The phase coherence of light from
extragalactic sources direct evidence against
first order Planck scale fluctuations in time
and space
extract.
----------------------------------------------------------------------
Nevertheless, the obvious test bed for quantum gravity has indeed been
provided by this Gpc distance source; the outcome is negative. No doubt
one anticipates interesting propositions on how time and space may have
contrived to leave behind not a trace of their quanta.Thus, from Michelson-
Morley to extragalactic interferometry there remains no direct experimental
evidence of any sort that compels us to abandon the structureless, etherless
space-time advocated by Einstein. These points, together with in-depth
discussions on how Planck scale phenomenology affects the appearance of the extragalactic sky, will be the subject matter of a paper by Ragazzoni and colleagues.
