We’ve traveled to lots of weird places on this show - from the interiors of black holes to the time before the big bang. But today I want to take you on a journey to what has got to be the weirdest place in the modern universe - a place where matter exists in states I bet you’ve never heard of. Today we take a journey to the center of the neutron star.

Neutron stars are my favorite topic in stellar physics. But now, for the first time, I can say, with conviction, that they are the most tortured corpses in the universe. You have a new subscriber. You even mentioned The Pauli Exclusion Principal which was inevitable. Great video!
@luthermcgee3767
Whoa! That's the best description of a neutron star. " ..the most tortured corpses in the universe." I don't know if that's your expression or if it's been around but it's the first time I've read it. Cool. I'm going to write a song called, "I'm a Neutron Star." It's going to be a song about a well-liked person who has a personality that shines. Yet, for a long time, deep inside, he's always been a tortured soul.
@@libraryquiet , wow! I'd like to see it when it's completed.
I'd always imagined that the surface of a neutron star would be the smoothest surface in the universe. After all, a ball of chromed steel is pretty granular by comparison with its volume some 10k greater than a ball of nuclear matter.
Reminds me of the Rick & Morty scene about "total flatness".
How did PBS get blessed with such a great host? Seriously Matt is so awesome. Cheers!
old host had to go away, matt took his place. old host was pretty good so everyone was worried, but matt blew us out of the water by being even better.
@@GraveUypo Yup, nO'Dowd about it!
It's interesting you like him, I prefer Phil Plait. His role hosting CrashCourse Astronomy is a few years old now, but I love his passion, his warm diction and find him more engaging than Matt Dowd.
For some reason I feel exactly the opposite.
@@Herkimer_Snerd perhaps you two could explore a superposition of preference -- they are both excellent in their own ways!
Neutron stars call me the most extreme carbon in the universe.

Oh, no. Thank yourself.

Too political
@rezzer7918 don't fing watch it then donkey
At the start of the video I was like "oh please Matt, states of matter I've never heard of, I've been watching this channel long enough of course I know about quark-gluon plasma and strange matter don't be silly." But I shouldn't have been so overconfident, I never saw nuclear lasagna coming.
😂 we've all been there.
I'd known about nuclear pasta for a while (including other forms like the gnocchi and bucatini phases), but had never heard of quark-gluon plasma. Interesting how different people wind up with different "holes" in their knowledge base.
You have to appreciate the script writer for consistently ending all scripts of all episodes over almost a decade with the phrase "space time" 👏👏👏👏👌

@@brotheralaric7177 well, black holes can bend space-time so much that even something like light we always considered as instantaneous or at least insanely fast from our tiny weak human perspective, can't escape from it's gravitational force if it's too close from it. Its core is actually so dense that we don't even know how matter could behave in such a place.
Neutrons stars are not on the same level at all.
Those transitions to the ending words of spacetime are so smooth, they're used as a superfluid in particle accelerators.
for what? lubrication? :D
@@aatsiii They're also highly charged with wittiness, so when it becomes a superfluid it also becomes a superconductor. They're used to generate the magnetic fields in the accelerators :)
LONG STORY SHORT... uh we don't know. Take the unsafe shot instead.
HOW AND WHY E=MC2 IS NECESSARILY AND CLEARLY F=MA ON BALANCE, AS ELECTROMAGNETISM/energy is gravity:
Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. C4 is the proof of the fact that E=mc2 IS F=ma ON BALANCE. This explains the fourth dimension. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=MA ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma. ("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity.) The EARTH/ground AND what is THE SUN are CLEARLY (on balance) E=MC2 AS F=ma. TIME dilation ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma IN BALANCE, AS ELECTROMAGNETISM/energy is gravity !!! (Gravity IS ELECTROMAGNETISM/energy.) The sky is blue, AND THE EARTH is ALSO BLUE. The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma ON BALANCE. Great !!! This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! It all CLEARLY makes perfect sense. BALANCE AND completeness go hand in hand.
E=MC2 IS F=ma. The MIDDLE DISTANCE is thus balanced with/as the full distance (in/of space), as the stars AND PLANETS are POINTS in the night sky. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Time DILATION ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. Indeed, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. (The sky is BLUE, AND THE EARTH IS ALSO BLUE; AND the stars AND PLANETS are POINTS in the night sky.) It all CLEARLY does make perfect sense. BALANCE AND completeness go hand in hand.

THE best explanation of neutron stars I've ever heard. Sometimes this stuff goes over my head, but this was spot-on.. Thanks Matt, and all at SpaceTime!
It's interesting seeing polymer-type chains develop.
it was interesting, since in the real world long chain polymers are also created under extreme pressure..

Great info! Just one correction: Jupiter and Saturn revolve around the sun in roughly 12 and 29 Earth years, not 5 and 12. Thanks for this series, PBS television needs to present this type of content more often.
This was fascinating. I've probably forgotten it all already but I love these bite sized pieces of physics. Mind blown AGAIN 😆
Science is epic and i can easily recommend you more, if you like,

That sounds like it could really work as a jumping off point for Lovecraftian satire.
I was seriously inspired as a kid by Robert L. Forward's "Dragon's Egg" series, rigorously postulating how life on a neutron star would exist. I wonder how the science holds up now.
@OMG Puppies Yep. Say Hello to the Cheela on the way down.
I loved that story. Thank you for reminding me of it.
Loved that book, the Stephen Baxter book Flux was also an interesting take on life inside a neutron star.
I love this book, great story
Such a good book. I think for the understanding of Neutron stars at the time it was pretty spot on. Now…. Not so much. For example, the height of the mountains in the book are too big by about an order of 10 IIRC. But a lot of the fundamentals still hold.
It would be interesting to "see" what it would look like if you were hypothetically standing on the surface of a neutron star (obviously impossible due to the intense gravity but still). There would be quite a bit of gravitational lensing, so it'd be really neat to see a render of what it would look like. Not nearly as much as a black hole, but I wonder if you could look in front of you and see the back of your head.
Dr. Robert L. Forward wrote some GOOD science fiction. One novel, I'm sorry the title escapes me, concerned life occurring on the surface of a neutron star.

Thanks to Matt for one of them most detailed descriptions of a neutron star.
Yes! Neutron stars - by far one of my favorite subjects in astronomy/cosmology! Thanks Matt for this episode :)
Great - then I'll ask you: Obviously extreme gravitational forces are a very early player in the cause and effect chain of events. So having said that - Is gravity somewhat responsible for running what amounts to a neutron decay in reverse? Or is it the high pressure as a result of extreme gravity?
Normally (as Matt indicated) that many neutrons on iron or zinc, or anything else wouldn't exist to begin with under normal circumstances and if they did momentarily - they would beta decay away neutrons until nuclei are stable. If extreme gravity is a co-culprit, then what is really happening at the core where the nucleons are feeling gravity equally from all directions and therefore (ironically) not feeling gravity at all. Would the pressure alone be enough to keep them as neutrons? If strong gravity is also required, then we might have beta decay of neutrons at the core resulting in more (comparatively) protons in the center and electrons flying who knows where?
@@chriskennedy2846 Found a video recently that might shed light on exactly this question. I can't attest to its exactness but it makes logical sense for a largely unintuitive topic. ua-cam.com/video/n1FhudqXgvI/v-deo.html
@@chriskennedy2846 the neutrons of neutron stars are formed from either gravitational collapse or inverse β decay ( proton+electron= neutron + electron neutrino)
We dont exactly know what happens in the cores of a NS but some suggest that there may be hyperons - a hadron made from up, down and strange quarks, or some other state of exotic matter.
I'm with you on that, Uzair!

I would argue in the opposite direction on not counting black holes as the strangest things in the universe, on the ground that the event horizon would put them outside the causally connected universe we live in
Gravity is a causal effect though
Black holes are not really objects, and they are the most simple thing to fully describe. Mass and spin. In theory they also have electric charge, but that should be close to zero for all of them. There is literally nothing else to say about a black hole itself.
All the interesting stuff is in the space around it.
@@Yora21 "not really objects"? So why don't you illuminate us on the precise line where mass and matter cease to be an "object"?
As for simple to describe, I'm fairly certain Stephen Hawking would disagree, were he still alive. To be real, we're having a damn hard time describing them in precise scientific terms.
@@voxorox A black hole contains matter and energy somewhere inside it, but that's just the stuff inside the black hole, not the black hole itself.
@@Yora21 Idk, the amount of matter/energy inside still determines the properties of the black hole. I feel like a black hole is an object with an event horizon like stars are objects with magnetic fields and a wide spectrum of radiation...
Great journey to the center of Faszination. Really enjoyed this episode, three cheers for a wonderful presentation. Congrats to Matt 🙌
I love these, you're very good scientist and a very good teacher. That is the highest compliment I can pay you!

Totally agree. The respect I have for individuals and teams who have committed their considerable intellects to understanding the world around us - it's a very noble pursuit and I personally think society has it all wrong when it comes to who to idolise. Not actors, not sportspersons, but people who have given us new understanding, who have contributed to the knowledge for the benefit of all.

@@reidflemingworldstoughestm1394 You should start your own channel... WITH BLACKJACK AND HOOKERS!
Diamondium!
Just wanted to point out that the radiation cones don't actually come out at opposite sides of the neutron star. Anton Petrov did an episode about a study of this thematic. So maybe it's time that graphics about neutron stars need to be adjusted to reflect the new discoveries, just like we did with black holes.
Yeah it is definitely far more complicated than just a simple dipole magnetic field however at this point I don't think we have a large enough sample size to say how common or uncommon the observed magnetic pole configurations that calculations based off of NuSTAR observations indicate. A sample size of two is not all that much better than a sample size of one in terms of developing good statistics.
I knew about this when I read Forward's "Dragon's Egg" in 1980.
I like people who critisize or argue. But I respect people who query a theory / supposition put forward by somebody if they present facts or experimental evidence to back up their argument.
@@markfergerson2145 Hi Mark, "Dragon's Egg" has been on my list of sci-fi books to seek out for a long time. Worth reading, in your view? If nothing else, Dragon's Egg sounds like one of those fantastic thought experiments that also works as a novel in the right hands. Know of any good place to get good (hard) sci-fi novels? I love my local libraries, but they seem to stock what's popular with the citizens and that means relatively little of the sci-fi stuff I'm interested in. (Alastair Reynolds, Arthur C Clarke, Asimov, Iain M Banks, Kim Stanley Robinson, etc)
@@DanielVerberne Forward has been criticized for writing "cardboard characters" with little or no conflict among the human characters, which many feel is unrealistic. That may be off-putting to you. However, there's a LOT of conflict between his alien characters (the inhabitants of the neutron star) and yes, there are a lot of heavy-duty hard scientific concepts (and no shortage of SF speculation) woven into the story. I have Asperger's (or HFA or whatever the Cool Kids call it these days) so character conflict was less important to me than the scientific bits. I enjoyed both Dragon's Egg and its sequel Starquake enormously.

Thank you for doing what you do here. You're an amazing host and your channel along with a couple others changed my life for the better. This one the most though. Since I started watching years ago, I look at the world differently. Sometimes it makes me sad to look around, but other times I am utterly amazed that anything exists at all.
I think you buried the lede here -- you just casually dropped that we've discovered very high temperature superconducting material! I mean yeah we can't use it, but it still counts.
We can use it in our thoughts, and science fiction. That's sort of using it.
I don't think it's really buried. IIRC, there's a lot of high pressure high temperature superconductors. The problem is that we can't find a low pressure high temperature one.
@@hhaavvvvii AFAIK, no high temperature superconductor has ever been created. Carbonaceous sulfur hydride is the highest temperature superconductor yet. It has a transition temperature of 15 °C at a pressure of 2.67 megabars.
Well he did say it was all theoretical at that point. And it's not like we can make some to confirm it.
Yeah theoretical for now….
Question for you: What would neutron star material once it had cooled down look like/behave and what could you make with it?
Considering the material can only exist under the extreme pressures like the ones inside a neutron stars, it'd most likely decompress rapidly, letting off all of its bound energy in the process, making for one huge thermonuclear explosion :D

You know, instead of stressing about The J. I. Neutron, you might have been able to just get a lift from Ms. Frizzle. She does have a pretty rocking ride after all, and well equipped for these journeys.
Impressive stuff
Thanks for sharing your thoughts with all of us 👍😀
Neutron stars are perhaps my favourite space thing just because their properties combine unimaginable properties at a comprehensible scale. Like, I can visualize an object the size of a neutron star.
"The power of bad science-fiction"? Best quotable sentence I've heard in a long time.
Although the majority of people watching this are exactly at that level, the Dunning-Kruger level of thinking they know, when in reality they do not understand anything.

Nah mate. PBS spacetime makes me fascinated and intrigued with the workings of physics in the universe. Kurzgesagt makes me have panic attacks about how much time I have wasted and am still wasting.

What kind of existential crisis they are in
I really want to know if the weak gravitational waves from massive objects are responsible for at least part of the seemingly random fluctuations in quantum systems. The waves pushing those particles around in unpredictable ways and giving the push needed to tunnel small distances at those scales among other things
Short answer: definitely not, for a tonne of reasons.
One reason that I could instantly think of is that if quantum effects are caused by gravitational waves, there would be some assymetry in spatial direction since waves would be stronger coming from certain directions with closer neutron stars. There is no such assymetry in any quantum effect. Also quantum effects would change with respect to time as black hole collisions would temporerily increase the amount of waves present. No such changes in time are present in quantum effects.
You could overcome the above issues if you assume that quantum effects have no or weak dependence of the strength of the waves. While this can't technically be disproven, it seems very unlikely since your motivation is that partlicles "gain energy" to tunnel through barriers, which would surely have some dependence on amplitude. Also the frequency of the waves changes with time and direction which makes things more ugly. Also not all quantum effects are "wave-like" (see quantum entanglement for example) and any theory that attempts to explain quantum mechanics with some sort of "pilot wave" effect encounters huge issues when dealing with modern quantum mechanics, gravitaional wave theorys would be no exception.
So yeh, the slighlty longer answer is while what you said can't technically be disproven, you could just as easily say that quantum mechanics is caused by invisible butterfly fairys or something - ie it's not based on any sound logic.
This is what I always wanted Discovery Channel and later Discovery Science to be while growing up; would've been a perfect warm-up for my bed-time stories read from various astronomy textbooks.
I love your voice and your explanation. It's (usually) easy to understand such hard concepts
For some reason your pfp reminds me of pucci
I was about to go to sleep an hour ago. Then, I noticed Man of Recaps had uploaded a recap for Dexter. So naturally, I watched it. After that, I was sure I'd go to sleep. Then, I noticed Science Clic English had uploaded a video about falling into a black hole. There was no way I could miss that. So I watched it. Finally, just when I was sure I'd definitely go to sleep now, PBS Space Time uploads a video about neutron stars. Am I destined to be sleepless tonight?
Cool worlds lab also did a vdieo on green stars...!
I had Wonderful Person Anton followed by that ScienceClick's falling into a black hole video and now this. What a treat!
Yes, because next one is spaceX translation :)

@@rarewhiteape Roko's Basilisk is just Pascal's wager with extra steps. Both of which are illogical. So don't worry, I'll be sleeping just fine 😁
Just how much is the flow of time altered by the extreme mass of a neutron star? As I recall, the denser an object that distorts space time, the slower time flows relative to an outside observer.
That is true but it really only has a noticeable effect at the singularity
This channel should be required viewing in schools for science class
"Nuclear pasta is the strongest stuff in the universe."
"Could it even hold itself together, you know, anywhere outside a neutron star?"
"Well..."
It will probably be unfeasible for us to use simply because the pressure isn't enough basically anywhere else for the spaghetti to hold, still interesting though

I love Neutron Stars. I remember reading the weird science series and one of the claims always struck with me. If you dropped a marshmellow from orbit it would land with the force of a nuke. Also as a creative writer I have a series I would like to one day publish that blurs the lines of science and magic. One of the climatic fights involves an important character beating an antogonist via harnessing the power of a binary neutron star system at the moment the two stars merge and then desync. All that power delivered to a jawline. KO!
Looks like I will have to update that section with descriptions of the bending of nuclear spaghettit tubes, the undulations of the nuclear lasagna, the crashing of ten cm tall mountains and how bosons bored through the antangonists brain as their jawline briefly becomes degenrate under the pressure. Previously I just really described it in terms of a cosmic ballerina dance where two partners become one all the way down to the quantum level before seperating the embrace. That's the moment the punch lands. As the two stars disentangle and revert to their relatively speaking stable orbit around one another.
Kinda sounds like Dragon Ball. What is the story about? Omnipotent entities who exist in higher dimensions that can manipulate the forces of the universe?
Because I am writing about that too😂
Wow. Your videos are all great. But this one. This one is simply beyond amazing. Better than any of my undergad astrophysics lectures. Thanks! I feel smarter now.
Thanks for getting us out of there just in time. I was beginning to get anxious.
1:38: Carl Sagon's or Nel Degras Tyson's (spelling?) "Ship of the Imagination" was not out on lone. Figured. It would be like Tony Stark trying to get Batman's Batmobile.
Does anyone know if PBS SpaceTime has covered fuzzballs? I just learned about them about two weeks ago and would love to see Matt's take
Searching for PBS spacetime fuzzballs has no results. I don't think they have made a video for it yet.
Fuzzballs are theoretical tho
They should cover SpaceBalls. The most accurate physics movie in the universe.
@@skyricq mhm I did the same and so wanted to ask just in case it was hidden within a random video. thanksssss
@@eduardoGentile720 true, but it's not uncommon for spacetime to cover subjects like strange matter, pre big-bang speculation, string theory, Alcubierre drives, etc., etc.
It’s great that you point out right up top that black holes don’t count as objects
If you were able to scoop the surface matter off the star, it would slowly expand as you moved it further from the core.
Had weird déjà vu then I remembered Kurzgesagt has a video titled "Neutron Stars - The Most Extreme Things that are not Black Holes"
Loved the episode, like usual :)
Can you please make a video about Electron Capture? That seems very interesting.
Loved it. Thanks.
THANK YOU PBS SPACETIME!!!!
PBS space time: we’re going to explore states of matter in ways you’ve probably never heard of.
Kurtzgezart in a nutshell: hold my neutronium
Right! I had to do a triple-take looking at this title in my feed, and thinking, "...and this *isn't* Kurtzgesagt?"
Don't trust a Europocentric neutronium -plutonium equaliance theory, anyway.
Makes me wonder if, when a NS gains sufficient mass and becomes a BH, if the quark plasma becomes structured, sort of repeating, in its own ways, the changes as a function of depth in the NS.
These videos are excellent and I'm so glad they exist. That being said, I wish they could slow them down and take more time explaining each element before moving on the next.
well its tough because he has to write a video that will preform well on his channel, not too long and interesting, but you know he could have talked about this one subject for hours
I just hit the pause and absorb it before the next amazing bit.
This is another great video - entertaining and informative. I do wonder though - you talk about the neutron star makeup in terms of physical matter, but I wonder how it would be defined in terms of the “other side of the same coin” in terms of it all being a bumble of energy waves??
PBS will be the first one building a base mars, no doubt ✌🏻
Its fine i am sure he just had a bad day ☺️ ✌🏻
Don't call yourself a foodie if you've never eaten nuclear pasta
A bit heavy for my taste, but I’ll admit it absorbs the sauce like no other.
Thank you for the video.
Mind blowing stuff!🌌☄
I can fall asleep to this voice with a massive party raging around me
Can you plz do audio books?
I actually do replay older episodes of PBS Spacetime whenever insomnia hits! XD
I'm fascinated by the subject but I just can't focus with that voice going on. New host please!
@@roseannelajara8659 Oh, I'm not the only one.
Right? I often fall asleep listening to these at night (when I'm trying to pay attention) and have to watch them again the next day!
Ooh, a pasta-themed episode. Time to watch with immense interest!
R'amen.
Nice explanations👍
Wonderful video!
Yess.. Neutrons and stars made of them are one of the most mysterious phenomena we know of. One of my favorite subjects. It really implies that everything is made of exactly the same "stuff" but why does it want to differentiate into its different "spins", charges and other properties in the absence of enormous gravitational fields? Looking forward to the LIGO teams' findings or lack thereof.
Nuclear Pasta, Nuclear Lasagna? It’s clear that these Scientists were quite hungry and forgot to eat while exploring this topic….
actually, i have heard of all these states before...
...but i've forgotten most of them since last year so that's why i'm re-watching the video! :)
Thanks for going where too many scientists I've heard refuse to venture, piloting the indestructible spaceship of imagination, powered by fusing curiosity with scientific hypotheses , to help us visualise the possible reality of these amazing objects. Imagining how it might appear through our senses helps bring theory to life, for me. Good work.
So, could a neutron star be disrupted? I'm thinking an extremely near miss with a black hole, or maybe ground zero at a super nova. What would happen with all those particles as pressure was released?
+1 I want to know too
This very channel has done a video on our first detected neutron star merger, an event that disrupted both stars in a flash of photons and heavy elements:
ua-cam.com/video/MmgMboWunkI/v-deo.html
ua-cam.com/video/kL81uuYW9BY/v-deo.html
It's relatively easy to calculate what would happen to a gram of neutrons when they are not prevented from decaying by the huge pressure inside the neutron star. (You need to know the number of neutrons in one gram of them, energy of decay of one neutron, and what percentage of neutrons decays each second).
The end result is: one gram of neutrons gives off 66 gigawatts of power as it decays.
Now, a disrupted neutron star is approximately 10^33 grams of neutrons. The power output of that many neutrons decaying would be about 6.6*10^40 watts, very approximately.
hyper nova maybe?
Neutron stars are literally formed during supernovas, and I'm not sure it's actually possible to break one up beyond ejecting some surface material. It's much more likely that you'd get a merger and the resulting object would collapse into a black hole.
