Charge-Nonconserving Decays

Interesting ambiguities associated with the possibility of charge-nonconserving decays are pointed out. Such decays or $e^{-}\leftrightarrow e^{+}$ oscillation could quench electrostatic potentials larger than several million volts. A connection to the Feynman diagrams and infrared divergence is pointed out, and a simple intuitive space-time picture suggests that $m_{\gamma }\le {10}^{-15\mathrm{}}$ eV implies very long decay times for charge-nonconserving decays.
