Particles, etc.
Nanok & Crisp..
It gets even worse than that. There are no ultimate "particles". In QM all particles are instances of field effects; at base, only fields exist. To be crude, only twitches of space-time+ which persist and interact.
So there are no ultimate billiard balls. The effort to reconcile physics with intuitive images of hard little things is wasted effort. It cain't be done 'cause it ain't so.
