Default big bang query

is there any way that the big bang could have been produced by fission rather than fusion, and that the fusion that we see nowadays is just the coalescing of the same separated matter?

my knowledge of the energy released in fission is very limited, but i am curious nonetheless.

hmmmmm how to explain this,,, well to be brief no, if it had there would not be so many different elements, and while all elements can react to fusion not all can react to fission. Don't know how much that helps, but I simply cant explain further without going into what fission is and most probaly confusing us both

i have a pretty good understanding of fission. i was just wondering if it were possible on any level. fusion still makes more sense to me, but i wanted to explore the idea.

yaknow, thinking about it I supose it is posible only it wouldn't have been created by fision, but destoyed by it and the matter we see today is simply the universe trying unsuccesfully trying to put itself right

The Big Bang was caused/fueled by neither fission nor fusion. Entirely different forces and processes involved.

Nucleons themselves didn't form until about 3 minutes after the initial event. Before then the radiation environment was hard enough to photodisintegrate things as mundane as protons and neutrons. Once things expanded and cooled, nucleons could survive, and once that started, some of them fused to make heavier elements. Not many of those, though. Trying to build up heavy nuclei just by slamming pairs of them together doesn't work when the mass 5 nucleus disintegrates as fast as it can figure out what it is and the mass 8 nucleus is also unstable and disintegrates back to two alpha particles. And, the whole thing cooling and expanding, and very quickly nothing has the energy to overcome the electrostatic repulsive forces deeply enough for the strong force to take over and bind nuclei together. So you end up with mostly hydrogen, nearly all the rest helium, a trace of lithium, and an even smaller trace of beryllium.
