How can electron escape its infinity?

Question

Quantum theory says that at the interaction of the electron
with the vacuum, the energy and mass of it become infinite.
How can electron escape its infinity?

Answer 1

Early quantum field theory (QFT) attempts led to divergences in field energy for point-like charges. This was an obvious problem, and has certainly not been ignored. More analysis was performed, and the concepts of regularization and renormalization in QFT were created to handle the more rigorous exploration of the effects. The current understanding is that the potentially infinite quantities actually cancel each other out, and what emerges from this "subtraction of infinities" is a theory that can make accurate predictions to 9 decimal places.

Answer 2

Quantum interacting pairs.

Answer 3

you have the question backward. The electron is obviously ok--the question isn't any remember if quantum theory has a fashion of self-consistently calculating the electron's mass and value. It does--the technique which helps this calculation is "renormalization."

Answer 4

when the photon enrgy reaches the threshold
