Hello everyone,
I was wondering, how do real particles interact with virtual particles created by the vacuum.
For instance, wouldn't a electron travelling through space regularily interact and annihilate with a virtual positron from a pair of virtual positron-electron created by the vacuum? If that were to happen I guess the remaining virtual electron would become real and would sort of replace the original electron... I don't know.
How can a particle exist for billions of years without annihilating with a virtual particle?
Nick.
