Of course Roberts Roberts. How else could it be? After all you, Jean-
Marc Levy-Leblond and Jong-Ping Hsu have discovered that special
relativity would be unaffected if light in vacuum does travel at the
invariant speed of the Lorentz transform and if light in vacuum does
not travel at the invariant speed of the Lorentz transform:

Tom Roberts: "If it is ultimately discovered that the photon has a
nonzero mass (i.e. light in vacuum does not travel at the invariant

Maxwell's equations and QED would be refuted (or rather, their domains
of applicability would be reduced)."

No experiment can refute a theory that would be unaffected if light in
vacuum does travel at the invariant speed of the Lorentz transform and
if light in vacuum does not travel at the invariant speed of the
Lorentz transform. Literally no experiment Roberts Roberts.
