Any "ether" whose energy density is proportional to the cube of its
frequency, when this ether possesses a black body spectrum of frequencies,
will be Lorenz invariant so that uniform motion relative to such a
space-filling medium remains undetectable. The Michelsom-Morely experiment
in no way demonstrates the nonexistence of a space-filling medum, i.e., ether.

Moreover, if the ether is composed of fluctuations in energy such that the
ratio of the positional uncertainty, /\x, to the time uncertainty, /\t, of
these energy fluctuations is the speed of light in vacuum, i.e, /\x / /\t =
c, then motion by massive objects relative to such a space-filling medium of
energy fluctuations will likewise be unmeasureable/undetectable. This is
because the distance, x, moved by an object (travelling less than c) relative
to any given vacuum energy fluctuation in time, t, during the time that this
fluctuation is in existence, i.e., /\t, must be less than /\x, the positional
uncertainty of this fluctuation, so that the relative distance which the
object is supposed to have travelled relative to the fluctuation is x < /\x,
and hence is not measurable as a real interval of displacement. The vacuum
of quantum theory, possessing a theoretical energy density of greater than
10**95 kg/m**3, is composed of just these sort of energy fluctuations. And
although the expectation value of the vacuum in free space is indeed
virtually 0, the square of the energy of these fluctuations are finite, in
fact, bordering on infinite in density (as suggested by the figure above).
Now if massive particles of which all matter is composed are merely flux
stabilities of such vacuum energy fluctuations, then intuitively we should
not expect any motion of these flux stabilities relative to the fluctuations
composing them - any more than one would expect an icon drifting across one's
computer desktop to possess a motion relative to the matrix of toggling
pixels forming the wallpaper of one's computer screen.
