Sun And solar system start like a cloud of dust Wich comes from old supernova. IT should build on Gravity of heavier stuff like iron, gold, lead, uran,Mercury etc. In the center. Like our planet have high concentration of heavy elements, mostly iron. Should not be the same case with every other planet even more with stars? Instead i read of metal hydrogen in core of Jupiter And fusion of hydrogen in Sun. Should not they be full of heavy stuff And the light stuff float out?
In: Planetary Science
Most of the matter in the universe is hydrogen. For large objects like Jupiter or the sun the vast majority of the matter inside them is hydrogen as well. There are heavier elements in the core of both Jupiter and the sun, but those heavier elements are outnumbered by the massive amounts of hydrogen, so the core of both of these bodies is mostly hydrogen.
