@@jhtrq1465 I did a search before I wrote that comment, just to make sure there wasn't something new but I didn't see that. Do you know where you saw it?
@@Nefville I think they were referring to this - www.nasa.gov/universe/nasas-nicer-delivers-best-ever-pulsar-measurements-1st-surface-map/ which is the NICER telescope being used to observe and attain certain measurements of a close by pulsar. However, to say they actually mapped the surface of a pulsar is misleading, as they observed and mapped temperature hot spots. P.s. Neutron stars are also my favorite 🥰
Finally! I've been waiting for a good explanation of strangelets and why they would be so catastrophic, considering strange quarks aren't all that common in the universe. How could something so uncommon become so prevalent all of a sudden? This video finally explains the mechanism. Yes, I first saw the video about strangelets and strange stars on Kurzgesagt a few years ago, but that just left me with more questions.
@@CoolWorldsLab are there theories about other heavy quark hadrons that can become metastable if surrounded by more of its kind, like charmed, top or bottom quarks?
David, I know you are busy with work as well but if I could be selfish for just second here I wish you would post content more frequently 🙏 ….. I absolutely, thoroughly enjoy your videos! It has reignited my love for all things astronomy ❤ Thank you so very much for this!!! Edit: Grammar error 😉

Thank you for your latest upload, I'm just a simple heating engineer and struggle to understand many subjects surrounding space etc. You have a brilliant ability to simplify this subject so the simple man can even enjoy it. Many thanks 👍❤️🏴
New Cool Worlds video, let’s gooo!! Your work on life’s early start and our late arrival made me consider on the universal scale, 14 billion years may seem like a long time but if stars are going to continue being formed for trillions of years we seem pretty early on the cosmic timeline.
Mr Kipping, you are to me one of the most amazingly intelligent and interesting human being I have ever encountered, even if it's only virtually here, I have a very deep admiration for you Sir. Thank you so much for everything you do. 🙏🏻
If the strange matter is so much more dense than regular quark matter, what would stop it from forming an event horizon and becoming a black hole once it consumed enough ordinary matter? It doesn't sound like it's a case of "if this touches you, you turn into strange matter and it bounces off to convert more" but more like "it turns you into strange matter as it sucks you in." Nothing more worrisome than the existence of black holes.
An absolutely wonderful video. Thank you for taking time to create content for us! Please do a video about the LISA mission (Laser Interferometer Space Antenna), if you ever get a chance!
You've done it again, Dr Kipping. You've blown me away. I can hardly imagine how exciting it must be for your students at Columbia. By the way, how is the search for Exomoons progressing?
Love your videos! The combination of great science, great philosophy and great production value is top tier. Thanks so much for making these I was curious, I love the poster on your wall on the left side of the screen at 0:41 and I'd love to get one of my own! Is there anything you can tell me about it to point me in the right direction to get one? I've been obsessing over it for a while and just keep forgetting to ask
I spend most of my days terrified that this is it, I’m gonna walk out my garage and look to the left to see a horizon being turned into a grey goo. Clouds falling from the sky turned from white fluff to grey glop falling into trees that crumble and splash into the same grey goo as it engulfs all the houses in front of me everywhere, everything turning into grey goo. I see a young couple pushing a stroller with 2 Great Danes that are freaking out turned into grey goo as they scream no more. Then it’s my turn as the last thing I see is my legs splash away and I fall into the goo and it all goes grey. I don’t die but become one with the cosmo and all that was consumed by the strange matter. Any second now earth will smack into an errant piece of strange matter ejected from a neutron star 2.3 billion years ago.
Love you videos! Even though I am already deeply fascinated by the stars, space-time, yadda, yadda.. But, you always have me gripping with even more intrigue, every single time. Everything blends so well. Hope all is well! And thanks again!
This was mindblowing and insanely cool to learn about! I like to take my time and REALLY listen, when it comes to "matters" like these (:P), and I find myself rewinding entire sentences, over and over again - to ask myself; "Did he just say THAT?!" - and I love how learning new stuff makes me feel that way. Like, for instance, that most of the gold on earth is a product of the merger of binary neutron stars.. Like... WHAT?! That is SO DAMN COOL! I love it. Thank you for the beautiful knowledge. You have humility, and your presentation doesn't require viewers to be at Mensa level to understand - so thank you for putting this knowledge into easily digestible sentences (although, I still pause the video every time I hear a new alien word like "hyperon", lol) Looking forward to learn more!
@@CoolWorldsLabspeak for yourself. I've given up pretending, I'm very strange. Neutron and quark stars are something I'd wanted to learn more about (just for the hell of it, of no practical use to a bioscientist) and you are one of the better physics communicators.
Thank you for approaching this discussion in a factual manner and not - as you stated - sensationalising it as RUclips does. This was very interesting, educational, and thought-provoking. Thank you. Subscribed.
LOL... "factual" manner about a purely theoretical/hypothetical unproveable "speculation"... BELIEVE THE SCIENCE... 😉... Star Trek is real... in someone's mind...
Much appreciate another fine and fairly cutting edge video (at least in lay terms), and thank you for not going too far off on the strange matter red-herring when discussing the stellar journey on becoming a black hole.
Thanks for this fascinating dive into neutron stars, quark stars, and strangelets! I much prefer this sort of (as you called it) "sober" take on the theory, which overcomes clickbait degeneracy pressure, to move from a metastable sensationalist state to this more informative and stable state. If you happen have a moment, I did have a couple of questions about the electrical charge of strangelets: 1. Suppose (for the sake of discussion) that a negatively-charged strangelet were here on Earth, somehow. How would it be able to overcome the negative electric charge of the electron cloud surrounding an atom of ordinary matter in order to interact with the neutrons and protons in its nucleus? 2. Suppose a negatively-charged strangelet encounters a neutron. Then (if I am understanding this correctly) one of the neutron's two down quarks will settle into a lower-energy state and become a strange quark, thus converting the neutron into more of the same strange matter that comprises the strangelet. But what happens when the negatively-charged strangelet interacts with a positively-charged proton? Is the charge of the quarks in the proton conserved? And, if not: what happens to the positive charge of the up quarks in the proton--would they eventually increase the charge of the strangelet, until it is no longer negatively charged?
Just want to say thanks for your channel. There are a lot of channels out here posing as science astronomy channels, but many range from poorly researched to flat out pseudoscience. It's awesome that passionate academics, like yourselves, are putting these out for us lay people. The science community really needs to do more of this, in general, for all fields.
The fact that this channel does not sensationalize and over-dramatize things is the reason I click every single video and I've got full notifications enabled. THIS is what we need, not some random Ridddle videos that are unscientific and just try to milk views by sensationalizing and giving false information. It's quite similar to negatively charged strangelets, actually. Yet Cool Worlds is an even more stable form of matter, and I'd call it truthium. It consists of well-researched physics and somehow it attracts me way, WAY harder than "negatively charged strange videos". It's an honor and a priviledge to watch your videos, Professor Kipping.
I've only recently heard of the Quark Star. It showed up in a curiosity search for ideas related to the Hypothetical Seventh Quark. There's a growing number of Theoretical Physics folk saying things like: "a three dimensional object needs a Seventh Quark to generate a repulsive force keeping matter from collapsing altogether." Or something akin to That. I'm seriously lousy at mathematics, so, I'm unable to work on The quantum physics formulae presented by Such Folk. But, in your dazzling laymen's terminology presentation, here, I think they're on to a similar notion regarding the pressures preventing high mass neutron stars from collapsing into black holes. They're also suggesting that Gravity is An Effect, rather than a Thing and thusly, lacks Any specific Particle of Its own. That The so-called "Graviton" So widely used in science fiction stories, might NOT actually exist in Reality! It Does make sense with this Quark Star theory. Because: if you have gravitons at the pressures suggested for Quark Stars, they'd interact with Quarks striving to avoid being separated from one another! Of course, most of what I understand about This sort of thing IS mainly its use As plot devices in science fiction stories!🤪🥴 Do Gravitons, Actually, Exist? And, If So; Do they have any effects on the formation of a Quark Star? Because: the stuff I've stumbled across in this subject sounds like Gravitons would cause high mass neutron stars to Form into Black Holes instead of creating Quark Matter! And, they also suggest that everything is composed of "Quantum Fields" something akin to String Theory! 🥴 Whatever, it's a fascinating exploration, to be Sure 💖
It’s just nice when instead of destroying the universe, astrophysics ends up making us feel a little more safe and secure in a cosmos that doesn’t like us. Thanks for another amazing episode.
Yes! I hear you man. I don’t mind being alone either. A learned state of being. I love your science content, but I will admit to losing hope for/in humanity. I got it back listening to Agro Squirrel narrates. He narrates short Sci-Fi stories that gives me hope for humanity again. Stay safe
"Clearly, negatively charged strange matter would have disastrous consequences for any ordinary matter it touches. It probably could not be tolerated at any level on earth or in ordinary stellar environments."
This was a really interesting video. The worldbuilding for a sci-fi story I'm working on uses positively-charged strangelets as a super dense material for various uses and specifically bans the production of negatively-charge strangelets because of the danger of converting everything if any got out. It was great to hear a super concise description of how they would work theoretically.
Prof. Kipping, your hypothesis about quark stars being an inevitable part of the evolution of neutron stars is logically sound from a material science perspective. As temperature (thermal energy) is radiated away density increases. From that, it is reasonable to conclude that as neutron stars cool and their density increases this leads to a slow progression of quark core formation as a neutron star cools. I hope you don't mind me giving my thoughts on your hypothesis Prof. Kipping, I love your content and your work, especially your work on exomoons. Please keep up the great work.
But it is not. Degeneracy pressure has to do with the physical size of quantum states, and is not sensitive to temperature. When a degenerate object cools to 0K, it’s the same size with a completely full Fermi sea.
@DrDeuteron degeneracy pressure isn't affected by temperature. You are correct. However, it is affected by density, which in turn is affected by temperature. So, while temperature has no direct effect on the degeneracy pressure, the density increase as a result of the dissipation of thermal energy does have a direct effect on the degeneracy pressure. The cycle is scientifically sound, somewhat unprovable, like string theory or many worlds, but scientifically, it is sound.
“That which does not Degenerate you, makes you Stranger” One of your best videos! Which is saying something as you consistently deliver outstanding discussions and ideas on the amazing world of astrophysics (and beyond).
"thank you for uploading these videos. Even if I'm having a hard night, I just put a relaxing astronomy video on and listen. It always makes my nights go much easier. Thank you!!!"
Great video, clearly explains the science without relying too much on analogies. I’ve heard about quark stars before but hardly ever seen any good explanations- thank you. (But does quark rhyme with hark or hawk?!)

Even though I only understand a tenth, if that, of what David is talking about I always find his videos so fascinating.
Always excited when I see an upload by you 😎
excited to see this video, thanks for your hard work!!
Oh my god that closing message almost made me cry
Easily the most fair exchange for 26 minutes of my life ever. Brilliant presentation!
you're an amazing orator and educator. i was always interested in astronomy, but i know way more about it thanks to your content.
I spend most of my days terrified that this is it, I’m gonna walk out my garage and look to the left to see a horizon being turned into a grey goo. Clouds falling from the sky turned from white fluff to grey glop falling into trees that crumble and splash into the same grey goo as it engulfs all the houses in front of me everywhere, everything turning into grey goo. I see a young couple pushing a stroller with 2 Great Danes that are freaking out turned into grey goo as they scream no more. Then it’s my turn as the last thing I see is my legs splash away and I fall into the goo and it all goes grey. I don’t die but become one with the cosmo and all that was consumed by the strange matter. Any second now earth will smack into an errant piece of strange matter ejected from a neutron star 2.3 billion years ago.
My first visit here. 42 seconds in. Subscribed. Original content, bearable voice, but above all, decent quality of science.
I don’t understand a tenth of this, but Dr. Kipping’s voice is so…mesmerizing I keep listening.
I loved the video. Thank you for sharing this wonderful and fascinating video. It really made my day so much better.
Thanks
👍
Thank you for this beautiful, amazing, deeply informative, well-articulated, well-organized, and well-edited video.
Imagine what school/uni would be like if all your professors where as inspirational as Sir Coolworlds 😊
Love you videos! Even though I am already deeply fascinated by the stars, space-time, yadda, yadda.. But, you always have me gripping with even more intrigue, every single time. Everything blends so well. Hope all is well! And thanks again!
Sensational, as always. The best astronomy/cosmology channel on youtube by a country mile. Thanks so much.
This was mindblowing and insanely cool to learn about! I like to take my time and REALLY listen, when it comes to "matters" like these (:P), and I find myself rewinding entire sentences, over and over again - to ask myself; "Did he just say THAT?!" - and I love how learning new stuff makes me feel that way. Like, for instance, that most of the gold on earth is a product of the merger of binary neutron stars.. Like... WHAT?! That is SO DAMN COOL! I love it.
Thank you for the beautiful knowledge. You have humility, and your presentation doesn't require viewers to be at Mensa level to understand - so thank you for putting this knowledge into easily digestible sentences (although, I still pause the video every time I hear a new alien word like "hyperon", lol)
Looking forward to learn more!
It’s always a good day when Cool Worlds uploads!
It is astonishing that here is so much detail about the inner layers of such remote objects
i regrettably always forget about this channel but its always a great surprise to see space science daddy
If nobody else will do it, i will. This episode was very strange.
RUclips would be empty without Dr Kipping and this channel.
We’re all a little strange…
@@CoolWorldsLabspeak for yourself. I've given up pretending, I'm very strange. Neutron and quark stars are something I'd wanted to learn more about (just for the hell of it, of no practical use to a bioscientist) and you are one of the better physics communicators.
Another wonderous video.. I loved every minute. Thank you for what you do!
Thank you for approaching this discussion in a factual manner and not - as you stated - sensationalising it as RUclips does. This was very interesting, educational, and thought-provoking. Thank you. Subscribed.
LOL... "factual" manner about a purely theoretical/hypothetical unproveable "speculation"... BELIEVE THE SCIENCE... 😉... Star Trek is real... in someone's mind...
Absolutely loved this video!
This all suggests that you could get the most impressive Nobel ever, for proving that we'll all be dead soon.
Very informative and well produced .
Much appreciate another fine and fairly cutting edge video (at least in lay terms), and thank you for not going too far off on the strange matter red-herring when discussing the stellar journey on becoming a black hole.
Thanks for this fascinating dive into neutron stars, quark stars, and strangelets! I much prefer this sort of (as you called it) "sober" take on the theory, which overcomes clickbait degeneracy pressure, to move from a metastable sensationalist state to this more informative and stable state.
If you happen have a moment, I did have a couple of questions about the electrical charge of strangelets:
1. Suppose (for the sake of discussion) that a negatively-charged strangelet were here on Earth, somehow. How would it be able to overcome the negative electric charge of the electron cloud surrounding an atom of ordinary matter in order to interact with the neutrons and protons in its nucleus?
2. Suppose a negatively-charged strangelet encounters a neutron. Then (if I am understanding this correctly) one of the neutron's two down quarks will settle into a lower-energy state and become a strange quark, thus converting the neutron into more of the same strange matter that comprises the strangelet. But what happens when the negatively-charged strangelet interacts with a positively-charged proton? Is the charge of the quarks in the proton conserved? And, if not: what happens to the positive charge of the up quarks in the proton--would they eventually increase the charge of the strangelet, until it is no longer negatively charged?
Who knows .
Just want to say thanks for your channel. There are a lot of channels out here posing as science astronomy channels, but many range from poorly researched to flat out pseudoscience. It's awesome that passionate academics, like yourselves, are putting these out for us lay people. The science community really needs to do more of this, in general, for all fields.
Thanks so much, Tim. Doing both isn’t easy but I think such voices are important
The fact that this channel does not sensationalize and over-dramatize things is the reason I click every single video and I've got full notifications enabled. THIS is what we need, not some random Ridddle videos that are unscientific and just try to milk views by sensationalizing and giving false information. It's quite similar to negatively charged strangelets, actually. Yet Cool Worlds is an even more stable form of matter, and I'd call it truthium. It consists of well-researched physics and somehow it attracts me way, WAY harder than "negatively charged strange videos".
It's an honor and a priviledge to watch your videos, Professor Kipping.
Thanks so much! I know we probably take a hit on views doing it this way but I feel passionately about a balanced, evidence based approach.
I've only recently heard of the Quark Star. It showed up in a curiosity search for ideas related to the Hypothetical Seventh Quark. There's a growing number of Theoretical Physics folk saying things like: "a three dimensional object needs a Seventh Quark to generate a repulsive force keeping matter from collapsing altogether." Or something akin to That. I'm seriously lousy at mathematics, so, I'm unable to work on The quantum physics formulae presented by Such Folk. But, in your dazzling laymen's terminology presentation, here, I think they're on to a similar notion regarding the pressures preventing high mass neutron stars from collapsing into black holes. They're also suggesting that Gravity is An Effect, rather than a Thing and thusly, lacks Any specific Particle of Its own. That The so-called "Graviton" So widely used in science fiction stories, might NOT actually exist in Reality! It Does make sense with this Quark Star theory. Because: if you have gravitons at the pressures suggested for Quark Stars, they'd interact with Quarks striving to avoid being separated from one another! Of course, most of what I understand about This sort of thing IS mainly its use As plot devices in science fiction stories!🤪🥴
Do Gravitons, Actually, Exist? And, If So; Do they have any effects on the formation of a Quark Star? Because: the stuff I've stumbled across in this subject sounds like Gravitons would cause high mass neutron stars to Form into Black Holes instead of creating Quark Matter!
And, they also suggest that everything is composed of "Quantum Fields" something akin to String Theory! 🥴
Whatever, it's a fascinating exploration, to be Sure 💖
Another brilliant episode...I love these programmes by David and the crew..
I particularly enjoyed the 1G drive episode....
Keep up the great work 👍
It’s just nice when instead of destroying the universe, astrophysics ends up making us feel a little more safe and secure in a cosmos that doesn’t like us. Thanks for another amazing episode.
Yes! I hear you man. I don’t mind being alone either. A learned state of being. I love your science content, but I will admit to losing hope for/in humanity. I got it back listening to Agro Squirrel narrates. He narrates short Sci-Fi stories that gives me hope for humanity again.
Stay safe
"Clearly, negatively charged strange matter would have disastrous consequences for any ordinary matter it touches. It probably could not be tolerated at any level on earth or in ordinary stellar environments."
This was a really interesting video. The worldbuilding for a sci-fi story I'm working on uses positively-charged strangelets as a super dense material for various uses and specifically bans the production of negatively-charge strangelets because of the danger of converting everything if any got out. It was great to hear a super concise description of how they would work theoretically.
Thank you Dr. Kipping your channel is absolutely mind boggling!
those quarks making buddies looked like a magic trick 🧙🏻♂️✨
Please keep keeping it real. No sensational click bait. Please don't change your style. I've learned a lot from you professor Kipping. ❤
Keep the good work going David 👍🏻
Love this channel so much ❤
An interesting question for sure, hopefully theoretical advances in future will help shed more light on which scenarios are the most likely here.
Hilarious video clips. Wonderful video. Thank you, professor!
Prof. Kipping, your hypothesis about quark stars being an inevitable part of the evolution of neutron stars is logically sound from a material science perspective. As temperature (thermal energy) is radiated away density increases. From that, it is reasonable to conclude that as neutron stars cool and their density increases this leads to a slow progression of quark core formation as a neutron star cools. I hope you don't mind me giving my thoughts on your hypothesis Prof. Kipping, I love your content and your work, especially your work on exomoons. Please keep up the great work.
But it is not. Degeneracy pressure has to do with the physical size of quantum states, and is not sensitive to temperature. When a degenerate object cools to 0K, it’s the same size with a completely full Fermi sea.
@DrDeuteron degeneracy pressure isn't affected by temperature. You are correct. However, it is affected by density, which in turn is affected by temperature. So, while temperature has no direct effect on the degeneracy pressure, the density increase as a result of the dissipation of thermal energy does have a direct effect on the degeneracy pressure. The cycle is scientifically sound, somewhat unprovable, like string theory or many worlds, but scientifically, it is sound.
Best description of quark stars and strange matter that I've seen.
Always anticipating your videos, keep up the great work! hope you join Threads too
“That which does not Degenerate you, makes you Stranger”
One of your best videos! Which is saying something as you consistently deliver outstanding discussions and ideas on the amazing world of astrophysics (and beyond).
Bravo my friend. Great show. Thank you very much.
"thank you for uploading these videos. Even if I'm having a hard night, I just put a relaxing astronomy video on and listen. It always makes my nights go much easier.
Thank you!!!"
Someone just recommended this channel to me on Reddit now im hooked
Really enjoyed your video, really well though and put together. Subbed.
Thank you for not sensationalizing this topic and exploring it in a professional manner.
Thanks for your videos, I enjoy them a lot
Always looking forward to your content. Thank you.
Great video, clearly explains the science without relying too much on analogies. I’ve heard about quark stars before but hardly ever seen any good explanations- thank you. (But does quark rhyme with hark or hawk?!)
Brilliant video
thank you for your channel...really enjoy your work..from Ireland
👍
