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?

We find new particles by smashing particles into each other and find the trace of the path left behind by the different parts. If quarks are made up of other stuff, that should fall apart too if the energy is high enough (i.e. speed with which we smash the particles into eachother), but we haven’t observed that yet. So either, they are not made up of other parts, or the energy we tried isn’t high enough.
