I do think, that there are always smaller particles. I think that the smallest one don't exist.
I don't know alot about quantum physics, but i think that this line of physics study particles smaller then atoms named quants. And neutrinos are one of them. They still got mass, but they cannot be measured easilly, beacause of their size and speed.

In chemistry and physics, an atom is the smallest particle still characterizing a chemical element.
The word ''átomos'' is usually translated as "indivisible" or "uncuttable."
Atoms are the fundamental building blocks of chemistry, and are conserved in chemical reactions.

How much do you learn this way, Matjaž? What I read as your comment are really other people's sentences. Be fair and mention the original source.
