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?

it should be noted that we have actually proven the smallest possible things in energy (1 photon), in electrical charge (1 electron) and in size (the planck length).

it’s notable that a quark is 10^10 larger than a planck length, a proton is10^3 larger than a quark, and an average atom is 10^6 larger than an average proton.

As such it feasible to have 2 or 3 more “levels” of particles before we run out of room, but it is rather unlikely at this point.
