new project, - understanding sub-atomic particles
Posted 13 April 2013 - 09:12 AM
My "spread sheet" would be a very large piece of paper that I can draw on, move things around and possibly make connections of forces etc.
Any recommended web sites that has already done this?

Time is quantized? There was no Big Bang, just a before and after??

Can someone explain why a meson can be formed by matter and antimatter combined without annihilation?

They do in fact annihilate when the pairs involved are conjugate. If you consult this table you will see that mesons made from conjugate quark-antiquark pairs, like the pi_0 and the eta, have very short lifetimes compared to the ones made from dissimilar pairs like the pi_+. An "up" quark can only annihilate with an "up" anti-quark. So the up-anti-down pair is relatively stable.
It is also possible also to make a bound state from a positron and an electron. This material, "positronium", is short-lived, but has been confirmed to exist.
