Ever since learning about nuclear pasta (possibly containing strange matter) and learning that the heavy elements are most likely created by a kilonova (two neutron stars colliding). If these are true, neutron stars are by far the most important stellar object ever (in creating life, and if strange matter exists, destroying it). So fascinating.

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.

[@slinky_malinki5330]

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.

[@santos.l.halper1999]

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!

[@notsogreatsword1607]

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.

[@ryandelgo384]

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)

[@TheGreatTomdini]

@@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.

[@HotelPapa100]

[@thekingofmojacar5333]

Thank you SEA for this brilliant video! The death or end of a star is very different from the end of the universe. The universe does not collapse, its elastic bubble just becomes dark, cold and devoid of matter, and then it renews itself into a new bubble, rapidly growing and expanding inside... The matter, particle and energy boost is realized by quasars, they probably form a large quasar group, because the "dying" universe has a very large dimension, which is then gradually replaced by the new (universe) bubble... Stars collapse very violently and end up turning into dwarf stars or black holes and also this phenomenon here, the fascinating neutron stars, pulsars and magnetars... After about 20 million years, this essential core or nucleus loses all its power and ends up in a violent extremely luminous supernova...

[@starcitizen890j5]

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.

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.

These videos are excellent. Thank-you for creating and sharing for all!

I can't get over how fast these things spin

[@notsogreatsword1607]

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.

[@Unfiltered_Garbage]

Pulsars are so fascinating yet a bit terrifying.

[@AngeloXification]

It really puts into perspective the world of the subatomic if we consider that it isn't even possible to have "a teaspoon" of neutron star since it's impossible to even separate a teaspoon of it without it exploding into "uncompressed" matter.

[@joshuapatrick682]

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.

you just hear the vela pulsar sound in background of video, love that 11x per second revolution noise.

With someone who has a restless mind and insomnia, your videos help me go to sleep. Thanks!

[@chrisdjernaes9658]

Truly Awesome. Thanks for explaining and giving powerful perspectives on these terrifying objects.

[@Turrbo]

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 :)

[@margaretcooper797]

Interesting and very well researched making sense of what is very complex science.

Graveyard starcore is probably the coolest name i've heard for neutron stars, which by itself is already a cool name

[@Dinjur]

Can anyone tell me the source for the footage at 19:42? It's a great example of lensing from an object that's not a black hole and I'm wondering if anyone knows the video title

[@avinashprusty7519]

I love how the video starts with the sound of a pulsar.

[@arnoldthomsen6571]

Love the sound from the crab nabula in the start.

Don't take a laptop to a Neutron Star... Got it.

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. 👍 👍

[@stephenmedley5844]

He mentioned it, but it was too short. The real impressive reason why its called a neutron star is the fact that the iron core gets that much crunched, the electrons fuse into the protons which become neutrons then, which add up with the already existing neutrons of the iron atoms.. As a result there is no iron anymore, just a extreme high dense lump of neutrons.

[@jastrapper190]

If a black hole is collapsing indefinitely, does that mean that matter that “falls into” a black hole will fall indefinitely? Why do we assume a black hole has an infinitely small volume when all the matter that makes up the black holes mass is never able to reach its center? It seems logical to me that it’s impossible to ever touch an infinitely small object seeing that any distance you move toward it will always fall short of the distance needed to reach it.

[@NortheastSurvival911]

We come up with a word called singularity when mathematics don't answer questions. Singularity equals black hole equals we don't know what the fuck any of it is. We do not know what happens inside the event horizon. We don't know what happens at the singularity and we will never know. It's impossible it is 100% guaranteed impossible for humans to ever know what happens inside of one unless you go into one. And then maybe you'll know for a few seconds depending on the size of the black hole but you're never going to be able to get information out. There is no certainty. Of anything other than we know that they have shitloads of density and there's an event horizon where nothing can escape from. Aside from that who knows? Maybe we live in a black hole? I don't know. I'd like to think that when we die hi in this lifetime maybe then we will have the answers. But until then there's just certain things we as humans will never ever become aware of. And what happens on the other side or inside rather of an event horizon is one thing we will never understand. a roadblock with mathematics when it comes to gravity and whatnot is called singularity in singularity means we don't have a clue.

[@jastrapper190]

@@NortheastSurvival911 If we don’t know anything about them… I hesitate to make such statements. The Big Bang was a singularity and all of that matter, information, and energy…. Well it sure wasn’t lost for “eternity”.

[@jastrapper190]

@@NortheastSurvival911 It’s like we came up with “The Earth is flat” or “the stars are holes in the sky where heaven shines through”… when confronted with another situation humanity has no understanding of. Infinitely small Singularity… flat Earth… it matters little that at the time these words were spoken they were completely false.

[@RogerThat1977]

Still love this video. My favourite in the library

[@marekmasar5216]

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..

[@medexamtoolscom]

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.

[@marekmasar5216]

@@medexamtoolscom I agree with that, now days it is.. Just like cowards and criminals are rewarded and hero's are punished now days..

[@davidowens1132]

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.

[@warrenroach3026]

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 .

[@warrenroach3026]

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 .

[@ClaseeAzphukAnonIND]

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.

[@embe5100]

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!

[@kvonIII]

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.

[@SugarfreeYT]

Thank you I was thinking this.

[@leemottram6356]

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

[@jeffrule3787]

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.
