What about Conservation of Mass?

What about it?

I can probably explain whatever you're wondering about, but it's completely slipped under my radar.

Question - have we ever broken a neutron and "seen" its quarks, or is this just the answer that we get by solving a particular quantum model?

Blargh. Didn't figure out what you were saying until after I had posted.

Conservation of Mass is just another way of expressing mass-energy equivalence. (For a rest mass, e=mc^2). So it's perfectly fine to gain mass m if you lose energy e such that m=e/c^2. Hope that's what you were asking.

Yes, we have.
