Hello. I read recently that the law of conservation of energy can be violated for very short time intervals, according to the uncertainty principle. Apparently, this fact gives rise to virtual particle production from the vacuum. Once we accept that the uncertainty principle allows the laws of physics to be broken, even for a very short time, then what is the uncertainty principle? Is it a law of physics, or a "super law" beyond all others? Most importantly, I want to know if the uncertainty principle allows the Pauli exclusion principle to be violated, if even for an extremely short time. According to the principle, if all electrons in the universe are "aware" of the quantum states of all other electrons, what happens when virtual particles are randomly created close enough to an electron in an atom to affect its energy? (The Lamb shift is proof that virtual particles have a real impact on the energy levels of atoms). If the exclusion principle cannot be violated at all, then spacetime itself has to "be aware" of the quantum states of all electrons contained within it to make sure that the virtual particles it produces do not impart energy to an electron so that its new energy coincides with the energy that any other electron in the universe already possesses. What are your thoughts on this? Thank you in advance.
