I've known about neutron stars for a long time, but it never occurred to me that we could see their back sides from the front. Every one of your videos that I've seen offers some gems of new concepts. Keep up the brilliant work!
That's what I love about this channel so much. Videos about topics I've been familiar with for years always offer something new or unexpected to learn.
Dude I loved this video. It's getting hard to find videos that teach me something new about astrophysics that I didn't know before, but this one definitely did it. I know about neutron stars and a lot of the info you provide, but you provide some extra stuff that I never knew before. Neutron stars can't create magnetic fields if they are only neutrons. Makes sense.
Hi I love your videos, I recently Subbed around a week ago. I love watching maths and science videos in my "free" time, and when I say "free" I really mean when I should be doing work.
I've been watching RUclips videos for almost a decade now, and this is probably my 2nd comment ever here. I follow all the top Science channels and trust me, yours is the best. Channels like PBS Space Time and Minute Physics can sometimes be a bit too complex and other channels can be too simple, but the balance in yours is spot on. I also love the humor. Just like everyone here, I'm perplexed at the amount of subscribers you've got. You deserve millions of subscribers for the effort you put into! You truly are awesome! I wish I could start earning soon so I can help support you. Please don't stop these videos. Have I mentioned they're lovely, yet? :)
This video was gooood. Got the impression you talked a little slower than usual, which was relaxing when pacing along. Some of this stuff is neutron-hard to digest
Excellent video! I discovered your channel pretty recently. I've watched several other RUclips videos on neutron stars, but this one had several facts that none of the others mentioned. And I enjoyed the way you presented things. Keep up the great work!
Dude, I just learned you have a Patreon account! You should let more people know. Your stuff is excellent and worth supporting (I just pledged my support).
Not being pushy is a good thing - but you really should at least mention it once in a while, OR reference it 'above the fold' in your description... Otherwise people like me never see it (*my mistake, I know).
1) What are starquakes on a neutron star? 2) What is a magnetar? 3) How a neutron star's life would end over the time? 4) How bright neutron stars can be? 5) Can quark stars exist? Awesome video nick, Nice editing, love your channel.
3) Neutron stars are already dead. They cool extremely slowly due to their high density and low surface area per unit mass. Neutron stars can gain mass by sucking up living stars or white dwarfs. Neutron stars can collide with each other. Neutron stars can shed mass if they get too close to a black hole. A neutron star isn't massive enough to become a black hole (except through stellar cannibalism).
A quarkstar is a different theory of what a neutron star is, where the neutrons break down into a sea of their component quarks. For a perfect video about it, watch Kurzgesagt's "Strange stars - in a nutshell"
This channel is genius! Keep at this, this channel deserves more attention! The information you provide is a more than a match for some big science youtubers!
love the ,,goofy,, style of presenting , it really helps with the ,,Dumbing down,, of the physics cos it makes the viewer feel that the ,,dumbing down,, wasnt needed for themselves, so you made me feel intelligent till the o so soon end. keep up the good vids. rAyZoR.
I wouldn't call a Neutron Dwarf (ND) a 'star', because it's a CORPS of the star! Just like a WD. But thanks to this video I finally realize of how 'r-process' works -- 3:30. When 2 ND collides -- their crust opens and the inner neutronium immediately decays into lanthenides & other super heavy elements. Thanks, dude!
Gee Whiz. These are the best videos. You don't talk down to viewers and you give just enough information to make the subject interesting but no so much that watchers drown in data. Also these five minute blips take a lot of editing, so how do you do it?
Woahhhh epilepsy warning!! - FAST FAST!! I don’t get it.... your production quality is incredible, your methods of getting things out of your brain and into ours are spectacular, your content is on point and extremely educational.... you literally follow the RUclips playbook to the letter, why don’t you have more subs!? I’ve just binged most of your videos and loved ever single one, thanks for putting your time into this, I know it’s not easy!
ur the man thanks for the critic, these other guys say that it would weigh equally to a mountain, this analogy makes more sense that the gravity wouldn't be same on earth.
Ah this solved part of the question I had on your video on Black Holes where I asked how dense matter could get and you asked me to clarify, in which I responded: "what's the smallest particle in which you couldn't collapse anymore?" So neutrons would be the atomic particle that would hold out the longest. Hmmm...
Have you ever payed close attention to the lyrics of the song "The Final Countdown" by the Swedish band Europe? You can be pretty sure, that the writer of the lyrics didn't know anything about neutron stars. Or space in general. Another great video, Nick. Keep 'em coming. Greetings from Denmark.
Another amazing and awesome video! Thank you! A quick question: Since the universe is expanding, would a neutron star, or any other celestial body for that matter, eventually be ripped apart due to the action of space, thus counteracting the intense gravity that is responsible for its very existence? Thank you.
Even if objects got ripped apart from the expansion of space, that mass is still part of the universe. The gravity is still there whether or not the mass is collected in clumps like neutron stars.
a few months ago was "playing" space engine. a space simulation, hence the name. i happend to find a very bright but tiny star in that when i got closer it saw that it warped the space around it just like black holes but warp looked weaker compared the black holes in the simulation and it also had an acretion disk which looked insanely cool! imagine a bright white ball that is warping light and has an acretion disk and is rotating at insane speeds. even when i put the time speed to real time spin was way too fast! i even tried to put a spaceship a few thousand kms away it sucked the space ship so fast that you could barely see whats going on! space is amazing man just amazing. also nick if you are reading this could you please make a video about quark stars and strange stars? pbs space time did it but his videos are for adavnced nerds. im just a noob at this :( and your channel is the only one that simplifying in a way that non-science major people can actually understand it!
I can't put my finger on it... but I feel like the music editing for this episode was different. It's not better or worse... just different. Anyways... great video as always.
One interesting thing about neutron stars is that they can be squeezed more also because the wavelength of the neutron is shorter than the wavelength of the electron - the neutron, being more massive, and thus having more energy, has a shorter wavelength, since E=hf (higher frequency = shorter wavelength). That's one of the reasons why you can press them closer to each other without overlapping and violating the Pauli exclusion principle.
Good video! Near the end you mention that neutron stars look weird up close. I've often imagined that from its surface, the 'horizon' would look weirdly high, i.e. the 'sky' would be less than 2 pi steradians. Is this just due to the gravitational warping of spacetime, or would part of the neutron star's mass also "feel" above you? If the latter, would the gravity felt on the surface be less, since part of the neutron star appears above you? I've also wondered this about black holes where the 'sky' should appear as a tiny circle when looking from just above its surface.
It seems like every other scientist ignores key facts, exaggerates, or lies to us thru omission. Thanks you Science Asylum! I need my science dumbed down but I'm willing to hear the truth!
Will the normal reaction forces and frictional forces (that basically are electromagnetic forces) be present on a neutron star if it were completely made out of neutral neutrons? Great video nick, just love it......
The center of the neutron star is pretty much just neutrons. There's still a little electromagnetism because the quarks that make up the neutrons are still charged, but the main driving force there is strong nuclear force.
I mean that, of the 4 fundamental forces (gravity, EM, strong, weak), the strong force mostly controls what happens in the center of the neutron star ...just like how it does in an atomic nucleus.
Can you guys please make a video of similarities & difference between pulsars and magnetars. They are both neutron stars but how they came to be classified as either one has intriguied me forever.
Slight error, Nick! At around 0:50 there's a diagram of the interior of a star. That diagram works well for the Sun, but for the kind of massive stars you're talking about that go supernova and form neutron stars, the radiation and convection zones would be the other way round!
You are correct there, but I think I can get away with it because (during that animation) I'm not specifically talking about neutron stars... just stars in general. The fluid dynamics inside stars is complicated and the significant differences don't occur at the same "mass markers" as the stellar corpses. Red dwarfs don't even have a radiation zone... like, at all. Not all stars that make neutron stars look the same in their layers either. At some point, you just have to chose one for the sake of the visual. The layers themselves were not the main focus anyway.
There's a Star Trek (orginal series) episode called "The Doomsday Machine" in which the Enterprise battles with a robotic planet killer whose hull was made of solid neutronium (Spock points that out to someone to illustrate the futility of attacking it directly). Well, it turns out that all the Enterprise would need to have done was wait. The neutronium would decay and the planet killer would disappear into a cloud of electrons, protons and various amounts of radiation.
Thanks for the videos :) (just found your stuff recently) I had a question if you or anyone else might know: In the future, if technology were to advance enough, would we be able to harness energy from Pulsar's in the form of a Neutronium generator? Or maybe use equipment to interact with the magnetic field of neutron stars to generate energy?
Are you hoping for things like PewDieSci or SciPaul? That might have been possible if RUclips thought otherwise. Minute Physics used to get >million view once. Now a days barely any science/engineering video get that much view.
I read through all the comments to make sure I wasn't asking a question that had already been asked and answered (Pauli Exclusion Principle for comments???) You mentioned how if you scooped a teaspoon of neutronium from a neutron star that you would die from decay radiation as the neutrons reverted back to protons and electrons. Aren't neutrons stable? How can a neutron star neutron be different from a vanilla neutron. I can grok that a small amount of neutronium might explosively expand because gravity isn't strong enough to maintain the density for a teaspoon amount. But it isn't clear to me why the neutrons in the physically exploding teaspoon of neutronium would revert to protons and electrons. Again, thank you for the time and energy you are devoting to this site, so much energy that you are warping space-time.
Neutrons are only stable inside a nucleus. _Free_ neutrons are _not_ stable (at least the way a free proton is stable). Free neutrons tend to only last a few minutes.
“But what if we scooped it up and brought it to Earth?” “It would explode.”. Brilliant! 😂😂😂
I've known about neutron stars for a long time, but it never occurred to me that we could see their back sides from the front. Every one of your videos that I've seen offers some gems of new concepts. Keep up the brilliant work!

This channel is one of my best discoveries of 2017. High-five to you!
Fantastic job on the animations in this one Nick. Well done!
Thanks! This was the first time I used Adobe After Effects, so it was huge improvement from the video before it.
Superb channel. You've got the mix between silly and informative absolutely spot on for maintaining our attention. Great job, please make more!
This video was gooood. Got the impression you talked a little slower than usual, which was relaxing when pacing along. Some of this stuff is neutron-hard to digest
"You dead" hahahahaha
cracked me up too.
HAHAHAHAHAHA - that was hilarious
Also still chuckling at this.
Outstanding videos.
You need more subscribers. I'm glad to be one of the crazies now. I'll tell all my crazy friends so they'll join too.
Excellent video! I discovered your channel pretty recently. I've watched several other RUclips videos on neutron stars, but this one had several facts that none of the others mentioned. And I enjoyed the way you presented things. Keep up the great work!
These videos are so well produced! You deserve a lot more recognition.
That's it! I'm now hooked to your channel! I won't be able to sleep before having watched every single video :D
Dude, I just learned you have a Patreon account! You should let more people know. Your stuff is excellent and worth supporting (I just pledged my support).

The best video on neutron stars. Glad I subscribed to this channel
1) What are starquakes on a neutron star?
2) What is a magnetar?
3) How a neutron star's life would end over the time?
4) How bright neutron stars can be?
5) Can quark stars exist?
Awesome video nick,
Nice editing, love your channel.
Magnetars are just neutron star with extremly strong magnetic field
Magnetar is a neutron star which has many electrons and so a very strong magnetic field
neutron stars colaps after a long time and become black holes (If I remember right)
3) Neutron stars are already dead. They cool extremely slowly due to their high density and low surface area per unit mass. Neutron stars can gain mass by sucking up living stars or white dwarfs. Neutron stars can collide with each other. Neutron stars can shed mass if they get too close to a black hole. A neutron star isn't massive enough to become a black hole (except through stellar cannibalism).
A quarkstar is a different theory of what a neutron star is, where the neutrons break down into a sea of their component quarks. For a perfect video about it, watch Kurzgesagt's "Strange stars - in a nutshell"
0:16 is the reason I subscribed to this channel

Side note: A video on string theory would be great!
love the ,,goofy,, style of presenting , it really helps with the ,,Dumbing down,, of the physics cos it makes the viewer feel that the ,,dumbing down,, wasnt needed for themselves, so you made me feel intelligent till the o so soon end. keep up the good vids. rAyZoR.
This is the best description of a Neutron Star that I have seen
Thank you for explaining reverse-beta decay so well. This video answered a lot of questions I had about neutron stars!
You're welcome :-)
Stellar as always. Neutron stars are too weird to not explore. Can you do a video on supersymmetry?
I wouldn't call a Neutron Dwarf (ND) a 'star', because it's a CORPS of the star! Just like a WD. But thanks to this video I finally realize of how 'r-process' works -- 3:30. When 2 ND collides -- their crust opens and the inner neutronium immediately decays into lanthenides & other super heavy elements. Thanks, dude!
You're correct. It's technically not a "star," so it's terrible name... but we're stuck with it for now.
Love your videos, thanks for helping lots of people learn. Keep up the great work
You are AWESOME!!! I've learned much... A big thank you Nick...
Gee Whiz. These are the best videos. You don't talk down to viewers and you give just enough information to make the subject interesting but no so much that watchers drown in data. Also these five minute blips take a lot of editing, so how do you do it?
+1 sub, mostly because i love this junk (its what im studying in school 😁) and in hopes that you post often
Honestly my favorite youtubers barely make any videos :( upload more!
Would if I could!

see what I did there? 😃
Opening line. Hey SCI-LUM here
I'm a physics student from iran. Just wanted to say you have subs around the world:)
Nice little video.
You put a lot of hard work in. That's obvious. ☺
Your finger pointings are.. on point 😎
Woahhhh epilepsy warning!! - FAST FAST!!

I’ve just binged most of your videos and loved ever single one, thanks for putting your time into this, I know it’s not easy!
So sorry about the seizure! I really wish RUclips would let me add text to a video so I could add a warning.
I was only playing, no subscribers were harmed during this comment thread. :-)
Amazing video! Please continue! Possibly make a series with longer videos explaining a topic in detail? Perhaps general relativity?
happy teachers day.. celebrating in India
Thanks!
Hey Nick I subscribed! Personally I think you are on par with 'PBS spacetime' and 'Its ok to be smart' also PBS.
Great stuff man I really enjoy it
Please do a video on Tensor. Another awesome video Nick 👍

Great as always.
Great video Nick. But you should have included something about Magnatars.
You deserved a spoon of the nobel prize on gravitational detection
Awesome video dude :D Keep it up; we all love your effort and results :D
Have you ever payed close attention to the lyrics of the song "The Final Countdown" by the Swedish band Europe?
You can be pretty sure, that the writer of the lyrics didn't know anything about neutron stars. Or space in general.

Good riddance...! Ha ha...
I live close to where they started. Most people around here share their ignorance of astronomical matters.
After watching so many of your videos, I'm slowly starting to believe that your clone is real
most underrrated science channel on youtube...I swear youtube

thank you for all the work you put in
See a part of a neutron star's back from it's front? WOW!!
Your videos are awesome man! I subbed after watching just one of them. Would it be possible for you to do a video on TIME and TIME TRAVEL?
It's on the list :-)
Waiting eagerly to quench my thirst of time and time travel! P.S. I have to confess that I like your clone more than you lol
I love your videos so much
will tell many people here in Vienna to subscribe your channel, well, well deserved.. Thanks for this great videos...
what the heck this is like one of top 10 science channels on youtube but hasn't gained any attention yet...
Thank You Sir I learnt a lot from You
Liked and subbed.
Hey bro...yur book is amazing but i want more in that book ....
Still book is amazing..
I should write a second book that's all about the practical stuff (like optics).
Which book is that?
U r my favourite science channel
You can see its back from the front? Gravitational Lensing? How does that work? Awesome video
I can't put my finger on it... but I feel like the music editing for this episode was different. It's not better or worse... just different. Anyways... great video as always.
I switched everything over to Adobe Creative Cloud for this video... so it's probably not just the music.
I'm high right now,but Nick,lucid
Badum ts
On a serious note,love your videos
thanks for the lack of strobe warning at the pulsar section, holy heck

That's one of the reasons why you can press them closer to each other without overlapping and violating the Pauli exclusion principle.
The Blink of an Eye is an episode of Star Trek Voyager that involves a neutron star, and is the single best episode on Voyager.
Agreed. Great episode.
Big fan of your channel
I'm glad you found it then 👍
Thank you for your great videos.. :)
You're welcome! Glad you like them :-)
I LOVE THIS CHANNEL!
I like all your videos. Does a neutron star capture any significant percentage of the neutrinos that are passing through it ?
No, neutrinos are still too small. It probably stops a little more than something like Earth, but still doesn't stop that many.
Nice shirt. You saw the future!
Isnt the gravity well of a neutron star so strong that you'd become part of it when you get too close? good luck with your teaspoon :D
...good point.
Great man
Good video! Near the end you mention that neutron stars look weird up close. I've often imagined that from its surface, the 'horizon' would look weirdly high, i.e. the 'sky' would be less than 2 pi steradians.
Is this just due to the gravitational warping of spacetime, or would part of the neutron star's mass also "feel" above you? If the latter, would the gravity felt on the surface be less, since part of the neutron star appears above you? I've also wondered this about black holes where the 'sky' should appear as a tiny circle when looking from just above its surface.
It seems like every other scientist ignores key facts, exaggerates, or lies to us thru omission. Thanks you Science Asylum! I need my science dumbed down but I'm willing to hear the truth!
2:20 Fission... in a STAR?! Never head this before, and it sounds awesome.
Yep! It's called "photodisintegration."
Wow. Not to brag but this was like watching my own thoughts from 2 weeks ago or so > "It would explode!!"
Soz for the repost but ido watch yr vids over and over just incase ive missed something . Lol .
"You dead" hahaha that killed me
Will the normal reaction forces and frictional forces (that basically are electromagnetic forces) be present on a neutron star if it were completely made out of neutral neutrons?

Can you guys please make a video of similarities & difference between pulsars and magnetars. They are both neutron stars but how they came to be classified as either one has intriguied me forever.
Are you doing a video on Magetars?
Love this guy^^ Brings it into Lehman's terms.
neutron stars are my fav type of stars by name
Not to mention your spoon wouldn't be strong enough to scoop up neutron matter. Would love to see an update covering neutron pasta.
Please make a video on wormholes. please! please! please!
I am saving up for your text.
Slight error, Nick! At around 0:50 there's a diagram of the interior of a star. That diagram works well for the Sun, but for the kind of massive stars you're talking about that go supernova and form neutron stars, the radiation and convection zones would be the other way round!

But what if we scooped it up and brought it to ear-
It would explode
I fucking died
Neutron stars are my fav way better than black holes
Cuz they are way more violent
And have super strong magnetic fields

That might have been possible if RUclips thought otherwise. Minute Physics used to get >million view once. Now a days barely any science/engineering video get that much view.
I was wondering how something made up of mostly densely packed neutrons could produce a magnetic field. Thanks for clarifying.
Nice video, but try giving a heads up for an epilepsy warning
Hi there, can you make a video explaining neutron star quake?
Magnetars and star quakes.
I read through all the comments to make sure I wasn't asking a question that had already been asked and answered (Pauli Exclusion Principle for comments???)

Again, thank you for the time and energy you are devoting to this site, so much energy that you are warping space-time.
Neutrons are only stable inside a nucleus. _Free_ neutrons are _not_ stable (at least the way a free proton is stable). Free neutrons tend to only last a few minutes.
