Why do we say virtual particles violate the law of conservation for a moment if they borrow energy from vacuum that has a density? Isn't it conserved?
I have a question about virtual particles. Why do we say that they violate the law of conservation for a moment if they borrow energy from vacuum that has a density? Isn't it conserved?
Ah, yes. Virtual particles are fascinating, aren't they? The concept of virtual particles is actually tied to the uncertainty principle, which allows for the temporary creation of particle-antiparticle pairs. When this happens, one particle is considered real, while the other is virtual. The virtual particle can borrow energy from the vacuum, but it must pay this energy back within a very short amount of time, in accordance with the law of conservation of energy.
