Query: Interpretation of the slight periodic displacement in the
  Michelson-Morley experiments   The slight periodic displacements in the Michelson-Morley interference
experiments do not show ether-drift; however, they do show the effects of the
theory of general relativity that is, the effects of acceleration and
deceleration to the interference condition of the Michelson-Morley interference
experiments. Therefore, these slight periodic variations are very significant
and important for strengthening the theory of special and general relativity.
The slight periodic displacements are discussed from the viewpoint of the
theories of general relativity and interference.
