As the Wikipedia article Subatomic particles shows, with respect to the sciences, the atom is obviously not the smallest piece of mass. Apparently, if people have already broken down the atom in to particles smaller than so, why haven't particles been understood yet?
Old scholars reasoned that everything has smaller parts, so what's smaller than subatomic particles?
Or is there a limit in the size of mass, only being able to be small to an extent?
Because mass always seems to keep growing in new fundamental particles discovries, (as the Higgs), but when scaling opposite in size, we reach a limit. Therefore, big always gets bigger, but why does small have limits?.
