It has been argued since 1948, when it was experimentally demonstrated, thatthe Casimir effect-where two non-charged conducting plates have a weak butmeasurable force on each other dependent on the inverse fourth power of thedistance between them-shows the reality of vacuum zero-point fluctuations. This"proof" of the reality of vacuum fluctuations has been repeated in many quantumfield theory books and papers subsequent to 1948. The attractive force isgenerally ascribed to the difference in zero-point energy of theelectromagnetic field between the plates and the vacuum external to them. As iswell known, zero-point vacuum fluctuations are incompatible with relativisticphysics and are at the root of the "cosmological constant" problem. Most textson quantum mechanics and quantum field theory eliminate the vacuum energy bynormal ordering or some other mechanism. These issues are explored in thispaper and it is pointed out that a means to resolve them already exists.
