every interaction an infinite-body problem. Moreover, this
“polarization of the vacuum,” apparent in measurements even
then, has since been rigorously verified (Pais, 1994). The Dirac
theory (1934) required every charge to be surrounded by
unlimited numbers of the opposite charged ends of electron-positron
pairs (henceforth “epos”). Experiment verified that
the epos were both present and necessary.
