How do we know things don’t just get infinitely smaller? If a quark is the smallest particle we know of, what makes up a quark? And so on?

It also makes me wonder if everything is actually the same? I know it’s a silly question, but are all quarks the same (composition wise) if so, does that mean that at our smallest core, we are made up of the same thing? Does this also mean that if not, that there is always going to be variance even to our smallest level? I suppose this question is asking more about what exactly is the composition of the smallest possible particle, and is there really an end?

If we could break it down, our current models require more energy than is in the universe to break it down. It already takes an absurd amount of energy we can’t harness to even keep a quark in isolation. The energy density of the universe is so low at this point that it likely will never happen again.

We believe that there is a quark field, and a lepton field, and quarks and leptons are just disturbances in that field. The type of disturbance determines which type of quark/lepton it is.
