Hey, I haven't looked up too much on this subject, but I was reading up on leptons and quarks (actually, the book was "In Search of the Big Bang, by John Gribbin, quite a good book too), and it was saying how matter is made up of leptons and quarks, and then doubly duplicated by heavier unstable particles. It then went on to claim that the heavier, unstable particles have completely no effect on physics or the world around and, and their only purpose is to complicate particle physics.

Is there any updates on this? The book is kind of old.

By heavier unstable particles are we referring to things such as stranges and charms, or moreso top and bottoms?

I'm a bit confused here.

Despite what has been published about our knowledge of quantum mechanics, we are still far from being able to speak definitively about the model of the universe based upon our observations of leptons, quarks, muons, gluons, stranges, strings, and the whole nine. I think it would be prudent before we prove or disprove Occam's Razor based on this.

For the record, I'm not trying to debunk occam's razor, I just want to find out more about this. The book claims particle physics would be unchanged if only the electron, neutrino, and up and down quarks existed, but things are more complicated then that.

Don't know why that reposted, and I can't delete it, so please disregard.
