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.

    so if you think about it, even if earliest space intelligent life was in existence, they wouldn't have developed technology purely because the space they were living in lacked heavy resources....? According to videos humans are in the early stage of space too, so perhaps there are things that just don't exists in the universe yet for us to find. hmm...

    Through a 13 billion year journey starting with the big bang, leading to the formation of a supermassive star, which eventually collapsed into a neutron star, which collided with yet another neutron star, causing a supernova, whose interior coalesced into gold, which in turn combined into our planet and was later mined and turned into conductors on the circuit board in my computer, which I then use to watch porn online.

    The cycle is kind of similar to the Hindu God's theory. The creator and destroyer gets born and begins to make world. And after 100 age of the creator, the destroyer destroys the world and both the creator and the destroyer of the world also gets destroyed. And a new creator and destroyer is made. In Hindu mythology,our world repeats in a cycle. It is also said that every new creator and destroyer are not sure of their purpose and only when the supreme source of God tells them their work, they begin to make the world. The supreme source is said to be source of everything including the good and evil gods.

      "over millions of years, these atoms mix back in to the galaxy" stuff from the neutron stars gets spewed out, and not all of it is consumed by the black hole. the stuff that doesn't fall into the black hole can mix into planetary nebulae over millions of years, and as stars form from the nebulas, planets and asteroids form from the elements spewed from the neutron stars.
