We can say that a particle has a position, a momentum and an energy but a particle doesn't have a time. Mathematically that means that in quantum mechanics position, momentum and energy are all Hermitian operators but time is not.

If you assume that virtual particles are real you are then able to make the most precise theoretical prediction not just in physics but in all of science, one part in 10 trillion. The theory of Quantum Electrodynamics, which is about virtual particles, predicted that the electron's magnetic moment should be approximately 0.001,159,652,181,643, the most accurate experimental measurement says it's approximately 0.001,159,652,180.* > *even though they contradict Conservation of Energy. * > *In quantum mechanics you can borrow mass/energy from nowhere but you have to pay it back, and the more mass/energy you borrow the shorter amount of time you have before you have to pay it back; that's why you will never be able to directly observe a virtual particle, however you can observe effects caused by those virtual particles. * * > Are you aware of this fact?* *Of course I'm aware of it! In Quantum Mechanics the law of conservation of energy had to be modified. And it's not just Quantum Mechanics, in General Relativity the law of conservation of energy is true locally but not at a cosmic scale. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* kfa -- You received this message because you are subscribed to the Google Groups "Everything List" group.
