NEUTRON STAR - The Most INSANE Object in the Universe

Imagine a teaspoon of matter scooped from the surface of a dead star. It weighs about a billion tons - more than a medium-sized mountain. Such matter really exists, and there is quite a lot of it in the Universe: it is packed into balls about twenty kilometers across, the size of a large city, each one heavier than our Sun. These are neutron stars - the densest objects that can still be called objects, because the next step in density is already a black hole. In this film we break down everything: how a massive star dies, why the iron in its core becomes a death sentence, and how a core the size of a planet collapses in on itself in a fraction of a second at a quarter of the speed of light. Why electrons are crushed into protons. Why the heavier a neutron star is, the smaller it gets. What "nuclear pasta" is, and the superfluid liquid deep inside that cannot be produced in any laboratory in the world. Separately - the story of the discovery of pulsars, when astronomers seriously discussed the idea of a signal from an alien civilization and named the source "Little Green Men". Magnetars with a field a thousand trillion times stronger than Earth's, and starquakes that release more energy in a fraction of a second than the Sun radiates in ten thousand years. Neutron star projectiles racing through the Galaxy. A diamond planet next to a pulsar. And most importantly - the kilonova: a collision of two dead stars in which platinum, uranium and gold are born. The metal in your ring was forged exactly there, long before the Sun appeared.
