in the answer, it was said that virtual electron-positron pairs could be made real by using a powerful electric field. since the electron carries positve energy and the positron carries negative energy which when combined equal zero, would the field have to generate enough energy to make only the negative energy particle real, or would it have to add energy to both? how would the enegy from the field make the virtual pairs real? it is my understanding that virtual positrons and electrons are not the same as real positrons and electrons. in real particles, both the electron and the positron have positive energy which when annialated leave behind the energy equal to the 2 particles. in virtual pairs the electron carries positve energy and the positron carries negative energy which when annialated leaves behind 0 energy because it is all returned to the vacuum. do virtual particles have charge, or do they call them virtual electrons just to make it simple to understand? also when the casmir effect is observed, how is the energy from moving the plates returned to the vacuum, for once the plates are openned they remain that way unless energy is applied to close them?
