you still have mistakes, the car wheel analogy 4:45 os totally irrelevant, you need to specify the wheel diameter to get that speed number, this is not good.
It's to give an order of magnitude. Car wheels are usually of very similar sizes, you'll never have a wheel of 1 centimeter or 10 meters. In astrophysics it's always useful to give orders of magnitude to get an idea of how big / how fast something is, even though the calculation is just an approximation it doesn't really matter

@@alisaied4958 I had the same initial thought, but it has 0 bearing on the explanation, so I discarded it... If you want you can figure out the diameter of the wheel independently, but its inconsequential to the conclusion

You can change the world with the amount of simple knowledge you give. I’m not a robot as well! I just want to say: thank you so much for these videos. Do not stop making them! Thanks again!!
I was following this channel for mostly things like understanding quantum physics and relativity, but It covers topics like outer space too, which I love. So glad I found this content. Keep up the great work!
Some think Science is a sterile subject, but videos like this send a chill down my spine, as deeply hidden truths about the Universe we live in are revealed, one layer at a time, through the sum total of human scientific endeavor, that brought us to this moment in time, where such deep knowledge can be shared to all who would just stop and take a moment, to listen and learn. Thanks ScienceClic, channels like this, present the good side of an online and connected world.
I alwais think that all of the laws of physics are the way for the univers to be conscious and not collapse on itself , making us able to experience reality and be conscious about it
It’s what made me realize there is no way it’s just an accident. There had to be someone who made it all. He answered me shortly after. God is real, and He reveals Himself as He chooses. He revealed Himself to Abraham and all of his descendants. Now we look His creation in the face and have the gall to say “what God?” To me it’s not too wild a stretch to say that there is an intelligent creator God, Holy in nature so we cannot be in His presence without dying because of our filthy selfish natures. Yet he decided not to leave us to that state but reach out to us. To become flesh and die the most painful death imaginable just to save anyone who believes and abides in Him. Every action has an equal opposite reaction. You sin, you pay the price. So the price had to be paid. He paid it so we can live. It’s not such a stretch to me, that the one who is Himself morality is the one who dictates what is and is not good. The study of science has often been pioneered by believers striving to know more of the nature of God. It’s not a stretch that the humans He made in His image (relational intelligent beings) would want to know more about Him, given the chance. Thanks to anyone who read this.

A concept is said to be well understood when you can "visualize" it. The animations in this video definitely help understand the concept very well. Thank you. Please keep making such videos!
At around 10:00, you speak about the effects such a strong magnetic field has, but it remains confusing, if you think this is a worthy topic, what would you think about a video that explains the interractions of the electro magnetic field with spacetime? How are the two related, how do they interract, and how do strong ammounts of distubances in those fields affect the other (ie: do large ammount of currents or magnetic fields have an effect on spacetime? Do strong ammount of gravity have an effect on the EMfield or electron field?) This would make for a very intresting topic on the fundamental workings of the universe
@@Meowface. Correct me if I'm wrong but aren't magnetic fields made out of electrons? And electrons do have mass, so I don't see how they can't alter space time
I have the same question, I was wondering if space time has properties which has tiny magnetics with north and south poles (could be higgs boson), the connection within those particles are spread evenly and creates elasticity and pressure properties in space time which creates gravity by squeezing the subatomic particles to one another, in the case of magic field, I think the star twist these particles creating a tornado, aligning these particles in one direction creating a giant magic field.
The particles that generates gravity and magnetic field are the same, but the effects caused by different forces are caused by the properties of space time in large scale.
@@loljptrollergami7325 he is right, the star is very dense and the rotation is so fast that space time can't pass straight through it, I can tell because the differences of the axkes within rotation and magnetic field.
It is just so fascinating to know that pulsars can speed up in almost an instant because the surface falls down a few MICROMETERS because of the lag of centrifugal force.
It's just conservation of angular momentum. As the mass shifts closer to the center of the pulsar it's moment of inertia decreases, therefore it must spin faster to conserve angular momentum.
@@ozAqVvhhNue a good way of understanding what he's saying is to sit in a spinning chair. Hold equal weights in your hands and start spinning. Hold the weights out away from you as far as you can, and then pull them into your body. You'll notice the speed at which you rotate increases based on the distance the weight is from your centre. You don't have to use weights but it'll demonstrate the conservation of angular momentum better.
I love this channel. We researched, explained in a plain language we can all understand and excellent graphics. This is perfect for a lay person with an interest in astronomy like myself. Great stuff!
12:15 Man, there is just so much incredibly intresting stuff in that video So the very fast rotation speeds don't just come from the initial angular momentum the star had before it went supernova, but from a secondary star? This is such a fascinating effect, if you take the baricenter of the system as a refernce frame, then the star, less dense, has matter with a much higher potential energy than the pulsar does, so when the mass of the star somehow ends up absorbed by the neutron star, it has the same effect as an ice skater pulling their arms together, just on an insane level because of the density of the neutron star And therefore, the entire kinetic energy of the orbitting pair (given the star ends up colliding with the neutron star), is entirely converted into an insane ammount of angular momentum, it's literally the spin that was in the orbit of the matter in the star that becomes the spin of the pulsar But this also raises a question, if a neutron star is formed, then later collides with a main sequence star in this manner, chances are the collision won't happen in the original spin axis of the star, so what happens then? Does the star have the "rigidity" to somehow change it's entire spin axis at the mergure of the two, or can you have a scenario where the core of a neutron star, formed from it's original star, has a different axis of rotation than it's outer layer, formed from absorbed matter that came from another star?

It's a phenomenon called vacuum birefringence, due to polarization of the quantum vacuum under strong magnetic fields. This is still little known but it has been measured experimentally to some extent around the neutron star RXJ1856.5-3754
"This channel gives proper idea about things we understand only vaguely. " Yep, exactly My background is not in astrophysics, but I am sure that anyone would get an even better intuitive understanding of these phenomena than someone studying the physics without this visual aid would, I hope physics teachers that teach those subjects start showing those videos to their students, only good can come out of a greater understanding of physical pheonomena in general, especially from the future experts themselves
Your videos contain plenty of information and answer some questions that I had for a long time and the animation just beautifully completes it, making it easier to understand :)
If a star is created by the exploded guts of a star before, and assuming it has not used 100% of said gut matter, does that mean stars will eventually just get smaller and smaller? Never being able to be bigger or as big as the star it was born from?
As the universe ages there will be less and less hydrogen available for new stars to form, thus more than likely yes, there will be less and less massive stars and eventually no larger stars will be able to form at all. This is already happening; over 60% of all stars in the universe are red dwarfs.
This is where the funding of basic research is vital. There is NO useless scientific information. Basically, the scientist makes a theory based on basic principles, and then the researchers try to find phenomena that match that theory. At the same time, other researchers are trying to find other phenomena that go against the original theory. When you have more A than B, then you have a successful theory.
8:42 Degenerate matter? I don't see why you have to get personal when discussing astronomy. And, frankly, their lifestyle is none of your business. So judgmental.
you should get rid of that white bar at the top, it's a distraction from the amazing animations. there's really no need for it. respect for the effort you put into these ;)
Honestly I was always jealous of people who are younger and yet more successful than me; and I think you take the cake on that. Obtained a master's degree at a prestigious college (not to mention achieving Summa cum laude on all diplomas) and doing so many stuff like astrophysics, graphics and animation, music, web development.... I hate you. Keep up the great work! This channel is only just beginning with it's soon to be millions of subscribers! My respects man!
It is a mistake to say that at the end of a star's life nothing is acting against the collapsing force of gravity so it collapses. There is a compression force of the materials resisting gravity, just like how earth and other planets are stable, but this force is not big enough compared to gravity. Therefore the star collapses
At 5:18 you say that the difference in pull between the person's head and feet are 100,000,000 times Earth's gravity. If g=9.8 m/s^2, then that difference is 980,000,000 m/s^2. If the speed of light is approximately 300,000,000 m/s, then wouldn't this mean that the feel would accelerate away from the head at a rate greater than 3 times the speed of light? I feel like something is off here, maybe OP is off by an order of magnitude.
VERY IMPRESSIVE!👍 Only astronomical magazines have given me such an in depth, yet a very understandable narrative on pulsars. Oh, and such a great and responsible use of CGI imagery.
I thought pulsars emits EM radiation because of contraction/expansion. I learned something new. Thanks! Btw, visuals are so good. Do you use after effects?
just wanna remind you have amazing this channel is and how i just cant get enough of it!! i hoe one day your content will be in 4k. i know the diagrams and such doesnt really need it but still to have such a sharp image would be fantastic! Thank you so much for your work and love for yall things science..
Einstein's general relativity shows us that massive objects distort space and time aka spacetime. Gravity is perceived because of the gradient in spacetime. There are great videos that explain this much better. Follow your curiosity.
Yes it's a phenomenon called vacuum birefringence, due to polarization of the quantum vacuum under strong magnetic fields. I think if you search for the neutron star RXJ1856.5-3754 you should find more details about this, it's the neutron star around which scientists think they measured this effect
11:00 OHHHH, so that is how they generate the beams, since the disk is on a plane, and the magnetic field has a different plane with the same center that rotates, the circular rotation of the field create forces normal and antinormal to the plane of the accretion disk, this pulls up or down a part of the inner ring, and then the continuous rotation of the magnetic field keeps increasing those small differences, the particle that end up forming the beam are accelerated in a sort of spiral pattern, and they reach such incredible speeds because of the strengh of the magnetic field Extremely intresting, I had never seen the mechanism behind the particle beams/torches explained anywhere before That raises a few question, it would mean that the strengh of the beam depends on 1, the ammount of matter on the inner disk of a neutron star, 2, the strengh of it's magnetic field, 3, on it's inclination compared to the plane of the disk, and 4, on it's rotation speed, does anyone know if there has been studies either looking at a bunch of pulsars do guess those parameters by the strengh of their beams, or alternatively a study on a model that calculates precisely a model for the strengh of a beam depending on all the parameters? Also I remember reading a study that found out that neutron stars did not have a symetrical magnetic field as was expected, would that mean that a lot of pulsars have a single beam? If so, it could change our understanding of the ammount of pulsars in the universe, if most of them just have a beam on one side if we expected them to have a beam on both, it would mean there are a lot more pulsars than we thought
What I said was maybe confusing, so grab a long straight stick, and put a hoop/ring around it, and then hold the stick vertically, and star spinning it in small circles, you will see that the ring ends up being accelerated, slowly at first, but then faster and faster until it shoots out of the top and hits the cieling, this is the exact same thing that creates the beams of pulsars, except instead of a stick, you have a magnetic field, and instead of a ring you have gas In this example the shape of the ring isn't important, it just has to be a ring to tie it to the stick and make sure it can't jump out, the same way the particles are tied to the magnetic field
The visuals in this one stand out to me. They make what is being spoken extremely vivid. The experience of watching/listening to this is how I imagine an omniscient god might see the universe.
How can a proton merge with electron to form a neutron? Protons and electrons are fundamentally different: electrons are elementary leptons, while protons are composite particles made of Up, Up, and Down quarks. How can those two merge to produce a composite particle made of Up, Down, and Down quarks?
Good question, the transformation is the following : u + e -> d + v up quark + electron -> down quark + neutrino you have one quark and one lepton on both sides, and -1/3 charge on both sides so things check out
Have a ton of questions ... how does a neutron star have an atmosphere? What's the atmosphere made of ? Why does a star 10 times the mass of the sun turn into a neutron star ? What about fusing carbon or oxygen etc? How does it run out of fuel? How can a neutron star contain free atoms if the gravity is so strong? You mentioned that the mass of Pluto put squeezed to the size of a house would be the same density as a neutron star, if so then your big is this house? It's a very vague measurement . Would really appreciate it if you could go a bit more indepth about this. Awesome video. Thanks. Keep it coming. All the best. 👍
It is not actually, read your sources which explain what the verse is talking about. The surah is called At-Tariq because the star comes at night, like a man from the Tariq family: Ibn Kathir says ""The star has been named Tariq because it is ONLY SEEN AT NIGHT AND IT IS HIDDEN DURING THE DAY.'' His view is supported by what has been mentioned in the AUTHENTIC Hadith that prohibits a man to come to his family Taruq." Pulsars don't come/are not visible at night only - they are visible day and night. If you read the other tafsir scholars they point to objects visible at night, why? Also, why doesn't a single Islamic scholar mention that the object is making knocking sounds, and the objects they list most certainly do not make any. Don't these great scholars understand the meaning of the Quran and its clear Arabic? Ibn Abbas: the bright, piercing star; this refers to the planet Saturn which shines at night and DISAPPEARS during the day. al-Jalalayn: meaning [the constellation] Pleiades; al-Wahidi: This is a meteor that was thrown and it is one of the signs of Allah As for the science, pulsars DO NOT make any sounds. What you hear in these videos is the transformation of the intensity of the radio beam into sound (data sonificaton) but the beam itself makes no noise and if you were in the rotating frame of the pulsar the intensity would be constant. The stars were named pulsars because of the pulsation of the light intensity, not because they made sound pulses. You can convert the light from a lighthouse into sound, you can convert colour intensity into sound - does that mean that they make a sound?
This channel has a unique way of presenting science in simple way with addition of something extra making me learn something new where I do not see such information on other channels. However what I love is the choice of music which is consistent across the channel, at first it starts as relaxing music and then suddenly gets serious when it gets to main content. I subscribed.

As the universe ages there will be less and less hydrogen available for new stars to form, thus more than likely yes, there will be less and less massive stars and eventually no larger stars will be able to form at all. This is already happening; over 60% of all stars in the universe are red dwarfs.
it blows my mind how people even understand how this stuff works.
This is where the funding of basic research is vital. There is NO useless scientific information. Basically, the scientist makes a theory based on basic principles, and then the researchers try to find phenomena that match that theory. At the same time, other researchers are trying to find other phenomena that go against the original theory. When you have more A than B, then you have a successful theory.
8:42 Degenerate matter? I don't see why you have to get personal when discussing astronomy. And, frankly, their lifestyle is none of your business. So judgmental.
Always great videos
God I love this channel
The animations and the explanations are great. Thank you!
That 1 dislike came from a medium sized star
You are going to have millions of subscribers one day.
One question. Why this extremly dense pressured matter did not became normaly pressured again after this supernova explosion.
you should get rid of that white bar at the top, it's a distraction from the amazing animations. there's really no need for it. respect for the effort you put into these ;)
Honestly I was always jealous of people who are younger and yet more successful than me; and I think you take the cake on that. Obtained a master's degree at a prestigious college (not to mention achieving Summa cum laude on all diplomas) and doing so many stuff like astrophysics, graphics and animation, music, web development.... I hate you.
Keep up the great work! This channel is only just beginning with it's soon to be millions of subscribers! My respects man!
Notif squad
God tier quality again. I'm so impressed with the animations and want to learn them. May you get your own documentary one day!
Are the nucleons in the star held together in pasta form strictly due to the Strong interactions?
Yes and, as we know, this is much stronger than the electromagnetic force.
God nothing is more fascinating than space, excellent video my friend
Can somebody tell me how he make those type of visualization and animation 💔
It is a mistake to say that at the end of a star's life nothing is acting against the collapsing force of gravity so it collapses. There is a compression force of the materials resisting gravity, just like how earth and other planets are stable, but this force is not big enough compared to gravity. Therefore the star collapses
Very nice work brother. I have now cleared my doubts about neutron stars, magnetar and pulsar. Thank you very much.
This is exactly what I was looking for. Just perfect.
Absolutely love the content you are making... can't appreciate your hard work enough... you're so cool man.
“Allowing us to observe its rear” 💀💀😁😁
My favourite channel. Please make a detailed video on Maxwell's demon.
At 5:18 you say that the difference in pull between the person's head and feet are 100,000,000 times Earth's gravity. If g=9.8 m/s^2, then that difference is 980,000,000 m/s^2. If the speed of light is approximately 300,000,000 m/s, then wouldn't this mean that the feel would accelerate away from the head at a rate greater than 3 times the speed of light? I feel like something is off here, maybe OP is off by an order of magnitude.
how electric energy comes from it's surrounding fields
VERY IMPRESSIVE!👍
Only astronomical magazines have given me such an in depth, yet a very understandable narrative on pulsars.
Oh, and such a great and responsible use of CGI imagery.
I thought pulsars emits EM radiation because of contraction/expansion. I learned something new. Thanks!
Btw, visuals are so good. Do you use after effects?
Thanks ! Yes I use After Effects :)
just wanna remind you have amazing this channel is and how i just cant get enough of it!! i hoe one day your content will be in 4k. i know the diagrams and such doesnt really need it but still to have such a sharp image would be fantastic! Thank you so much for your work and love for yall things science..
Really good explanation graphics everything just wow
Amazing channel! Here when 100k+ subs. It will and should be millions+
Stupendous!
Where does the outside gravity come from
Einstein's general relativity shows us that massive objects distort space and time aka spacetime. Gravity is perceived because of the gradient in spacetime.
There are great videos that explain this much better. Follow your curiosity.
here you mentioned the effect a very strong magnetic field has on vacuum- what is the name of this phenomenon and where can I read mode about it.
Yes it's a phenomenon called vacuum birefringence, due to polarization of the quantum vacuum under strong magnetic fields. I think if you search for the neutron star RXJ1856.5-3754 you should find more details about this, it's the neutron star around which scientists think they measured this effect
Thank you for posting this :)
11:00 OHHHH, so that is how they generate the beams, since the disk is on a plane, and the magnetic field has a different plane with the same center that rotates, the circular rotation of the field create forces normal and antinormal to the plane of the accretion disk, this pulls up or down a part of the inner ring, and then the continuous rotation of the magnetic field keeps increasing those small differences, the particle that end up forming the beam are accelerated in a sort of spiral pattern, and they reach such incredible speeds because of the strengh of the magnetic field
Extremely intresting, I had never seen the mechanism behind the particle beams/torches explained anywhere before
That raises a few question, it would mean that the strengh of the beam depends on 1, the ammount of matter on the inner disk of a neutron star, 2, the strengh of it's magnetic field, 3, on it's inclination compared to the plane of the disk, and 4, on it's rotation speed, does anyone know if there has been studies either looking at a bunch of pulsars do guess those parameters by the strengh of their beams, or alternatively a study on a model that calculates precisely a model for the strengh of a beam depending on all the parameters?
Also I remember reading a study that found out that neutron stars did not have a symetrical magnetic field as was expected, would that mean that a lot of pulsars have a single beam? If so, it could change our understanding of the ammount of pulsars in the universe, if most of them just have a beam on one side if we expected them to have a beam on both, it would mean there are a lot more pulsars than we thought
What I said was maybe confusing, so grab a long straight stick, and put a hoop/ring around it, and then hold the stick vertically, and star spinning it in small circles, you will see that the ring ends up being accelerated, slowly at first, but then faster and faster until it shoots out of the top and hits the cieling, this is the exact same thing that creates the beams of pulsars, except instead of a stick, you have a magnetic field, and instead of a ring you have gas
In this example the shape of the ring isn't important, it just has to be a ring to tie it to the stick and make sure it can't jump out, the same way the particles are tied to the magnetic field
Very user-friendly presentation. Nicely done.
I SO love this channel! I have learned SO from this channel! Keep up the amazing work guys!
You should do a collaboration video with one of the bigger science youtube channels. This content is way to good to have this few views
whats the revolution maxium for pulsar before its gravity cannot hold it together leading it to go apart in dics shape?
Well information. Good information.
The visuals in this one stand out to me. They make what is being spoken extremely vivid.
The experience of watching/listening to this is how I imagine an omniscient god might see the universe.
So good!!! Excelent!
These things are utterly mind-boggling, that such extreme objects exist...
one more!!!!!!!!!!!!!!!!!!
Mathematics of QFT !!!
much needed video.amazing
me empecé a reir bastante fuerte cuando empezó a hablar de como los cientificos los clasificaban como pastas, el ñoqui me tomó por sorpresa
How can a proton merge with electron to form a neutron? Protons and electrons are fundamentally different: electrons are elementary leptons, while protons are composite particles made of Up, Up, and Down quarks. How can those two merge to produce a composite particle made of Up, Down, and Down quarks?
Good question, the transformation is the following : u + e -> d + v
up quark + electron -> down quark + neutrino
you have one quark and one lepton on both sides, and -1/3 charge on both sides so things check out
Today I learned neutron stars and black holes are very similar.
Just amazing!
Not a single muslim or christ in the comments...
How good can a day end🥰
Wow, very nice presentation.
Have a ton of questions ...
how does a neutron star have an atmosphere? What's the atmosphere made of ?
Why does a star 10 times the mass of the sun turn into a neutron star ? What about fusing carbon or oxygen etc? How does it run out of fuel? How can a neutron star contain free atoms if the gravity is so strong? You mentioned that the mass of Pluto put squeezed to the size of a house would be the same density as a neutron star, if so then your big is this house? It's a very vague measurement . Would really appreciate it if you could go a bit more indepth about this. Awesome video. Thanks. Keep it coming. All the best. 👍
"What you wanna eat dude"
"Pasta"
"Okay." **Breaks up a pulsar star**
Another wonderful video. Thankyou
Great channel. One of my favs.
It is mentioned in Quran, in surah Al Tariq (the knocker of the door) , it is a piercing start (the sound like knocking a door)
It is not actually, read your sources which explain what the verse is talking about. The surah is called At-Tariq because the star comes at night, like a man from the Tariq family: Ibn Kathir says ""The star has been named Tariq because it is ONLY SEEN AT NIGHT AND IT IS HIDDEN DURING THE DAY.'' His view is supported by what has been mentioned in the AUTHENTIC Hadith that prohibits a man to come to his family Taruq."
Pulsars don't come/are not visible at night only - they are visible day and night. If you read the other tafsir scholars they point to objects visible at night, why? Also, why doesn't a single Islamic scholar mention that the object is making knocking sounds, and the objects they list most certainly do not make any. Don't these great scholars understand the meaning of the Quran and its clear Arabic?
Ibn Abbas: the bright, piercing star; this refers to the planet Saturn which shines at night and DISAPPEARS during the day.
al-Jalalayn: meaning [the constellation] Pleiades;
al-Wahidi: This is a meteor that was thrown and it is one of the signs of Allah
As for the science, pulsars DO NOT make any sounds. What you hear in these videos is the transformation of the intensity of the radio beam into sound (data sonificaton) but the beam itself makes no noise and if you were in the rotating frame of the pulsar the intensity would be constant. The stars were named pulsars because of the pulsation of the light intensity, not because they made sound pulses. You can convert the light from a lighthouse into sound, you can convert colour intensity into sound - does that mean that they make a sound?
Neutron stars are black holes lite, and are less scary just because they are not black.
That’s a beautiful channel, my favorite as of today, and that supernova! Masterpiece
This channel has a unique way of presenting science in simple way with addition of something extra making me learn something new where I do not see such information on other channels. However what I love is the choice of music which is consistent across the channel, at first it starts as relaxing music and then suddenly gets serious when it gets to main content. I subscribed.
