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.

    Sie haben die Magnetare kaum erwähnt. Magnetare und Neutronensterne sind nicht dasselbe. Neutronensterne befinden sich in ihrem endgültigen Zustand, also sind sie stabil, aber Magnetare sind instabil, so dass ihre Gravitationskraft instabil ist, also ist das Gefährlichste im Universum der Magnetar.

    Well, it is amazing for the circle of life and place to repeat itself by killing itself once and twice to create us and the planets before us. But we can not deny that it´s going to restart again and again, for that to happen it needs to end the old one to create the new one. And soon we'll be a part of its past just like everything else before to create a new future for itself to be a past for something else.

    Real quick: when you said that the magnetic fields of neutron stars are a quadrillion times stronger than the Earth's, once you do the math I think something is a bit different than what you said. Earth's magnetic field: 0.00005 Tesla \/ x2,000,000,000,000,000 \/ Neutron star magnetic field (upon birth): 100,000,000,000 Tesla

    New particles don't just appear At first stars are massive clouds of hydrogen. Then the sheer gravity squeezes the atoms together. This fuses the atoms into other elements as their nuclei combine. We call this nuclear fusion (not to be confused with nuclear fission) There's a list of elements that stars fuse together that u can look up. From carbon to silicon. All u need to know is u cannot fuse iron. Anymore pressure than that u get a black hole
