  We report a simple re-analysis of the old results (1887) from the
Michelson-Morley interferometer experiment that was designed to detect absolute
motion. We build upon a recent (1998) re-analysis of the original data by
Munera, which revealed a small but significant effect after allowing for
several systematic errors in the original analysis. The further re-analysis
here reveals that a genuine effect of absolute motion is expected, in what is
essentially a quantum interference experiment, but only if the photons travel
in the interferometer at speeds V< c. This is the case if the interferometer
operates in a dielectric, such as air, as was the case, incidently, of the
Michelson-Morley experiment. The re-analysis here of the Michelson-Morley
experimental data, correcting for the refractive index effect of the air,
reveals an absolute speed of the Earth of v=359+/-54 km/s, which is in
excellent agreement with the speed of v=365+/-18 km/s determined from the
dipole fit, in 1991, to the NASA COBE satellite Cosmic Background Radiation
(CBR) observations. Other experiments where the interferometers operated in air
(Miller 1925,1933) or helium (Illingworth 1927) give similar results when
re-analysed. These experimental results refute Einstein's assertion that
absolute motion through space has no meaning.
