What are the underlying structures of multiple primal entities?

[Growler]

If there exists more than one primal entity type, must not then those entities have underlying structure indicating more primitive entities, and does this not lead us to the logical conclusion that there must be a single most primitive entity which composes all that is the universe?

What is a 'primal entity type'?

 

[Growler]

an atom is an entity, at one time it was considered to be the smallest division of matter, but of course via the raisin cookie, Neils Bohr, and the standard model, more primitive entities were proposed to exist. There are multiple quarks in the standard model... if 2 quarks differ in their properties, mustn't they have underlying structure?

Well, those primary entities would be the four fundamental forces, from which the entire universe - including all matter - sprung.
We know that, at sufficiently high energy, three of those forces were unified, and we're working on the fourth.

This is a bit philosophical, which we don't allow at PF. If you would like to start a technical discussion (at the B=Basic level) about fundamental particles, please read the following links and also do some Google searching for mainstream technical articles about fundamental particles and forces (the reference links at the end of the Wikipedia articles are also a good place to start). Then start a new thread in the technical Physics forums with links to your reading and ask the specific questions that you have about that reading. That would be a good thread start at the B level.

This thread in the General Discussion forum is now closed.
