@@r.a.tackey3230 you are just a kid you just do not have enough knowledge to say this this science is very deep and there are many proves for this infact there visual proof of this through a telescope.If you want proof then study astrophysics lol but dont say that they have no proof without knowing whether there is any proof of what you are saying In physics most of things are not proved, rather a hypothesis is presented and it is valid until someone disproves it. So just shut up and go to bed.
I remember as a kid I had that one solar system book and it always fascinated me. This video is well done, never really understand in school how the stars are born and how they die.
I used this amazing video on my physics prezentation since it covered the whole point perfectly and i got an A! Beautiful video and everything is very nicely explained. Good job and thank you for sharing your knowledge!😊
This 5mins is most worth while 5mins spends of my life. So eloquently this video tells everything about the life of star and without missing anything. Thanks

In school, we have to create a poster or presentation on a certain space topic and my topic is the life cycle of stars and this video was extremely helpful.
the "dost", lol. cracks me up. excellent video. I like it. Very clear and concise presented information. Thanks to this video, I think i understand what a black hole is now. It is a state where gravity that pushes inward is no longer balanced by fusion that pushes outwards, then particles get packed closer and closer together with no outward force to counter balance that tendency anymore. Eventually the neutrons, electrons and protons cannot move anymore and atoms become invisible as emitting light requires the motion of particles. It is interesting that nature runs out of heavier elements to fuse. This state of black hole seems inextricable. It seems the universe will form more and more black holes until every star has become a black hole. I wonder how two black holes will interact with each other. They might counterbalance and allow matter to exit that state and create new stars but not without concentrating the universe closer around its center everytime. Eventually the universe becomes only one giant blackhole and create a big bang and a new universe if born and this forms a cycle. It could be that laws of physic remain the same only until a new big bang occurs then they could be replaced by new laws. Maybe arbitrary things like our 3 dimensional space will become 5 dimensional in the next big bang. It is interesting that the number 3 is the first number that is not followed by another prime number. Is the present table of periodic elements or atoms dependent on a 3 dimensional space ? Clearly molecules which are structures of atoms are 3 dimensional but atom themselves cannot be proved to be 3 dimensional, or can they ?
Can someone explain to me… I’m not very knowledgeable about this subject but find it fascinating. I was under the impression that our sun is in fact always gradually shrinking in size, not growing.
About two months ago, I watched a star go supernova. It was bright white with the usual blue, and red flashing that you normally see, then it was mainly pulsing red as it burned out.
I think you are wrong sir. The star burns all his hydrogen and Helium and it collapses until it becomes like a dwarf. The sun might be getting hotter, but I think it is actually cooling, collapsing. It sounds crazy, but what do you think of this guys
2012. So much has changed. Hopefully 2016 will bring some much needed reinterpretation of basic star science in light of the Kepler discoveries. If not? Then I guess tradition will hold out for a few more years.
I always wonder how we truly know these things since we haven't existed long enough to experience or even come close to studying this process. Seems very theoretical to me.

This is why I think it is not just simply a climate change. The sun is ageing. And there is nothing we can do about it but to live our lives beautifully as much as we can so as to not waste our precious existence.
Yes, eventually everything, even black holes will die off by a process called Hawking radiation. This will take a very long time though. Trillions of years.
yes, this is basically correct. The earliest stars formed after the proto universe cooled and the elements that we know formed were much larger than most stars forming today. This meant that many of them had shorter lifespans (the largest stars may live as little as 10 million years!) and went supernova. This helps spread various heavier elements such as carbon, nitrogen, oxygen etc, and when dust clouds reach enough critical mass (and gravity, since the 2 are linked to each other), a new star forms and the heavier elements become part of the early stellar dust cloud that surrounds proto stars and eventually form proto planets.
The heavier elements are produced during supernova explosions in reactions that go by the name r-process and s-process, though the latter also occurs in supergiant stars prior to them going supernova. Basically, these processes add neutrons to stable nuclei, buiding up massive, but very neutron-rich unstable nuclei. These then decay to stable, heavy nuclei. The s-process elements can occur for nuclie that have half-lives so long that even at low neutron fluxes they tend to capture a neutron before they decay, which can be the case in supergiant stars or during supernovae. The r-process nuclei are created during supernova explosions when the neutron flux is so high that even nuclei with short lifetimes tend to absorb extra neutrons before they can decay. Not much space here to give a detailed explanation, but if you want to know more just look up s-process and r-process on Wikipedia or in a book on stellar evolution - the book by D. Clayton is the classic one.
Tushar Bhagat Kevin McLin, got it right, but just as an FYI, its called "Neutron Capture". There are two types, those being the S-process (or Slow-Capture) , and R-process (Rapid Capture), that was already mentioned.
I think the energy source for a supernova star explosion is not as you say. The only thing powerful enough to cause this explosion is a matter/antimatter reaction. Therefor I say (when the center of the star gets hot enough) electrons are converted into antiprotons and annihilate with protons, and their combined mass is converted into heat which converts more electrons into antiprotons which annihilate with more protons in a supercritical nuclear reaction which causes the star to explode. Protons are actually antimatter particles, (being made from positrons in quasars) and antiprotons are matter particles. You don't have to agree with me of course. I don't want to argue. Just another opinion for you to consider.
Look up Gluons... They literally glue the neutron and protons together. For bigger nuclei more neutrons are needed than protons so elements heavier than iron decay down to iron through Beta, Alpha and Gamma radiation.

Do black holes then die? Do we know the "life cycle" of black holes?
Black holes I don't think will die
Possibly if two black holes meet and one is bigger than the other the smaller one could be ripped apart?
Black holes are weird.
Hector Maddock-Greene Yes. Yes they are
Yes, eventually everything, even black holes will die off by a process called Hawking radiation. This will take a very long time though. Trillions of years.
Hector Maddock-Greene THey combine
It was such a great help for my report tomorrow.
And I've been not understanding the teacher for 2 weeks and this is how easy it is ugh. That teacher doesn't know how to explain smh
So wait a star needs to die to make others star cuz a nebula is a dead star I'm I right ?

mrtheoden oh thank you !
10 yrs ago litrelly on my bday this video was posted 😭❤️✨
Their is no fusion after Fe. Then how were the elements with atomic number greater than Fe created?
The supernova explosion itself produces the heat and pressure needed to force fusion of elements heavier than iron.
