Wheeler-Feynman absorber theory

Wheeler-Feynman absorber theory is named for its originators: John Archibald Wheeler and Richard Feynman who wrote 2 papers in 1945 and 1949.

It is an interpretation of electrodynamics. The solution of electromagnetic field equations must be invariant under time-reversal transformation. 

There is no apparent reason for a time-reversal symmetry breaking.
