Lectures on Cosmology and Action at a Distance Electrodynamics (World Scientific Series in Astronomy and Astrophysics, Vol 1) (Buy Now)

Jayant Vishnu Narlikar
This book describes the subject of electrodynamics at classical as well as quantum level, developed as an interaction at a distance. Thus it has electric charges interacting with one another directly and not through the medium of a field. In general such an interaction travels forward and backward in time symmetrically, thus apparently violating the principle of causality. It turns out, however, that in such a description the cosmological boundary conditions become very important. The theory therefore works only in a cosmology with the right boundary conditions; but when it does work it is free from the divergences that plague a quantum field theory.
