Well I do know a bit about physics - its my line of work. Quarks and leptons are the fundamental particles

- if you can find one smaller then you are a shoo in for the Nobel and I would love to have your autograph or even a discarded kleenex from you. And mass can indeed be destroyed. For one thing it can be converted into energy and energy back into matter - remember E=MC^2 ?- thats the conversion formula. This is a routine operation in a big accelerator. Also, matter both appears and vanishes spontaneously in the vacuum - its a quantum effect due to the uncertainty principle - empty space foams with evanescent matter. Actually this is the basis of an important result by Hawking who showed that black holes will decay because of this evanesence on the scwarzchild radius. The particles appear in pairs matter and anti matter - sometimes one of the pair is sucked into the black hole before it can recombine with its anti pair and vanish. In this way the black hole slowly bleeds energy and turns "brown"

I dont see how you establish the existence of "spirit" sure you believe that the universe is constructed on a duality and that symmetry strongly suggests to you the existence of a spirit world - but this is all your opinion - the question was on proof

So where are we so far? Not one shred of evidence or proof - just opinions - which are ten a penny
