Uh, after those temperatures and pressures diminished, then they became elements.That's what I meant but if elements can't exist at those pressures and temperatures, how did they become elements in the first place?
You're not just talking about collisions, you're talking about immense temperatures. Gluons and quarks existed first, then when it cooled down enough, protons and neutrons, then when it cooled down further, electrons, then when it cooled down further, helium and deuterium.We now know that H becomes He and so on from fusion but if the pre-Bang particle soup suddenly expands, as far as I know, sub-atomic particle collisions don't create new elements, they just release energy and leave some kind of trail, which is how they proved quarks exist. They could only see the trail from the energy but none has actually been seen.
I don't really understand the problem. The universe is mostly empty space, and atoms are mostly empty space. The universe is quite, quite, empty.If subatomic particles take up their given space and none were created during the Big Bang, how is it possible for these same particles to take up so much space now?
If elements are compressed enough, they're either destroyed or fused, right? What happens to subatomic particles?
They're "destroyed" in that they're broken up into subatomic particles and no longer exist as elements. They existed as elementary particles.
