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 can’t be sure, but we can predict how quarks as elementary particles should behave, and so far all measurements agree with these predictions. It would be a pretty weird coincidence if quarks were composite particles that just happened to behave in the same way.

All quarks of a specific type (e.g. all up quarks) are identical.
