Here is an alternate theory that
http://arxiv.org/pdf/hep-th/0503158v1.pdf *The Casimir Effect and the Quantum Vacuum* * * *In discussions of the cosmological constant, the Casimir effect is often invoked as decisive evidence that the zero point energies of quantum fields are “real”. On the contrary, Casimir effects can be formulated and Casimir forces can be computed without reference to zero point energies.* ** * * *They are relativistic, quantum forces between charges and currents. The Casimir force (per unit area) between parallel plates vanishes as a, the fine structure constant, goes to zero, and the standard result, which appears to be independent of a, corresponds to the a→¥ limit.* In the standard theory, the Casimir force is the zero point energy as calculated by computing the change in the zero point energy of the electromagnetic field when the separation between parallel perfectly conducting plates is changed. The result, of the casimir force equation seems universal, independent of everything except ¯*h*, *c*, and the separation, inviting one to regard it as a property of the vacuum. This, however, is an illusion. When the plates were idealized as perfect conductors, assumptions were made about the properties of the materials and the strength of the QED coupling a, that obscure the fact that the Casimir force originates in the forces between charged particles in the metal plates. This is another way at looking at it.
