- Step into the enigmatic realm of neutron stars, where the universe showcases its extremes. This documentary-style video guides you through the life and legacy of neutron stars, the dense remnants left by supernovae, the explosive deaths of massive stars. We delve into the heart of these cosmic enigmas, exploring how they compress more mass than the sun into a sphere just kilometers across, resulting in densities and gravitational fields almost beyond comprehension. Discover the peculiarities of neutron star phenomena, such as pulsars that beam radio waves across the cosmos and magnetars with magnetic fields trillion times stronger than Earth's.
"...the crucible the universe uses to forge its most precious elements."
What a beautiful analogy.
I have a lockbox containing my gold, silver and platinum. I decided to name it "Neutron Star Collision Byproducts" haha.
@@SubvertTheState Yes! Do it! Now, to get your hands on some Neutronium and Stange Matter...
Idk Id be pissed if I was a blacksmith and my forge exploded with such ferosity that it destroys the solar system and creates heavy elements

You had me at "Neutron Star"
For as far back as I can remember I have always had a fascination with Neutron Stars. Great presentation. Thanks
Same here!
Awesome video. Pulsars have always taken a big chunk of my daydreaming time. I love this channel, you deserve so may more subs!
Magnetars have taken up a lot of mine haha
Bravo
Your work is much appreciated by this layman
i too am in bed 👍
I appreciate his work too, even though I happen to be standing up👍
Well done and in words/explanations I can understand!
Magnetars are the real bad boys
I agree!
Yes, the density of the matter is high but has anyone thought about the density of the magnetic field? At 10^14 Gauss a teaspoon of the magnetic field has an energy comparable to all the electricity used on earth for two years. If we use Einsteins formula for calculating that to mass it will be about 2000 kg.
@@teamsafa that's extremely confusing. My brain can convert mass to energy reasonably but not magnetic field to mass haha
@@SubvertTheStateA magnetic field contains energy. This energy is equivalent to mass according to E=m*c²
@@teamsafais it the formula used for speed of light?
Its a good thing there's lots of room in outer space.
They are endlessly fascinating, and in their own way, beautiful.
Great video! I like how you used sound with your graphics; I haven't seen many creators make clips as immersive as yours.
But I do think that the quick animations would benefit from a 60 fps upload. What you presented definitely gets the point across, but at 30 fps many animations felt jagged to me. Just some observations, I hope the feedback helps!
I think it would take a whole team of CGI creation specialists to produce such an animation. Some of the animations from the video were produced by NASA over months and even years after the whole complex of pre-simulation process.
@@maxstrelets263 Why couldn't you just upscale it?
@@RT-qd8yl Weren't you talking about frame rate, rather than resolution?
Check out History of the Universe if you like these sorts of videos. Also Cool Worlds.
@RT-qd8yl What @maxstrelets263 said, it technically wouldn't be upscaling. Some AI could probably interpolate the other frames, but that sounds expensive.
Most modern graphic libraries should provide things like this in 60 fps though, even if it requires a more expensive license. My point was mainly that 60 fps graphics are much more digestible for people who don't understand the topic already. It feels way more coherent at those higher speeds
I’m a medical doctor and I still find myself nerding-out to cosmology videos. I guess that little child inside all of us remains well into adulthood
I enjoy the Fascinating content and informative velocity.
Great show - Thanks -Fx at about 8 minutes is very bright and flashing
Really digging your videos. They are produced very well and you communicate science very well. What is your background?

Much appreciated video. Learned a lot, Thank you.
Interesting factoid about neutron stars: The *_speed of sound_* inside a neutron star is approximately equal to c / (3^.5) - that is, the speed of light divided by the square root of 3.
The writing on this channel keeps getting better imo. Not sure where he gets his ideas from but I’m loving it. This has got to be one of the top sci-fi channels on RUclips. I love the concept of a “neutron star.” I’d love to see the idea fleshed out in future episodes. The only issue I have is I think he went a little overboard with the density. 1 billion tons in a teaspoon sounds cool but it takes away from what is otherwise a very realistic idea. I think it should be toned down just a bit, maybe 10 tons for a teaspoon would be more believable. I’m pretty sure anything as dense as what is described would collapse into a black hole.
Please pardon me as I merely wish to be informative and not to offend, but this is a science video about actual things. Neutron stars are real. They were predicted long ago based on Einstein's equation and have since been observed. The weight of a billion tons for a sugar cube sized amount of material is based on neutrons without electrons nor empty space as atoms are. I truly hope that what I said here has been helpful. I wish all the best for you and those you love.
I’ve been watching videos like this for years. The creator did a great job in this video, but none of this info is new and hasn’t been covered before. Search “neutron star” and you’ll find plenty more just like this, along with the scientific calculations of the teaspoonful weighing a mountain. That’s a hard idea to wrap our puny human brains around, but that doesn’t make it false
@@gregg9725yeah I agree. There are a some inaccuracies thrown in here as well, but I understand that he’s probably also trying to keep it limited to a depth no further than the general audience he receives.
It's a science channel not a sci-fi channel.
Geat video ❤ Thank you 😊
Great documentary thank you
Just as crazy is that all of this energy reacting in these humongous explosions and it wouldn’t make any sound
Is that true?
@@halfstep44 Absolutely! Sound waves can’t travel thru a vacuum, hence there would be no sound
A very nice overview.
Thanks for this. Was always interested in neutron stars very cool
Fantastic Video I learned and Enjoyed very much. 👏 bravo
really great visuals!
Nice to see Joel Osteen narrating space facts. Love the Southern drawl! 😁
Brilliant and clear explanations.
Our gold here on Earth came from two colliding neutron stars.
I'm just burning doin' the neutron dance.
I love this video! Beautiful graphics! And the narrator went into much greater detail than I've heard in other videos.
Wonder how many people think about neutron stars 😊
It seems like many more than I realized
I do. 👍
I think they are awesome. Always been in awe that a small tiny bit weighs billions of tons.
Like 5
I meant. If you go outside and ask people in the street what they think about neutron stars or thermal nuclear fusion, not really a subject for a short 😊
Fantastic, informative video.
Bringing that into earths atmosphere would be catastrophic
Would prefer more compacted content instead of repeating information two to four times.
Neutron stars are the craziest objects in the universe to me. They are more bizarre and interesting than black holes even. Probably because they are researched (seemingly) and talked about a lot less.
Magnetars are where it's at though. If a magnetar were where the moon is, you would barely be able to make out the dot blazing such bright light, but would wipe every credit card on the planet. Closer would polarize all of the atoms in your body which is what am FMRI does. Closer still would break most chemical bonds which keep you alive.
If you want something even more bizarre... the larger the black hole, the LESS DENSE the material that makes the black hole.
So Stellar black holes are like neutron stars, Sag A, its density is pretty high but reasonable, and a supermassive, would only be as dense as water.
So much wrong with black hole science. That makes them less interesting
@@m4rvinmartianWe dont know the actual size, only the size of the event horizon. Lots of the science on black holes is very sketchy.
Neutron stars… 100,000,000,000 tons in a spoonful… That’s not how chemistry works. It’s lunacy for a much better alternative. If you’re interested check out the electric universe.
Gee. That's bizarre.
It's fun to think about neutron star as really a giant atom with a collosal nucleus. Would such a thing have a 'chemistry' defined by an electron cloud?
What’s holding up the teaspoon?
Galactus
There's no spoon
caseoh
A very long lever
Thor is holding it
Great video. Please avoid descriptions like 'a teaspoon of its material weighs as much as a mountain'. We have units.
Lets stick to American units, like elephants, footballfields and olympic swimminpools.
Realy I like this video so so much its interestyng
Actually, Pulsars are more accurate/consistent/reliable as a time measurement device than atomic clocks / atomic decay.
I love watching space matters it's interesting and then narrator makes it interesting
This explains why my chihuahua goes crazy once in a while.
Being this dense, what would these stars consist of. What is the heaviest element that we know of and how can it be compressed to such extreme density?
"nobody really knows"
-Universe
The habitable planets are just part of the cosmetics of the universe. Maybe Neutron, Magnetar, Black Holes plus similar, are the ones giving galaxies and the universe it's shape and distribution.
Does this teaspoon make me look fat?
uhthAts prEtty fUnny ty for that
if only humanity could utilize the ultra dense ultra strong material of neutron stars
When I watch stuff like this I just think like damn we are just grains of sand in the grand scheme of things so complex
If no more nuclear reactions in neutron stars (or maybe i misunderstood) how does it still 'shine' ?
No new information here. Showing of the size comparision is full inacurate. Besides that, it's a nice work.
Can you be more specific, please?
your spelling by comparison is inaccurate
Imagine if we could mine or harness the energy from a neutron star ⭐️
I never thought a Neutron Star was bizarre. I just think that about you quirky scientist
Even cold November rain. 2:06
Wonder how they came up with 1 spoonful of starmatter weighs 1 billion tons.
Density if the matter was brought to EARTH.
The equations are actually not difficult to perform. It’s the relative density of degenerative matter packed into the defined space, that amount of mass is calculated to determine the weight on earth under standard gravity at the surface.
But, a teaspoon of a neutron star would almost instantaneously expand. Either way, it would be deadly.
I read Steven Hawking's books with great care but that was a long time ago and they were certainly Best Sellers.
It was great to vibrate in that way.
Mmmm
who's holding the spoon up?
Cool scene 15:26
It’s a bit of a catch 22 with stuff as dense as that. It couldn’t exist in our environment. To weigh it you’d need scales made of the same stuff in the same environment so it would just be normal in that context. I need a joint that took a lot of effort to spit that out.
Why/how does something made of neutrons support a magnetic field?
That's something that I have wondered about, how can something made up of particles with no electric charge generate a magnetic field.
6:14 If we could figure out a way to study the inner working of a neutron star, we just might be able to figure out what a black hole singularity is made of?
From what I am understanding here is that the time dilation between the particles in the neutron star and relatively empty space causes the gravity from the the difference in time trying to equalize itself. This may also happen on the atom scale but at barely noticeable gravity effect to us feeble humans. I really think gravity has something to do with non equal passage of time.
Speaking in real - you are highlighting a fascinating aspect of Einstein's general relativity, where gravity, influenced by mass warping spacetime, affects the passage of time. This phenomenon, known as gravitational time dilation, is most noticeable near massive objects like neutron stars. It does imply that at the atomic scale, or in regions with less significant gravitational fields, time dilation effects would be much subtler and harder to observe directly.
If an intelligent being with the ability to manipulate gravity fields came to earth, they could theoretically live entire lifetimes within 30 milliseconds. Humans can’t perceive time in lesser segments than this. So, beings could theoretically live on earth without us even knowing
You think that because you are correct.
What about black holes or quark stars? I know the density of supermassive black holes is potentially low if you include the entire volume contained within the event horizon but at the singularity the density is effectively infinite...
For anyone wondering what happens after two neutron stars collide a black hole is born
That's wrong not posible
I can think pretty bizarrely.
This guy sounds like a highschool principal in South Carolina.
At 6:41 you mentioned strange matter as consisting of equal numbers of top and bottom quarks, as well as strange quarks. What you meant to say was up and down quarks, not top and bottom quarks, which are flavors of third generation quarks which do not have an approximate isospin symmetry like the up and down quarks.
It seems like they use too many crude AI videos, to the point where I wonder if the script is also made by AI.
Why does a neutron star have a magnetic field? Shouldn't it be electronically and magnetically neutral?
If we reason reason sensibly, neutron stars have magnetic fields due to electric currents from charged particles inside them, similar to electromagnets. Although they are filled with neutrons, the presence of protons and electrons contributes to these magnetic fields. The enormous strength of these fields is still a subject of research, and theories such as "flux freezing" offer a partial explanation.
There is some sort of friction that's rubbing the electrons off the neutron causing magnetism. Maybe it's super fast rotation is rubbing against the fabric of space/time?
Interesting question!
They have nuetrons at the core, that's called neuclear sheets/pasta. Next layer is of protons followes by a cloud of electrons. Outter layers don't have enough pressure to crash electrons into protons creating neutrons. Hence the massive magnetic field.
Could a neutron star or a pulser be a faild black hole or maybe a black hole losing its density? Kinda like people aging. Sounds like the process is similar but with more density.
I'll take one nuetron star, a cup of dark matter, one cup dark energy, one super massive black hole, add in some gravity waves, the c.m.b ,mix in some warped space- time and, lest we forget,a big bang and cosmic inflation. This horse manure passes for real thermo dynamics in astrophysics. Ain't it nice? Sorry if I've offended the anyone.
No intelligent people are offended, we are mostly amused by simplemindedness.
Ok then in my simple minded way I thank you and refer you to a great scientist Dr.Pierre Marie Robitaille. Nuff said.
Psht, what kind of half-baked recipe is this?
Any true cosmic chef will add a pinch of strange matter and leave it all sauteéd in a high dose of gamma radiation for no more (but certainly not less) than 15 minutes.
Bon appetit!
how about a sprinkling of God's will? :D
Nature works in a simple easy way. These theories represent the death of astrophysics.
*Let the Sunshine In...*
I think its ironic that people complain about God being intrusive and keeping records of everything you do or think yet we now have cameras everywhere and everything is stored on the "cloud" and have dei scores.
@6:08. I've heard of antipasta but not antignocchi. Probably not the best dish for those watching their weight.
love it
Neutron stars aren't as heavy as Dimebag Darrell's breakdown on 'Domination' tho.
I have a question, is it the material of the star that actually weighs that much, or is it the gravitational pull of the star itself. That makes it weigh that much?
The first one. It is incredibly dense matter that generates that much gravity.
There’s a movie about a neutron star coming into the solar system and ripping the atmosphere off the earth before breaking it apart.
I believe you’re referring to the documentary “Evacuate Earth”. It’s a great watch that’s for sure
Depending how close it comes, if the Tidal forces disrupts Earth enough, Earth will explode like Mentos in Pepsi.
The whole Iron Core, whether liquid or solid, is at 12,000*F and the boiling point of Iron is 5,200*F. Change gravity or pressure enough and we blow up.
There must be good planets around some neutron stars is just like a sun maybe the planets shall be lighting
Humans may eventually understand all of the physics of the Universe, but we will never know WHY?
I assume there is no why, I don't think the universe has a purpose/intention, it just is.
@@flavadave86 Yes, but why?
i cannot contemplate the size of space, why are we here? defo not to wage war amongst one another. so confused.
We are here to know thyself. An eye inward
We r here just to pass few insignificant years in terms of cosmic scale and then disappear but look @ the ego factors of 99% humanity.... It never dies
We are here to argue the points of view we have using our personal first hand accounts of life and utilizing the accumulated experience we acquire through the extent of our conscious state here in this human body, whatever this is…..Sadly the difference between our points of view causes pain and suffering too often.
Maybe we’re here to wage peace amongst one another.
Despite our technical advances over the last few decades, the human race is still controlled by Neanderthals.
Normally we can’t see atomic nuclei, but we do when we look at Neutron stars. You’re seeing one big neutron. It’s literally nothing but neutrons and maybe a black hole and radiation but you get the picture
1 teaspoon full weighs a billion tonnes?hard to get your head around that for sure!
A teaspoon of a neutron star would be a huge explosion without the rest of the mass pushing it together. Would probably destroy the Earth.
I have always heard that you learn the secrets of the universe when you die. I sure hope so!!!❤❤❤
Can pulsars speed up or slow down?
Question is; how did they get a spoon that big?
Their magnetic field is the most f'd up aspect, but they're almost never mentioned in videos introducing neutron stars to people. Magnetars are just batshit crazy, but that's just very young neutron stars. At any rate, long story short, the magnetic fields of neutron stars, and magnetars in particular, is so strong it makes chemistry impossible in a pretty long range. If the sun was a neutron star, then the magnetic field would extend past Mercury before quickly declining. Atoms would no longer arrange their neutrons in clouds, but in columns, disabling all known chemistry from functioning. It's so powerful, it causes spacetime itself to crystallize, which is bonkers, but too complicated to explain here.
I just came here to say ofc it’s a 100 billion tons, look at the size of that spoon!
But we cannot say a black hole is denser than a neutron star because we don't know what space matter is occupying inside the black hole. Is that correct?
They’re talking ab my left ball
There's plenty of space out there
Black holes get too much attention sometimes. I love Neutron Stars! Their magnetic energy potential is phenomenal--and to think some of them have planets in orbit!!! Whoa! Any "life" that may develop on a planet that encircles a Neutron star must be extremophiles!
Yea that is interesting. Scientists just took some cancers into space to see if any responses to negative gravity. Any life found in the vicinity of a neutron star might have irregularities.
Can anyone confirm whether or not the following ideas about neutron stars are true? These have fascinated me for years.
1) To an imaginary observer on the surface, the only sky visible would be confined to a hole overhead -- an illusion due to the intense gravity bending light from over the star's horizon, making it appear that the observer was at the bottom of narrow bowl. In other words, only light coming straight in from above could make it to the observer, and the horizon would appear to almost close up overhead.
2) If you were to somehow materialize on the surface, your atoms would almost instantaneously be spread out over a large area, disassociate in a flash, and become part of the star.
Thanks!
Okay... But how is it that these massive distant bodies come to find eachother and collide in the vastness of the observed universe?
Theres a lot of space...
And yet they seem drawn to eachother from distances which seem impossible.
What happens to the stuff in the space between them?
Is there loads of planetary debris orbiting these massive neutron stars?
Man, neutron stars collide when they're in binary systems or close enough to attract each other gravitationally, eventually spiraling in due to energy loss from emitting gravitational waves. The vast space between them might contain some matter, but as they near, their intense gravity dominates, possibly capturing or disrupting nearby debris. This process is slow on human timescales but inevitable over cosmic time.
You assume thing in space do not move?
Apparently, around 98% of the gold on Earth originates from the matter that's created during the relatively rare occurance of two neutron stars colliding with each other.
Gold and all elements heavier than iron are created during a supernova. After the supernova there will remain a neitron star or a black hole depending on the mass of the star, heavier stars become black holes. If two neutron stars collide it probably creates a black hole.
@@garrett6064 You need to recheck your sources and consider changing your "all elements heavier [you meant more massive] than iron are created during a supernova". As powerful as the great majority of supernovas are and though it's absolutely true that the origin of almost all the elements more massive than iron are made as a result, MOST aren't powerful enough to create gold and some other, rare, heavy elements (like uranium, etc.).
@lazurm love how you use the same non-technical jargon "heavier" two sentences after trying to correct mine. 🤣
@lazurm but on another note, you are correct that neutron star collision does initiate the r-process and my info is out of date.
Some form of life that we cant perceive is purposefully doing all this. I wonder why
Would a teaspoon of neutron matter expand into the size of a mountain when braught to earth with a much weaker gravity to keep that matter compressed?
Great question! I hadn't thought about that!
You bet! Very good.
I'm sure it would expand, but don't know what atoms that would form, maybe it could be hydrogen.
You mean… Explode?
Oh jeez, maybe that's not such a good idea...
