When a very large star dies, a big explosion occurs, and the explosion forms a nebula. After another 5 billion years, the sun began to expand, the color from the current golden yellow to red, the explosion of the Earth was burned up at once. Then the sun will begin to shrink after the explosion, becoming a star as big as the diameter of the Earth - white dwarf, in the continued light of 10 billion years, and then die. There are very few galaxies with only one star like our solar system. Most of them have two or more stars. When larger than the Sun by a factor of 1.4 explodes, a large amount of iron is produced. When a star 8 times larger than the Sun explodes, as a supernova explosion, the explosion will become a neutron star. When a star 7-8 times larger than the supernova explodes as a very supernova explosion, the explosion becomes a black hole that starts ejecting super-strong nuclear radiation that can reach the boundaries of the universe (the farthest place we can observe), which is the brightest light we can see in the universe. All the matter in our universe is produced by the explosion of a supernova, which, at the moment of explosion, produces a variety of chemical reactions, many of which we have not seen until now. For example, an explosion can generate gold, silver and these substances. Heavier metals than iron can only be generated by the explosion, the end product of nuclear fusion is iron, while gold, silver and uranium these heavier than iron chemical elements can only be generated by the explosion. But we don't know their chemical reactions yet, so gold, silver and uranium are very rare things in the universe. Everything in our world: our flesh, blood, and bones are made of the same chemical elements as a flower or a tree from a supernova explosion (and perhaps our command as well), so it is likely that our world is all a product of stardust.
