Fusion is a nuclear process that powers the stars; it also provides electricity to homes and businesses; while fission at times is used to induce fusion. The products, the elements produced during these nuclear processes, proceed in the direction of a common element, Ironadmin@physicsforums.com

I have read about the iron core of stars and planets and wondered if there are steel balls floating around the universe. I would think that it is possible to strip the light stuff away from the core. A collision should be able to do it to a planet. Is it possible for a star to burn out without going nova? If so, what would be left?

Aren't the reactors that generate electricity, fission reactors...the Fusion ones, tokamuks, haven't been developed for commercial use, not to the best of my kowledge. Aside from that, fission splits atoms downscale re; periodic table of elements, fusion is the building up to iron.

This is somewhat like the landlord who could not count beyond 10. Therefore he put his bottles of wine in rows and counted the bottles in each row. His butler knew that and stole wine by reshuffling the bottles. Atomic nuclei are bundles of energy packed in a charaxteristic way for each isotope. You can reshuffle the energy of a nucleus into two or more packages and steal some energy. You can also pack the energy of several isotopes into a single package and keep some energy for you. But this possible only if the end products contain less energy than the original product(s), otherwise you must add energy to complete the reaction. (The butler should bring bottles back) . That is why iron is left in the stars. The mean atomic weight of the element Iron, 55.847, shows there is no much energy to steal. Morp

Err... no. RAM has nothing to do with it. Read the article. Nucleon binding energy is what you want.-------------
