Indeed, it's pop science; give what the ignorant masses from the high priest of pseudo-cosmology what they want. There was the black hole, then neutron star, then white dwarf and now this. All of them were invented here on earth to cover up for the shortcomings of gravity-centric cosmology. Keep the taxpayers $$$ coming. What will be next? String star? Even Eisenstein will be rolling in his grave.
Well a magnetar is just part of the evolution of a star so in theory our very own sun could evolve into a mini magnetar bringing it much closer to home. Of course though by then humans will be long extinct so it really won't matter to us anymore.
What I want to see is an artist's mind numbing rendition of a singularity. Then again, that is likely something only a descendant of that M. C. Escher fellow could pull off...
@@nowthatsjustducky There are mind-blowing scientifically accurate to our best understanding of a black hole in the context of our knowledge of physics (mostly general relativity) artist's version (but from mathematical models) of the "inside" ad "outside" of a black hole.
All this renditions are fiction, not one real picture of earth.all our artists or cgi, with 22k satellites as they say surely we would have pictures of earth. Lol. Also Hubble and others only have one camera angle,bs. If real they would have many angles in every direction. If you look not even that hard u will see all of space in a hoax. Just look at a Nikon 900 or 1000 and see these planets and stars are nothing more than lights.
I constantly thought "dash, not minus!" But he said it so many times that it made me doubt. So I looked it up: it should indeed be minus. Apparently the two numbers are "right ascension and degrees of declination", so you can get plus or minus depending on location (google pulsar nomenclature)
Idk why everyone is angry because he took more time to explain everything. Im stoned af and i enjoyed watching every minutes of this, good job man, great video, you have a new subscriber!
@@billf7585 Yeah, and as far as we know, Magnetars rotate. And even if the angle of polarity matches the angle of rotation exactly, there are still fluctuations in the density of the magnetic field, rotating with the Magnetar. Plenty enough, to harvest crazy amounts of power. This works even on earth but way to slow and weak for energy harvesting purposes.
@@te0nani : Gee teOnani you really know your stuff. I'm trying to come up with a toy for my grandson's next birthday and built a contraption with one magnet on a pendulum sweeping over another stationary one with same polarity.

How can I harness the fluctuating magnetism into something more visual for him? Thanks in advance.

Not only that but he stated that a neutron star comes from a super massive star going supernova. There's so much wrong with that statement that I'm convinced this was a first draft script for the opening of the JJ Star Trek movie.

The author basically mixed up Supermassive Stars and Massive Stars. (Supermassive is 30 Stellar Masses and above).
@Loki the sly one @ 5:24 we see "1E 1048.1-5937". How can that be coordinates? If you'd be right it's the difference between 2 numbers; one would expect (at least) 3 numbers to have coordinates. Besides, IF it's 2 numbers, then what is the "E" in the first one? Exponential notation? But "1E anything" is just 1! A bit unlikely, not?
@@jewboy7740 So, is that one number (not enough to be coordinates in space) or a subtraction of two numbers(idem)? If they ARE coordinates, please show me the 3 distinct numbers.
Wait a minute, if the lifespan of a magnetar is only about a million years then the ones we are detecting now probably aren't actually there anymore. This makes them popping up quickly around the galaxy (speaking in geological timespans here) very dangerous for the development of life.

Imagine a copper sphere the size of the sun coming close to a magnetar. Lenz Law but scaled up to insane levels. The magnetar would most likely rip itself apart and the copper sphere would probably be thrown light years away while boiling.
I was curious so I asked ChatGPT, here's it's response: A magnetar is a type of neutron star with an extremely powerful magnetic field, typically 1,000 trillion times stronger than Earth's magnetic field. If a copper sphere the size of the Sun were to come into proximity with such a magnetar, the interaction between the copper (a conductive metal) and the magnetar's immense magnetic field would be dramatic. Here's a breakdown of the most likely outcomes: 1. Induced Electric Currents and Electromagnetic Forces Copper is a good conductor of electricity, so as it enters the magnetar's intense magnetic field, immense electric currents would be induced in the copper. This would be due to Faraday's Law of Induction, which states that a changing magnetic field can generate electric currents in conductive materials. The electric currents in the copper would lead to significant resistive heating, causing the copper to rapidly heat up and potentially melt or vaporize. The interaction between the induced electric currents and the magnetic field would create extreme Lorentz forces within the sphere, potentially ripping it apart due to the immense stresses created by these forces. 2. Magnetic Field Effects on Copper's Structure A magnetar's magnetic field is so strong that it can distort atomic structures, even on the level of electron orbits. This intense magnetic field could alter the atomic structure of the copper, potentially compressing or even ionizing it. Copper atoms could experience quantum effects such as Landau quantization, where electron motion perpendicular to the magnetic field is restricted to discrete energy levels. 3. Extreme Heating and Vaporization The heat generated by the induced currents could be so intense that the copper sphere might not just melt but could vaporize entirely. Copper's melting point is about 1,085°C (1,984°F), but the heat produced in this situation would far exceed that. If the copper sphere vaporizes, the resulting cloud of copper plasma would interact with the magnetar’s magnetic field, possibly being shaped and confined by the magnetic field into complex structures. 4. Gravitational Effects Magnetars are incredibly dense, with gravitational fields much stronger than any ordinary star, including the Sun. The copper sphere, having a mass comparable to the Sun, would experience powerful tidal forces from the magnetar’s gravitational field, potentially leading to its deformation or even fragmentation. If the copper sphere were close enough to the magnetar, it might be pulled apart by tidal forces, and some of the copper could be accreted onto the magnetar's surface, adding to its mass. 5. Relativistic Effects and Radiation Emission Magnetars can emit high-energy radiation, such as X-rays and gamma rays. These emissions would likely interact with the copper sphere, leading to further ionization of the material and contributing to its eventual vaporization. The interaction between the copper sphere's plasma and the magnetar's magnetic field could produce relativistic jets or bursts of radiation, depending on the geometry of the encounter. 6. Potential for a Catastrophic Event Given the magnetar’s extreme conditions, the proximity of a large copper object could trigger instabilities in its magnetic field. The magnetar could release a powerful burst of energy known as a magnetar flare, which could release as much energy in a fraction of a second as the Sun emits in 100,000 years. The copper sphere would likely be completely destroyed in such an event, with any remaining material either ejected at high speeds or accreted onto the magnetar. In summary, the encounter between a copper sphere the size of the Sun and a magnetar would be catastrophic for the copper object. It would be subject to extreme electromagnetic forces, heating, vaporization, gravitational tidal effects, and potentially even powerful radiation bursts.
@5:46 understatement of the century! A golf ball dropped from 1 meter above the surface or a neutron star would hit it half a millionth of a second later, at a large fraction of the speed of light and with a force greater than all the thermonuclear weapons in the world combined. So yes, "A human would be torn to bits in a matter of seconds",... and then some!
I love it when we begin sentences with "despite our incredible technological advances..." and follow with the latest gaping hole in our understanding. I have a friend who happens to be a world-renowned physicist. When I told him 10 years ago about a popular book called "The End of Science," wherein the author claimed that we had pretty much worked out 99% of what there is to know about the universe, he laughed so hard that tears were streaming down his face and he couldn't even speak for a good 5 minutes. When he finally got ahold of himself again, he explained to me that the situation was exactly the opposite. Why do we always think we are so smart, so advanced? Just think about the barbaric methods that were the state of the art in medicine 100 or even 50 years ago. We are still just crawling out of our caves. We still don't even have a Unified Field Theory. We don't even really understand gravity yet. And don't even get me started on our barbarous societal arrangements (I mean, just consider America, the richest country in the history of the world, and the way it treats the vast majority of its citizens...)
you're right - many of my non-scientific friends dont seem to believe this - "We don't even really understand gravity yet" - but its perfectly true and TBH we dont even really understand electricity either - just because we use it does not mean that we understand it. As far as "understanding" anything goes, it seems that the harder you look the more you find - eg the many many forms of subatomic particles
@@j4y167 in UK for instance, tax is so ridiculous that you only get to spend around £20 from every £100 you earn - surely this cant be true you say - but it is - when 75% of the price of petrol is tax, 80% of the price of alcohol is tax & VAT on almost everything, you have income tax, corporation tax, national insurance, road tax, car tax, insurance tax, travel tax, inheritance tax, capital gains tax - the list is endless - we tax on top of tax on top of tax
"Which in essence is trillions of times that of the electromagnetic radiation on the earth". But isn't electromagnetic radiation in reference to, you know, the scale from radio waves to gamma rays? With visible light somewhere in the middle? That has nothing to do with neutron stars having a 10*13 Tesla magnetic field strength.... but okay, continue... hahaha
CJ White: That's what I love about TH-cam. Nothing should be taken too seriously but only thought provoking and good entertainment. You obviously are a learned gentleman and expect accuracy in scientific explanations.
the way you put the information is unbelievable, despite I know most of those pieces of information I watched the entire video, good work and good choice for the music too.
Kosmo, don't worry about the negative comments about your 'dramatic' style of presentation. you are a channel that i would put side by side with isaac arthur. It may well irk people already steeped in physics, but your delivery makes the subject matter very accessible to a larger audience. and it is necessary to have showmanship in voice over presentation.The mindblowing facts are usually lost if delivered in monotone voice, without appropriate pauses after significant statements.a channel has to be both entertaining and educational. Kosmo provides both. similar to isaac arthur, except the latter is more futurism e.g. detailed recreation of humanities first mass interstellar 'ark' to search for and colonise a planet in another star system when earth and all inner planets becomes uninhabitable with an expanding sun in about a billion years. His videos are truly epic and long. you do shorter snappier ones. and you are a very new channel in comparison. Also appreciate your voice/accent like isaac arthur rather than all those whiny american accents of millennials. Many non university educated people think science boring, because of a poor high school teaching experience.so dramatic entertaining presentation/teaching overcomes that. and science is really THE most important and relevant academic subject of them all, which includes its incorporation of many mathematical theorems. as for myself after gaining my undergraduate degree in the American studies school of my university, later in life cultivated a thirst for scientific knowledge about the universe, especially cosmology-astrophysics, experimental physics, planetary science, exo-chemistry/biology and marine biology. and took my physics BSc undergrad with the open university, with one free-choice module each semester, allowing me to take minors in my specific subjects of interest, as listed above. ninety percent from home, and ten percent was science field trips. most of the population of first world countries even are relatively scientifically illiterate-they never pick up science after high school again. in U.K it's worse as we leave high school at sixteen years old, with sixth form/college two fill the two year gap until university being purely voluntarily. . That is we can finish our education at sixteen, and usually only those aiming for university take their A levels at a sixth form/further education college. that means every American is receiving two more academic years of science curriculum physic chemistry,biology, and subcategories of physical geography like climate and weather science and geology. keep up the good content.
@Dominik yehaw⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻ Your? I didn't invent it. In fact if anything we use both systems all the time it is the rest of the world that gets confused so easily.
Nice video. A Suggestion: Please, refrain from really poor sentences like At 5:45 . Anything, including humans, would be torn to pieces and then desintegrated long, long before coling anywhere lcose to the surface. and it would go a lot faster than "a matter of seconds".
The most dangerous magnet in the universe! Except we don't have to worry about one, like ever, because the closest one to Earth is still multiple thousands of Light Years away, so... yeah... about that football game last night...
@Larry XK Humanity is literally a thousand times more likely to die from an Asteroid hit, than they are from a Magnetar drifting into our neighborhood in the next five hundred years. But you go ahead and keep being afraid of that thing that will never happen to us...
I love the comment that you cannot observe a 15 km diameter object that is 13000 light years away in a normal amateur telescope. It is a soft, subtle, but extremely heavyweight trolling worthy of a Monty Python show. I mean, what the hell!? How come such a ridiculously trivial statement ever be made!? Made my day.
"mom can I have a well made and scientifically accurate documentary about neutron stars?" mom: "we have well made and scientifically accurate documentary about neutron stars at home" well made and scientifically accurate documentary about neutron stars at home:
If - when FTLS is developed and utilized, it would seem a “Magnatar” would present a navigational nightmare in the scale of things if a “Magnatar” is 15 km in diameter, detection would be difficult at best.
Why are magnetars and neutron stars always portrayed as spinning spheres? Wouldn't something that massive and spinning that fast be more of a disk or a even a ring? And if the gravity well was strong enough to force it into a sphere, despite internal pressures and centrifugal forces, wouldn't it also be strong enough to collapse it into a black hole? And if it were in fact a ring, what would be the nature of space/time at the center of the ring? Just a musing from a high school drop out.
Totally true, for a stationery object. But don’t these things tend to spin, I mean like really fast, on a cosmic level type fast? The centrifugal forces of a spinning object that massive must be mind boggling. And as anyone knows, inertia is the one force that can challenge gravity on any level, any time, anywhere. So, just how fast can they spin?
@@ralphscholz9533 there's a pulsar in the Sagittarius constellation that spins about 700 times a second. The disc that you talk about is called an accretion disc, it appears as a disc to us, the observer due to the immense bending of light from behind the spherical blackhole. There's a fun video of veritaisum that explains it.
@@nawdudegaming9368 Yea, I know about the accretion disk. But that's for black holes, they have a much deeper gravity well which allows them to have the whole event horizon thing. Magnetars are close but they aren't quite that fierce. They still generate enough centripetal forces to keep them from collapsing into a singularity, therefore no event horizon. I don't think they have the tidal energy to generate the kind of dynamic forces required for a black hole type accretion disk. At least not one anywhere near that strong. A magnetar might well have rings and satellites but I suspect the system would be more like Saturn on steroids than a black hole. It's all a balancing act anyway. In a black hole gravity wins on all counts. In magnetars, neutron stars, and super giant stars gravity still hasn't quite won the battle, yet.
I'm happy to watch the occasional advert on TH-cam to support creators. I'm not happy to have two pop-up advert dialogues that I have to close and a video advert all within less than 8 minutes of a 12 minute video.
Madonna Offect: The phenomenon of American narrators speaking in a false British dialect is so mind blowing I can't hear any of the amazing information presented in this staggeringly ridiculous way.
You're just now discovering what is an fallen angel's prison cell. Magnetars have everything built into them to contain what it swallows. If any prison break is attempted, the physical characteristics of the cell will destroy you.
We will never know how the universe works; we will be very lucky if someday we even know how we work -- and what part we really play in the circumstances around us.
Wow, I see a lot of people not pleased with the narration in the comments. I find that rather interesting, because yes, the robotic monotone voice probably wouldn't be the route I would take, but I found it oddly satisfying to watch with this particular video. Now, I'm from Texas though, and hard of hearing So maybe I just appreciated the clear speech, and emphasized dramatics because otherwise I wouldn't be able to hear it. And now that everyone has a mask, I REALLY can't understand folks. That's a different story though. I liked the video..

In summary, the encounter between a copper sphere the size of the Sun and a magnetar would be catastrophic for the copper object. It would be subject to extreme electromagnetic forces, heating, vaporization, gravitational tidal effects, and potentially even powerful radiation bursts.
@5:46 understatement of the century!
A golf ball dropped from 1 meter above the surface or a neutron star would hit it half a millionth of a second later, at a large fraction of the speed of light and with a force greater than all the thermonuclear weapons in the world combined.
So yes, "A human would be torn to bits in a matter of seconds",... and then some!
The tidal gravitational force would tear a body up even before impact.

I love it when we begin sentences with "despite our incredible technological advances..." and follow with the latest gaping hole in our understanding. I have a friend who happens to be a world-renowned physicist. When I told him 10 years ago about a popular book called "The End of Science," wherein the author claimed that we had pretty much worked out 99% of what there is to know about the universe, he laughed so hard that tears were streaming down his face and he couldn't even speak for a good 5 minutes. When he finally got ahold of himself again, he explained to me that the situation was exactly the opposite. Why do we always think we are so smart, so advanced? Just think about the barbaric methods that were the state of the art in medicine 100 or even 50 years ago. We are still just crawling out of our caves. We still don't even have a Unified Field Theory. We don't even really understand gravity yet. And don't even get me started on our barbarous societal arrangements (I mean, just consider America, the richest country in the history of the world, and the way it treats the vast majority of its citizens...)
It's not the richest in the world, it has the highest GDP but there are many many countries where your average person is far wealthier.
That scientist's name? Albert einsteinus.
What a BS.
you're right - many of my non-scientific friends dont seem to believe this - "We don't even really understand gravity yet" - but its perfectly true and TBH we dont even really understand electricity either - just because we use it does not mean that we understand it. As far as "understanding" anything goes, it seems that the harder you look the more you find - eg the many many forms of subatomic particles

"Which in essence is trillions of times that of the electromagnetic radiation on the earth". But isn't electromagnetic radiation in reference to, you know, the scale from radio waves to gamma rays? With visible light somewhere in the middle? That has nothing to do with neutron stars having a 10*13 Tesla magnetic field strength.... but okay, continue... hahaha
CJ White: That's what I love about TH-cam. Nothing should be taken too seriously but only thought provoking and good entertainment. You obviously are a learned gentleman and expect accuracy in scientific explanations.
the way you put the information is unbelievable, despite I know most of those pieces of information I watched the entire video, good work and good choice for the music too.
I once traveled to a magnetar and stopped it’s rotation with my bare hand and de-magnetized it with a Hello Kitty refrigerator magnet.
A collision between a blackhole and a magnetar would be magnificent to hear and see.
Kosmo, don't worry about the negative comments about your 'dramatic' style of presentation. you are a channel that i would put side by side with isaac arthur. It may well irk people already steeped in physics, but your delivery makes the subject matter very accessible to a larger audience. and it is necessary to have showmanship in voice over presentation.The mindblowing facts are usually lost if delivered in monotone voice, without appropriate pauses after significant statements.a channel has to be both entertaining and educational. Kosmo provides both. similar to isaac arthur, except the latter is more futurism e.g. detailed recreation of humanities first mass interstellar 'ark' to search for and colonise a planet in another star system when earth and all inner planets becomes uninhabitable with an expanding sun in about a billion years. His videos are truly epic and long. you do shorter snappier ones. and you are a very new channel in comparison. Also appreciate your voice/accent like isaac arthur rather than all those whiny american accents of millennials.
Many non university educated people think science boring, because of a poor high school teaching experience.so dramatic entertaining presentation/teaching overcomes that. and science is really THE most important and relevant academic subject of them all, which includes its incorporation of many mathematical theorems. as for myself after gaining my undergraduate degree in the American studies school of my university, later in life cultivated a thirst for scientific knowledge about the universe, especially cosmology-astrophysics, experimental physics, planetary science, exo-chemistry/biology and marine biology. and took my physics BSc undergrad with the open university, with one free-choice module each semester, allowing me to take minors in my specific subjects of interest, as listed above. ninety percent from home, and ten percent was science field trips. most of the population of first world countries even are relatively scientifically illiterate-they never pick up science after high school again. in U.K it's worse as we leave high school at sixteen years old, with sixth form/college two fill the two year gap until university being purely voluntarily. . That is we can finish our education at sixteen, and usually only those aiming for university take their A levels at a sixth form/further education college. that means every American is receiving two more academic years of science curriculum physic chemistry,biology, and subcategories of physical geography like climate and weather science and geology. keep up the good content.

Why are magnetars and neutron stars always portrayed as spinning spheres? Wouldn't something that massive and spinning that fast be more of a disk or a even a ring? And if the gravity well was strong enough to force it into a sphere, despite internal pressures and centrifugal forces, wouldn't it also be strong enough to collapse it into a black hole? And if it were in fact a ring, what would be the nature of space/time at the center of the ring?
Just a musing from a high school drop out.
It's because there are facters that they don't even know exist.
The most geometrically stable object is a sphere. A disc wouldn't support 3 directions of radially inward geodesics.
Totally true, for a stationery object. But don’t these things tend to spin, I mean like really fast, on a cosmic level type fast? The centrifugal forces of a spinning object that massive must be mind boggling. And as anyone knows, inertia is the one force that can challenge gravity on any level, any time, anywhere. So, just how fast can they spin?
@@ralphscholz9533 there's a pulsar in the Sagittarius constellation that spins about 700 times a second. The disc that you talk about is called an accretion disc, it appears as a disc to us, the observer due to the immense bending of light from behind the spherical blackhole. There's a fun video of veritaisum that explains it.
@@nawdudegaming9368 Yea, I know about the accretion disk. But that's for black holes, they have a much deeper gravity well which allows them to have the whole event horizon thing. Magnetars are close but they aren't quite that fierce. They still generate enough centripetal forces to keep them from collapsing into a singularity, therefore no event horizon. I don't think they have the tidal energy to generate the kind of dynamic forces required for a black hole type accretion disk. At least not one anywhere near that strong. A magnetar might well have rings and satellites but I suspect the system would be more like Saturn on steroids than a black hole.
It's all a balancing act anyway. In a black hole gravity wins on all counts. In magnetars, neutron stars, and super giant stars gravity still hasn't quite won the battle, yet.
This is the one star I wish had a place on Hollywood Boulevard. You wouldn't even see it coming.

So _this_ is what Kurt Cobain was talking about in Heart-Shaped Box: magnet tar pit trap.
So is the closest one 9,000 light years away (5:18) or 13,000 light years away (8:24)? We should probably figure that out for sure...

The 9000 ly one is the closest AXP, the 13000 ly one is the closest SGP

You're just now discovering what is an fallen angel's prison cell. Magnetars have everything built into them to contain what it swallows. If any prison break is attempted, the physical characteristics of the cell will destroy you.
