This is one of the tougher questions. A proper answer would involve a
lot of detailed work that surely would be worth a Ph.D. or two. I guess the
short answer would be the usual one: Any theory will do. As I explained in one
of my most popular blogs, “Theory
Formulation,” even a grossly incorrect theory can get us out of the office,
interacting with the external world. Recent exponential growth in these
interactions has led to corresponding growth in data accumulation. Most of our
observations and experiments have nothing whatsoever to do with relativity or
the BBT. The ones that do, invariably are interpreted from the indeterministic
viewpoint. All the same, the ever-widening, progressive exploration of the
universe nonetheless impinges upon both theories. The one characteristic of the
theories—aether denial—is being inundated by rapidly accumulating data to the contrary. Regressive physicists not looking for
aether have found it anyway. This cannot be openly admitted, of course, because
use of the word is grounds for academic dismissal. Physicists necessarily
working under the old paradigm have learned to handle these findings adroitly,
as Kemp (2012) says so well:
“Various models of the aether are being published in current scientific
journals under different names: Quintessence, Higgs Field, Vacuum Expectation
Value Energy, Zero Point Energy, Weakly Interacting Massive Particles (WIMPs),
and Ground State Energy. All are Aether Theories at their core, each with their
own twist, but Aether theories never-the-less!”
All these are signs of the aging crisis in physics, which might have been
averted altogether if Einstein’s (1920) public relations slip-up had not
been swept under the rug: “There
is a weighty reason in favour of ether. To deny ether is to ultimately assume
that empty space has no physical qualities whatever." It is not quite that
simple, of course. Einstein’s corpuscular theory of light actually requires the
absence of aether. Once aether is reinstated as the medium for the wave motion
of light, both relativity and the BBT will be but museum curiosities. In the
meantime, physics will remain retarded, spending vast sums on all sorts of dead
ends that nonetheless wrest huge amounts of data from the universe. The main
difference between an incorrect theory and a correct one is the efficiency with
which that is accomplished.
Indeterminists, of course, would not agree that there
is a “crisis in physics.” It is what was desired all along. The foundational
assumptions of regressive physics and of the greater society are similar. For instance,
Big Bang theorists and most folks on the planet believe in creation, in
opposition to the Fifth Assumption of Science, conservation (Matter and the
motion of matter can be neither created nor destroyed). Many have tried to ameliorate
this by proposing mathematical singularities, parallel universes, multiverses,
or other embellishments. These only serve to highlight their desperation. As
scientists, they know they should believe in conservation, but they
just cannot. It is an assumption after all. There can be no proof that conservation
holds at all times and in all places. Besides, they have been told to avoid
assumptions. Better to stick with what you believe to be empiricism. At least
you won’t get fired for sticking your nose into philosophy, which mostly is
defunct anyway.
