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?

Modern physics has a concept called the Planck Length, which is 1.616255×10−35 m. One way to think about it is that is essentially a limit of “smallness” beyond which we could never look. To grossly simplify a complicated subject, according to the laws of physics as believed today, just like there is nothing that can exceed the speed of light, there is absolutely no possible way we could ever measure or observe anything at such very small sizes.
