He has a calming voice, and ruminating over the magnitude of space tends to squash all the smaller anxieties within us, which often lead to troubles falling asleep.

Insert ports analogies here" and it`s not exactly relaxing hehe Edit: good thing someone liked that comment so I could fix that typo hehe xD
It's nice to let an orderly presentation of interesting facts run through the mind as you're trying to sleep. It's like somewhere between a bedtime story, a campfire tale, and a deep conversation.
Space, astronomy, and the universe, are in my opinion, the most fascinating field of study in existence. There is so much out there to inspire awe....Imagine what may yet to be discovered?
Not just any star!!! Supernova Type A are pretty rare .. Too small and you get a White Dwarf, too big and you get a Black Hole... But universe is big ass place and it's not like we have a shortage of stars..
We felt the energy of 2 objects more or less 20km of diameter, colliding with each other 100 millions light-years away from us. Damn....... i am out of words how epic this is .

I love how you described the tiny millimeter thick landscape as “mountains” . Neutron stars are so amazing. Think about how any object accelerates down towards the earths gravitational field at 9.8 m/s squared. If a teaspoon would accelerate to the speed that you mentioned then any object will also accelerate to that speed barring any angular momentum if they already have. As always great video I put on one of your playlist every night before bed and just Nerd out.
17:54 The heavy elements were not cooked up in the stars that came before them. They are basically fission products of the neutron star, which can be viewed as one giant atomic nucleus.
Great video! Apparently, NASA just mapped the surface of a neutron star, and found that the "hotspots" where radiation was emitted were in strange places. You mentioned that neutron stars all emit radiation from their poles, but one pulsar was found to have multiple hotspots in the southern hemisphere, and none in the northern hemisphere, making it one of the most unique pulsars out there.
The hotspot emissions were nowhere near the power of the polar beams. It was the first time to map a surface so it is not certain this discovery makes the star unique!
Michael Jordan Yeah calling it unique is a mistake at this point. It's unique in that its the only observed in such a way but going beyond that and calling it unique among stellar objects is not an assertion that we can make just yet. We just don't know enough to say that.
Tom Easton neutron stars are one of the strangest objects in the universe if it were any denser it would become a black hole so what we are looking at is like a black hole but still a star and we can actually get a chunk of it my theory is that there’s a small black hole in the center of the neutron star and the black hole can’t absorb the rest of the neutron star and when an object gets close the mass goes to the neutron star not the black hole so when the neoutron is at its final stage the black hole will absorb the neutron star and become a full black hole ( this is basically the quasi star which is hypothetical)
@@ryandelgo384 If a black hole were at the center of a neutron star, there would be nothing to stop it from feasting on the dense nuclear material around it. It would tear the neutron star apart and simply become a larger black hole and start doing its black hole thing. Neutron stars can become black holes by accreting enough mass, you're correct about that! It's possible the neutrons break down into a quark-gluon plasma at the center of the neutron star (neutrons are made of quarks). The conditions required to maintain a stable quark-gluon plasma are unthinkable.
Magnetars are hands down, the scariest boogiemen in the universe. I remember reading about a magnetar forming inside a supermassive star, and causing an explosion that sterilized everything within a thousand light-years or something
I saw something about that. That magnetar fucked that star all up. Like real real bad and then after a short while like you said boom. Everything within a thousand light years or so just.. obliterated
I put this guys videos on to fall asleep to, but in a good way. The way he presents this information is both intriguing and soooo soothing. Please don’t stop making these videos man!
The into background sound was awesome. That’s the insane rotation speed of a neutron star converted into audio. One of the most extreme examples of Conservation of angular momentum in the universe.
Every time I'm watching your video I'm shocked when it's ending and want to see more of it. How good you're a presenter you have no idea man! Love ever moment
The idea to use pulsars as a map to find our solar system, dates back to early 70's, when plaques were installed to Pioneer 11 and 10. They were designed by Carl Sagan and Frank Drake. That would have been a way better example, because it seems everyone will know Voyagers, but not Pioneer probes, which were the first to have a "calling card".
At 2:26 it's not only "bouncing off" the core, essentially the matter falling in gets so compressed and heated up it reaches the next threshold (where it previously failed which caused the fusion to cease) in which it produces the heavier elements by runaway fusion.
With only 10 000 miles between you and a magnetar, you will find yourself facing many detrimental physicals effects, among which having the iron ripped from your body is one of the least worrisome.
Well done thanks. I first heard recording of pulsars as a teenager. After it was explained to me that a object the size of San Francisco but twice the mass of the sun was spinning at 40,000 RPMS, my hair stood on end. Now whenever I hear the recording of a spinning neutron star it effects me in a visceral manner. To hear these objects reminds me that the universe is indeed queerer than I can imagine yet is as real as objects here on earth.
I really like how the Sound of the neutron star pusling is like a massive bouncing ball off a thin metal sheet, and the imaging of it looks like an earthquake fissure. Scientists discover new forms of mass every now and then, I bet you can make exotic materials with the energy of a neutron star that has a higher complexity of properties than ones we can even imagine, dwarfing graphene and nanomaterials completely
I've seen the Voyager record mentioned countless times on science shows but they usually just play clips of people saying "Hello" in different languages. I've never heard an explanation of what that picture on the disk actually means - so cool to find out it's a pulsar map!
The Universe becoming aware of itself is mind bending. Intelligent enough to create instruments to view what physics chemistry well all science put together can do 😁 so beautiful!
Thanks once again for the immense effort in creating this video which I enjoyed thoroughly. Can never tire of this subject as neutron stars are wildly fascinating.
"most of the time it does so in an incredible fashion¨ - actually, no. most stars just gradually cool off and become white dwarfs. only a few percent go supernova.
what? Lol Its a teaspoon of neutron stars only, not the entire thing. So it is the teaspoon of matter thats going at 20k km/s not the earth. Earth is much more massive than 100 million tons
@@_skyywave9740 I meant the ground that the teaspoon of stuff is falling towards. It's falling towards the surface of a neutron star, not towards the surface of the Earth. Secondly, movement is relative, so the ground is just as well falling towards the teaspoon. :)
Yes that got me too. The way he says it suggests that gravity on earth is dependent on the falling objects mass. NASA have a good video of a hammer and feather falling to earth in a vacuum chamber at exactly the same speed. In fact I am fairly sure I have also see a NASA video of astronauts doing the same thing on the surface of the moon too. So a tea spoon of neutron star matter assuming it’s not a large proportion of the earths mass would only accelerate at roughly 9.81ms^2. Of course if it was say 1% of the earths mass then you would need to increase the acceleration by 1% because the earth would actually fall upward to the spoon at 1% of 9.81ms^2. On the surface of a neutron star the gravity is going to be many millions of times more that 9.81ms^2. So yes dropping a teaspoon on the surface of neutron star would indeed travel much much faster than here on earth.
Mentioning the role of Anthony Hewish and not his graduate student Jocelyn Bell in the discovery of pulsars perpetuates one of the greatest injustices in the history of modern science.
You sure are 100% correct. I agree. That woman is damn nearly forgotten by most... I'm glad to see that you and a handful of other individuals on this thread aside from myself are aware of this. "LGM1 &LGM2" 🔥
I've been watching Sea for a very long time now, and I always come back to this video. This is to me the most fascinating, and incredible video I've ever seen.
I'm pausing this video to write this review! The background music is literally the would of a neutron star.. 😍😍😍 Hats off to you!! Please keep this amazing content going
Jocelyn Bell Burnell actually discovered the pulsars. Although she doesn’t believe that she should have also been awarded the Nobel Prize in physics because she was a grad student, she is generally thought of as the one who discovered and had evidence of neutron stars/pulsars.
misogyny she deserved the Nobel . Fred Hoyle was also denied a Nobel for championing her cause in the 1970s even though he was the main senior author of the Nobel winning paper Stellar Nucleosynthesis 1958 the most cited paper in 20th century Astrophysics
3:47 animations like this just scare me on a primal level. Theres no way i can even imagine something so powerful, but even when my brain tries, i just get scared.
Such an incredibly well researched and well made video! As an avid space enthusiast I’m so impressed and eager to share with family & friends since it’s easily digestible for all kinds of ppl. Thank you sir!!!
Well there’s direct core collapse, un-nova, or they simply fizzle out over immense timespans but that’s not interesting to someone who’s being told about the wonders of the universe for the first time. Point taken tho.
You know what bends my mind about this. If we observe something that is say.. 100 million light years away, that means that we are seeing light that traveled for so long, that the event itself occurred long before humanity and we are only just seeing it now. Furthermore the idea that there are probably events happening right now that humanity will never witness, means there could be a deadly gamma ray burst hurtling towards us right now, impending doom, and yet, we won't even know it for hundreds of thousands of years. On a universal scale, we claim to have a basic understanding of the universe but we are in fact blind. It's humbling to know that despite all our understanding of the universe, we are no closer to answering the bigger questions than we were 100 years ago.
Is is possible, instead of speaking of "the straw that broke the camel's back", to speak of "the hydrogen atom that transformed the neutron star into a black hole"?
@@jengleheimerschmitt7941 Still, the idea behind the question is interesting. Something as small as an atom can trigger one of the most violent event in the universe as it's mass tips the scale towards a black hole.
@@rundownaxe ...Imagine if someone started droping camels onto a neutron star that was just shy of collapsing into a black hole. One of them would be the camel that collapsed the neutron star into a singularity. ...so to speak... 😁
4:07 A photo of Fritz Zwicky actually SMILING?? That's as rare as anything found in deep space! Thanks for another great documentary my friend. Very good stuff indeed. 👍 👍
As always top notch quality and an exceptionally good story-telling. It's only a question of time until your channel experiences a supernovae, before collapsing into a magnetar - consuming every person getting within the gravity field of your content.
It wasn't hewish who discovered it!!! It was Jocelyn Bell alone.. Hewish was her professor and she shared her find for witch he was rewarded Nobel Prize next year... He basically stole the Prize from her for such significant discovery..
This is a common story in science. I have it on good authority (from Nick Holonyak, inventor of the LED, who was an intern at Bell labs at the time) that Shockley had NOTHING to do with the invention of the transistor, all he did was sign his name and steal the credit for it from those working at the lab he was the administrator of.
Thomas Edison did the same thing to his assistant, so not new at all. And the fact that in the 60's (?) a woman getting the real credit for something scientific? Not very likely, unfortunately.
lets not forget Michael Faraday the scientist was accused by his boss Humphry Davy of stesling his work to do with magnetism, which was not true also Faradays genius would go on to be proved time and time again.he was actually on the right track what he made was a basic motor ,motion by electro magnetism the start of all electric motors .
actually i invented faster than light travel without the math it was an intense thought experiment not unlike Einstein would do before the math ,i went on to find that it had already been thought of and the maths by mexican theoritic physicist Miguel Alcubierrie did i create it or did it pop in to my brain as i thought ha ha who can tell .
Black holes are essentially pockets of space time that exist outside of the laws that govern our universe. Neutron stars are still bound by those laws but the deep interior is likely experiencing states that we cannot understand so the effect is similarly mysterious.
SEA: I am very impressed with your videos you do exemplary work l and it shows a level of professionalism that I really respect. I remember when Black Holes were still only a “Theory” as they were not proven. My favorite series was Cosmos and that is where you and the late Carl Sagan have something in common. The ability to explain something that is very complex to someone and not appear condescending. Keep up the great work
So glad you like the videos, it is a dream to channel Sagan in any way given the profound eloquence and succinctness he had in summarising the cosmos. Also thank you very much for your donation 💙 🙏
Anyone notice watching astronomy videos is a different experience depending on time of day. About 4am is my fav. 9:45am is least fav. Always better before bed than walking up.
Love your content.. Not enough interest given to neutron stars.. It varies however I believe finding the most dense form of matter known to exist deserves intense interest.
(6:22) This shoulder-height drop speed measurement breaks with gravitational acceleration on Earth. A teaspoon size of neutron star matter (assuming one could keep it in such a state without the crushing gravity of the neutron star) dropped from shoulder height should have the same acceleration as a rubber ball dropped from the same height. The only difference between the two objects would be atmospheric friction.
Thanks, I had to pause the video and check in the comments if someone mentioned that or if It meant the earth would accelerate into the teaspoon due to its mass. Seemed a bit too heavy
Even when its something I may have already known it is mind blowing hearing about the properties of neutron stars. Besides it's always helpful to hear about a given topic from many different sources. I find that I nearly always contact away with a deeper understanding of the subject.
6:25 if you where able to drop it from shoulder height the acceleration at earths surface does not change. And the object would accelerate at 9,81 ms². Its only the mass of the earth that matters not the mass of the faling object if you want to determine the acceleration due to gravitation in a vaccum. the formula is: Force = (G * Mass1 * Mass2) / Distance². I realy like the rest of this video thou!
See the famous Apollo 15 hammer/feather drop on the moon. It's details like this that give me pause deciding whether or not to continue watching these videos. If you can get such a fundamental concept so wrong, then it calls into question everything else being stated as fact on here.
Was looking for a comment on this, glad I’m not the only one who found it strange that he thinks the earths gravity would somehow get stronger the heavier an object is
I was about to reply as you did but was sure someone called it out. I stopped watching the video at 6:33 because of his statement. I wonder how he even came up with that obituary velocity.
I like this series. The narrative explains these amazing celestial phenomena from the perspective of theory combined with observation from a great distance, resulting in our best guess at their true nature. The vast majority of other narratives suffer from a scientific arrogance that borders on religious orthodoxy.
Great video, always looking forward to seeing that notification with the word SEA included! Love your astronomy videos just as much as your past GD videos :)
Imagine being born from a gas cloud, becoming a star, getting old a dying, becoming a neutron star, then finding yourself a buddy, warping spacetime with them, colliding with them, exploding, your molecules being caught on an asteroid, that asteroid somehow getting to Earth, becoming one with the planet, being mined up by humans, and used for someone's mobile phone (or whatever it is we use these heavy elements for)
one thing: neutron stars spin so fast because angular momentum is preserved, they are so small compared to a main sequence star they spin extremely quickly
@@Lunar_lunaa It was mentioned, but barely. I got to meet her once though. She is really cool. I was attending Texas A&M - Commerce and she gave a talk. Was a packed room.
@@Maadhawk Wow! I won’t lie, I’m a little jealous. I’ve watched a ton of her talks and lectures on TH-cam and she seems like a really cool woman. Glad to know she actually is!

Neutron stars are incredible, they might actually help us understand what the "inside" of a black hole might look like
How?
Lol
@@CsykKrit It's similar, a really dense object.

The idea to use pulsars as a map to find our solar system, dates back to early 70's, when plaques were installed to Pioneer 11 and 10. They were designed by Carl Sagan and Frank Drake.
That would have been a way better example, because it seems everyone will know Voyagers, but not Pioneer probes, which were the first to have a "calling card".
At 2:26 it's not only "bouncing off" the core, essentially the matter falling in gets so compressed and heated up it reaches the next threshold (where it previously failed which caused the fusion to cease) in which it produces the heavier elements by runaway fusion.
Magnetars are so magnetic that they could rip the iron out of your blood at a distance of over 10,000 miles!
WOAH. Coooooooooool.....
Thatdudedevlin 07 till it happens to you
Meh
With only 10 000 miles between you and a magnetar, you will find yourself facing many detrimental physicals effects, among which having the iron ripped from your body is one of the least worrisome.
@@AndreasRavnestad true! Crazy how something so majestic and amazing could also be so deadly
bruh this one truly blew my mind.. the scale of such events is incomprehensible.. cheers for instilling this feeling.. wow
9:55 Pretty crazy that Joy Division invented Neutron Stars
Mental isn't it
O
LoL
Well done thanks. I first heard recording of pulsars as a teenager. After it was explained to me that a object the size of San Francisco but twice the mass of the sun was spinning at 40,000 RPMS, my hair stood on end. Now whenever I hear the recording of a spinning neutron star it effects me in a visceral manner. To hear these objects reminds me that the universe is indeed queerer than I can imagine yet is as real as objects here on earth.
The sounds in the beginning are terrifying imagine hearing that in space and infront of you a neutron star
Glad I am not the only one creeped out by that! It sounds like something you'd use in a horror film to signify an evil presence.
Don't worry, this couldnt happen since you can't hear sounds in space
I really like how the Sound of the neutron star pusling is like a massive bouncing ball off a thin metal sheet, and the imaging of it looks like an earthquake fissure. Scientists discover new forms of mass every now and then, I bet you can make exotic materials with the energy of a neutron star that has a higher complexity of properties than ones we can even imagine, dwarfing graphene and nanomaterials completely
I've seen the Voyager record mentioned countless times on science shows but they usually just play clips of people saying "Hello" in different languages. I've never heard an explanation of what that picture on the disk actually means - so cool to find out it's a pulsar map!
The Universe becoming aware of itself is mind bending. Intelligent enough to create instruments to view what physics chemistry well all science put together can do 😁 so beautiful!
I love when old friends are interested in the stuff I am, currently pursuing an Astrophysics degree! Hope YT has been well for you!
Sodium you go well in guacamole
Thanks once again for the immense effort in creating this video which I enjoyed thoroughly. Can never tire of this subject as neutron stars are wildly fascinating.
"most of the time it does so in an incredible fashion¨ - actually, no. most stars just gradually cool off and become white dwarfs. only a few percent go supernova.
@Jean-Paul Teitu II yes, but such stars are only a tiny fraction of the star population.
Jean-Paul Teitu II the vast majority of stars are red dwarfs.
6:30 "falling at well over 20 000 km/h when hitting the ground" - that is, the ground of the neutron star, not the Earth. I got confused there. :)
what? Lol
Its a teaspoon of neutron stars only, not the entire thing.
So it is the teaspoon of matter thats going at 20k km/s not the earth. Earth is much more massive than 100 million tons
@@_skyywave9740 I meant the ground that the teaspoon of stuff is falling towards. It's falling towards the surface of a neutron star, not towards the surface of the Earth. Secondly, movement is relative, so the ground is just as well falling towards the teaspoon. :)
Yes that got me too. The way he says it suggests that gravity on earth is dependent on the falling objects mass. NASA have a good video of a hammer and feather falling to earth in a vacuum chamber at exactly the same speed. In fact I am fairly sure I have also see a NASA video of astronauts doing the same thing on the surface of the moon too.
So a tea spoon of neutron star matter assuming it’s not a large proportion of the earths mass would only accelerate at roughly 9.81ms^2. Of course if it was say 1% of the earths mass then you would need to increase the acceleration by 1% because the earth would actually fall upward to the spoon at 1% of 9.81ms^2.
On the surface of a neutron star the gravity is going to be many millions of times more that 9.81ms^2. So yes dropping a teaspoon on the surface of neutron star would indeed travel much much faster than here on earth.
@@starcitizen890j5 Still, you wouldn't want to drop it on your foot..
@@starcitizen890j5it would fall faster
Mentioning the role of Anthony Hewish and not his graduate student Jocelyn Bell in the discovery of pulsars perpetuates one of the greatest injustices in the history of modern science.
You sure are 100% correct. I agree. That woman is damn nearly forgotten by most... I'm glad to see that you and a handful of other individuals on this thread aside from myself are aware of this.
"LGM1 &LGM2" 🔥
I've been watching Sea for a very long time now, and I always come back to this video. This is to me the most fascinating, and incredible video I've ever seen.
I clicked *faster than the speed of light*
ME TOO !!!!
That pun though
Me 3!!!
You fell for it?
Wow you must have a really heavy and bright finger then :D
I'm pausing this video to write this review! The background music is literally the would of a neutron star.. 😍😍😍 Hats off to you!! Please keep this amazing content going
Jocelyn Bell Burnell actually discovered the pulsars. Although she doesn’t believe that she should have also been awarded the Nobel Prize in physics because she was a grad student, she is generally thought of as the one who discovered and had evidence of neutron stars/pulsars.
Thought by no one.
@@Szgerle Hate. Why so much hate, delusional kid?
@@hamzaijaz4133 What are you screaming on about?
misogyny she deserved the Nobel . Fred Hoyle was also denied a Nobel for championing her cause in the 1970s even though he was the main senior author of the Nobel winning paper Stellar Nucleosynthesis 1958 the most cited paper in 20th century Astrophysics
3:47 animations like this just scare me on a primal level. Theres no way i can even imagine something so powerful, but even when my brain tries, i just get scared.
This video was great. I just searched Neutron Star to learn about them. Had never heard of your channel. But I'm going to subscribe. Great work.
So awesome that that's where the cover of Unknown Pleasures comes from.
Such an incredibly well researched and well made video! As an avid space enthusiast I’m so impressed and eager to share with family & friends since it’s easily digestible for all kinds of ppl. Thank you sir!!!
Before you do so, fact check his claim that most stars go with supernova bang. It is horribly wrong...
Well there’s direct core collapse, un-nova, or they simply fizzle out over immense timespans but that’s not interesting to someone who’s being told about the wonders of the universe for the first time. Point taken tho.
I enjoy these educational videos. I always love learning about the way our universe works. There is always something new to learn.
You know what bends my mind about this. If we observe something that is say.. 100 million light years away, that means that we are seeing light that traveled for so long, that the event itself occurred long before humanity and we are only just seeing it now. Furthermore the idea that there are probably events happening right now that humanity will never witness, means there could be a deadly gamma ray burst hurtling towards us right now, impending doom, and yet, we won't even know it for hundreds of thousands of years. On a universal scale, we claim to have a basic understanding of the universe but we are in fact blind. It's humbling to know that despite all our understanding of the universe, we are no closer to answering the bigger questions than we were 100 years ago.
you just hear the vela pulsar sound in background of video, love that 11x per second revolution noise.
Is is possible, instead of speaking of "the straw that broke the camel's back", to speak of "the hydrogen atom that transformed the neutron star into a black hole"?
Yes. That rolls off the tongue much better. 😁
The proton that core-collapsed the neutron star into Singularity.
@@jengleheimerschmitt7941 Still, the idea behind the question is interesting. Something as small as an atom can trigger one of the most violent event in the universe as it's mass tips the scale towards a black hole.
@@rundownaxe ...Imagine if someone started droping camels onto a neutron star that was just shy of collapsing into a black hole. One of them would be the camel that collapsed the neutron star into a singularity. ...so to speak... 😁

Excellent video! I had been looking for a good video about Neutron Stars for a while!
I love how the video starts with the sound of a pulsar.
This is the best Neutron Star content I've seen anywhere. Congratulations to the author.
4:07 A photo of Fritz Zwicky actually SMILING?? That's as rare as anything found in deep space! Thanks for another great documentary my friend. Very good stuff indeed. 👍 👍
Great insight buddy. I never new about the reverse pulsar location thing on the golden record....Thumbs up.
As always top notch quality and an exceptionally good story-telling. It's only a question of time until your channel experiences a supernovae, before collapsing into a magnetar - consuming every person getting within the gravity field of your content.
The small size of a neutron star helps one to realize just how much empty space is between the atom's nucleus and it electron shells.
With someone who has a restless mind and insomnia, your videos help me go to sleep. Thanks!
Best lullaby on TH-cam. You are not boring at all. But your videos put my mind at ease. I still retain a lot of it when I wake up.
Interesting and very well researched making sense of what is very complex science.
When the alien capture the Voyager spacecraft, I'm sure they come to earth for record player.
I can't get over how fast these things spin
The more I discover about space, the more I see what a miracle life on Earth actually is. Absolutely fascinating.
Life isn't a miracle, it's just bloody minded
Things I learned today: Iron formation is basically a solar self-destruct button.
It wasn't hewish who discovered it!!! It was Jocelyn Bell alone.. Hewish was her professor and she shared her find for witch he was rewarded Nobel Prize next year... He basically stole the Prize from her for such significant discovery..
This is a common story in science. I have it on good authority (from Nick Holonyak, inventor of the LED, who was an intern at Bell labs at the time) that Shockley had NOTHING to do with the invention of the transistor, all he did was sign his name and steal the credit for it from those working at the lab he was the administrator of.
@@medexamtoolscom I agree with that, now days it is.. Just like cowards and criminals are rewarded and hero's are punished now days..
Thomas Edison did the same thing to his assistant, so not new at all. And the fact that in the 60's (?) a woman getting the real credit for something scientific? Not very likely, unfortunately.
lets not forget Michael Faraday the scientist was accused by his boss Humphry Davy of stesling his work to do with magnetism, which was not true also Faradays genius would go on to be proved time and time again.he was actually on the right track what he made was a basic motor ,motion by electro magnetism the start of all electric motors .
actually i invented faster than light travel without the math it was an intense thought experiment not unlike Einstein would do before the math ,i went on to find that it had already been thought of and the maths by mexican theoritic physicist Miguel Alcubierrie did i create it or did it pop in to my brain as i thought ha ha who can tell .
These videos are excellent. Thank-you for creating and sharing for all!
Joy Division's first album was so good that they turned the cover art into a real thing!
Black holes are essentially pockets of space time that exist outside of the laws that govern our universe. Neutron stars are still bound by those laws but the deep interior is likely experiencing states that we cannot understand so the effect is similarly mysterious.
SEA: I am very impressed with your videos you do exemplary work l and it shows a level of professionalism that I really respect. I remember when Black Holes were still only a “Theory” as they were not proven. My favorite series was Cosmos and that is where you and the late Carl Sagan have something in common. The ability to explain something that is very complex to someone and not appear condescending. Keep up the great work
So glad you like the videos, it is a dream to channel Sagan in any way given the profound eloquence and succinctness he had in summarising the cosmos. Also thank you very much for your donation 💙 🙏
Pulsars are so fascinating yet a bit terrifying.
Neutron Star: Who are you??
Magnetar: I am you... but stronger.
Truly Awesome. Thanks for explaining and giving powerful perspectives on these terrifying objects.
Anyone notice watching astronomy videos is a different experience depending on time of day. About 4am is my fav. 9:45am is least fav. Always better before bed than walking up.
Thank you for your videos! They're so well done--the material, the information, the cinematography, and your voice is perfect for this
Love the sound from the crab nabula in the start.
Love your content.. Not enough interest given to neutron stars.. It varies however I believe finding the most dense form of matter known to exist deserves intense interest.
(6:22) This shoulder-height drop speed measurement breaks with gravitational acceleration on Earth. A teaspoon size of neutron star matter (assuming one could keep it in such a state without the crushing gravity of the neutron star) dropped from shoulder height should have the same acceleration as a rubber ball dropped from the same height. The only difference between the two objects would be atmospheric friction.
Thanks, I had to pause the video and check in the comments if someone mentioned that or if It meant the earth would accelerate into the teaspoon due to its mass. Seemed a bit too heavy
Dimond planets, the ultimate in space bling.
Some marketing scheme in the far future.
Graveyard starcore is probably the coolest name i've heard for neutron stars, which by itself is already a cool name
Even when its something I may have already known it is mind blowing hearing about the properties of neutron stars. Besides it's always helpful to hear about a given topic from many different sources. I find that I nearly always contact away with a deeper understanding of the subject.
6:25 if you where able to drop it from shoulder height the acceleration at earths surface does not change. And the object would accelerate at 9,81 ms². Its only the mass of the earth that matters not the mass of the faling object if you want to determine the acceleration due to gravitation in a vaccum. the formula is: Force = (G * Mass1 * Mass2) / Distance².
I realy like the rest of this video thou!
See the famous Apollo 15 hammer/feather drop on the moon. It's details like this that give me pause deciding whether or not to continue watching these videos. If you can get such a fundamental concept so wrong, then it calls into question everything else being stated as fact on here.
Thank you I was thinking this.
Was looking for a comment on this, glad I’m not the only one who found it strange that he thinks the earths gravity would somehow get stronger the heavier an object is
I was about to reply as you did but was sure someone called it out. I stopped watching the video at 6:33 because of his statement. I wonder how he even came up with that obituary velocity.
I like this series. The narrative explains these amazing celestial phenomena from the perspective of theory combined with observation from a great distance, resulting in our best guess at their true nature. The vast majority of other narratives suffer from a scientific arrogance that borders on religious orthodoxy.
Unknown Pleasures is my all time favourite album and until today I had no idea that's where the cover came from.
Awesome, a photo of a smiling Fritz Zwicky instead of scowling! Thanks for posting this for all of us to enjoy my friend, really good stuff! 👍 👍
Still love this video. My favourite in the library
Great video, always looking forward to seeing that notification with the word SEA included! Love your astronomy videos just as much as your past GD videos :)
I watch this exact video every week about 2-5 times! I love the information and scaling figures, they are out of this world 🌎!
I just wish I could see a neutron star. I don't want to die without seeing something as magnificent as a neutron star
0:01 Nice touch to have the neutron star sound in the background to start off with.
Imagine being born from a gas cloud, becoming a star, getting old a dying, becoming a neutron star, then finding yourself a buddy, warping spacetime with them, colliding with them, exploding, your molecules being caught on an asteroid, that asteroid somehow getting to Earth, becoming one with the planet, being mined up by humans, and used for someone's mobile phone (or whatever it is we use these heavy elements for)
one thing: neutron stars spin so fast because angular momentum is preserved, they are so small compared to a main sequence star they spin extremely quickly
I never tire of learning about things like this. Great little film, this. Thanks for taking the time to make these. I love 'em!
Antony Hewit didn't notice the signal. Dr. Bell noticed it on her own with little to no supervision from Hewitt.
I was a little disappointed her name wasn’t mentioned tbh.
@@Lunar_lunaa It was mentioned, but barely. I got to meet her once though. She is really cool. I was attending Texas A&M - Commerce and she gave a talk. Was a packed room.
@@Maadhawk Wow! I won’t lie, I’m a little jealous. I’ve watched a ton of her talks and lectures on TH-cam and she seems like a really cool woman. Glad to know she actually is!
I actually saw this video at school in physics. I love the video.
I already knew 75% of this, but I still enjoyed it. Your presentation is very good.
