About once every century, a massive star somewhere in our galaxy runs out of fuel. No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova. The death of that star is the birth of a neutron star: one of the densest known objects in the universe. David Lunney explores what, exactly, a neutron star is.

@silverlight4977 2 года назад

You will be surprised to know that it was proved in theory first. Many things surrounding the the celestial bodies are in theory as of now. Even Neptune was discovered when someone said, there will be a planet at this point in the night sky

@@silverlight4977 yes Neptune was the only planet discovered using maths ......... First Uranus was see. In the telescope but the telescope was not powerful enough to see Neptune but as Uranus was observed and it was seen that Uranus's orbit was affected by Neptune's gravity and like that it was assumed that there is a celestial body present even though it was not seen

@dx5soundlabs939 2 года назад

Might be a sign that this is a whole lot of conjecture and not necessarily anywhere close to proven

@alexalford7874 2 года назад

@@dx5soundlabs939 I wouldn’t say so, I think that’s just an argument from absurdity. A lot of these understands are drawn from how we understand other areas of physics. We have a pretty firm grip on gravity, and so one way we could determine it’s mass is by seeing how the object may effect objects near it. We have a very firm grip on orbital mechanics because a lot of that relies on classical mechanics. We may know what the object is made of or what a large portion of it is made of by using spectral analysis, a process used by chemists that can determine the chemical makeup of something by using the light emitted from it. We don’t know for a fact that neutron stars are made of just neutrons because that’s a hypothetical substance, but it’s heavily suspected because we know that with how dense it is there should be so much force exerted that it beats electron degeneracy pressure that is used to keep two electrons of the same spin from occupying the same space, and so clearly the pressure was beaten so it must be some other state of matter that exists. There’s stuff we definitely don’t know, but a lot of it isn’t just mere “conjecture”, the methods they use to determine these things are very sophisticated and based on applications back at home. Also, I wouldn’t really use the word “proven”. We talk about “proof” when we’re in the world of mathematics.

@yunoadirangga8155 3 года назад

Respect is good. But don't be too awestruck. Einstein is a theorist: he predicted. To prove him right or wrong, it still require the works of experimentalists and some measure of technology. So the glory is not Einstein's alone. There are theorists living today as well. Have you heard string theory? It's still unproven. Those theorists' glory, if they ever come, won't be due to themselves alone.

You said that about once in century a massive star in our galaxy runs out of fuel and it ends up with an explosion that leaves literally a neutron star. That means we get a neautron star once in a century right? And for its beaming and spinning it appears to blink when viewed from earth. But we see couple of those blinking stars at a time. Is it for their ages? I mean does it mean some of them are older that stay with the new ones?

I see Neil DeGrass Tyson talking about how he doesn’t exist and I actually like him but I think that he is wrong. As an astrophysicist, he should know that there is way to much out there that we can’t even begin to understand, so he can’t dismiss the idea of God because he can’t explain it or because our modern “science” can’t understand it!

@DegreesOfThree 5 лет назад

@@genroynoisis6980 Redshift is when light appears to be of a longer wavelength, typically because it is moving away from the observer. However, they've found stars within the same galaxy that have radically different redshifts, which indicates that redshift may have other causes we don't fully understand. Since all distant galaxies appear to be highly redshifted, astronomers have assumed that the universe must be expanding, but this is a very flimsy assumption.

Scientists have never measured a sample of a neutron star, they're just making their best guess based on a faulty assumption about gravity. They think gravity is purely a function of mass, therefore a neutron star must be insanely dense even though such a density is patently absurd and has never been demonstrated to actually exist.
