This question already has an answer here:
Quantum physics tells us that even a perfect vacuum be populated by "virtual" pairs of subatomic particles. I have read that these particles are allowed to violate the Conservation of Matter and Energy because they do so for such a short amount of time before annihilation that they don't count. I don't buy it. As we.have established that "Virtual Particles" are "real" (by virtue of the fact that well known processes don't occur with out them) . The question still begs. As no conversion is 100 percent efficient ( a photon is still left in our reality even after annihilation) To preserve the laws of physics, the energy to create them must come from somewhere. * .Given this, I have two questions:
- Have " virtual" pairs ever been observed and/or isolated?
Where do "virtual" particles come from? (As they would have to come from somewhere to satisfy conservation; regardless of how short a time they spend in our universe.)
- post is edited and reflects (to clarify what I am asking) information discussed below where Question 1 is answered. Question 2 remains.
