    Neutron stars are one of the most extreme and violent things in the universe. Giant atomic nuclei, only a few kilometers in diameter but as massive as stars. And they owe their existence to the death of something majestic.

      Yogg I may have my information mixed up here, but when the universe first started, stars were both born quickly and died quickly due to the universe being much more hot from the Big Bang. So, it didn’t take stars nearly as long to die when the universe was first created.

      What are the chances we could exhaust smaller stars to the point of creating Kilonovas to create personal galaxies? Or maybe another planet that could sustain life? Plant it like tree lol?

    How do neutron stars die, if they don‘t collide with another neutron stars, will they just burn out and evaporate over billions of years or will they collapse into a black hole after a while ?

  • Максим Соколов

    Aren't gold and other heavy elements created in supernovas? Because of this fast falling of outer layers on the core and bouncing back creates more extreme conditions than in the iron core.

    4:32 what if pasa was created in order to have access to the strongest material in the universe?

  • Максим Соколов

    I have some questions.
    For example, is the matter in a neutron star stable under normal conditions?
    Or it requires huge pressure and nuclear matter decays into neutrons, which create protons and electrons and finally form usual matter?

    And make a bundle with all posters with any sale off to buy everything? Just for Christmas
