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.

      @Declan Sheridan Absolutely not If you were on the surface of a neutron star, with or without a spacesuit it doesn't even matter, you'd be very, very dead, from being crushed down by the gravity, vaporized by the heat, the reasons you'd be dead are so many they're hard to list all of them

    An interesting related topic is: primordial black holes These are theorized stellar sized black holes which could only have formed in the earliest moment of the universe. Essentially, the very early moments of the universe is theorized to have been a quark-gluon plasma and very minute differences in density would have caused the formation of stellar sized black holes. These have not yet been observed. The cores of neutron stars are also theorized to be quark-gluon plasma. Which is interesting if you consider that you would expect to see evidence of neutron stars randomly collapsing into a black hole due to the same principle of minute density variations. I wonder which will be proven out? Primordial black holes existing or nailing down the physical existence of quark-gluon plasma in the core of neutron stars? The theories at least, seem mutually exclusive...

    I just like to take a moment to appreciate how incredibly skilled the drawings you guys make are. So cartoony and still extremely realistic! And still so informative, if my physics teacher would try to explain this it would probably take him like 8h. And you do it so fast and informative! Anyways I would love to see a game made by you (with the same art style) to explore the universe and set up bases, starting from earth then say, go to mars and you discover new stuff. I think every viewer would love that! Keep up the incredibly amazing ultra good work!

    If the surface temp. of a neutron star is a million Kelvin what generates this heat? There is no fusion going on in such a "star", so where does the heat come from? Is it from the kinetic energy released during the collapse? Or what? Does a neutron star ever cool down? If not, where's the energy coming from to keep it hot, assuming there is no falling matter colliding with the star? Does this energy come from the inside of the star? If so this energy must provide a counter force to gravitation and a cooling neutron star would compact even more. Could it by this mechanism turn into a black hole?
