Your sense of reality is a bit distorted.<quoted text>
Both can be proved. The effects of virtual particles can be measured and muons definitely decay.
Those alleged muons are jailed by the forces about them. They need to change for the decay to happen. They are corralled within a collection of forces which in turn are corralled by larger forces without. They are captured energies forced into a circuit by the larger universe. Part of the Big Bang thingy of being a contained system of matter and energy, conservation of matter and energy, and all of those other things we assume to be true,
Now, a careful reading of that article, and most any other physics article, will reveal a certain circular logic within the observation process and system based upon math which is based upon perhaps some wrong assumptions made much earlier in the development of the system of said observation process.
Your "reality" based upon such is a delusion.
