Modern Michelson Morley experiment can be used to test both the classic Stokes - Planck and the
New Galilean Age paradigm views for entrained ether theory. These two approaches lead to a
significant different quantitative prediction of the expected beat frequency modulation from the
(adapted to crossed resonators) laser couple beams interference. The modulation is due to variation
of the two way light velocities module difference between the crossed resonators orthogonal
directions. The modulation to nominal laser frequency ratio prediction is apparently falsified by
Modern Michelson-Morley experiment negative outcome in highly rarefied gases that actually pulls
its detection limit till10. This detection ability is criticized by present author. Moreover an
improved frequency counter acquisition setup inside Modern Michelson-Morley experiment is
proposed in order to detect the beat frequency modulation. This change will allow determine the
better prediction among the one offered by Stokes ? Planck classic view and the one by the New
Galilean Age paradigm.
