DOES EVERYTHING VACUUM FREE FALL IDENTICALLY?  Of course! - with one
possible exception.  General relativity and quantum field theory could be
falsified on a footnote for under $100 in consumables.  Academic volunteer
required.

Thanks for replying!  How does a recipient rapidly decide between a
crackpot e-mail and a wildly heterodox but plausible proposal?  First
contact must be brief and technically dense.  It cannot be published
without experimental results.  Nobody would risk reputation without
published basis for pursuit.  Three alternatives:

   1) Faculty with big brass clangers.  The grant funding process renders
such non-viable.  Experiments with assured outcomes and untestable theory
are fundable.  PERT charts and least publishable bits are fundable.

   2) Untenured faculty desperate for a big hit.  See (1).

   3) An undergrad independent study project.  The experiment must be
scaled to ability, time, apparatus, and budget.  Failure is an
option.  OTOH, who wants a pimply kid to earn a Nobel Prize from doing
outside wash?  It still requires gutsy faculty.

Space is postulated to be isotropic and the Equivalence Principle
true.  Nobody has tested for allowed exceptions *consistent with prior
observation.*  It can be done at will, rapidly and inexpensively.  Physics
could be subtly, completely wrong without ever having made a bad
prediction.  (You require a better argument than that, right?)  String
theory and its 10^500 acceptable vacua would simplify.  These are not
well-received statements, yet they have no technically sustainable
counter-arguments short of experiment.

The proposal can be stripped down to concept and experiment.  It gets wordy.

CONCEPT:

Philosophy: Self-consistent gravitation theory must either postulate or
ignore the Equivalence Principle (EP; all local bodies vacuum free fall
identically).  Both classes of theory exist.  Only one can be empirically
true.  Prior observations have only examined their overlap.  They are, of
course, seen to be identical.  So?  They are testable where they are disjoint.

Observation: GR denies exchange of spin and orbital angular momenta.  The
symmetry of the Einstein curvature tensor forces the momentum tensor to be
symmetric.  When spin and orbital angular momenta are being exchanged the
momentum tensor is known to be non-symmetric according to the general
equation of conservation of angular momentum.  Earth's slowing spin causes
lunar orbital recession of 3.84 ± 0.07 cm/year.  Metric gravitation is
fundamentally deficient.  Spin-orbit coupling is always treated as
Newtonian.  Ignoring the problem does not fix it.  Einstein-Cartan theory
containing an affine connection or teleparallel gravitation is necessary.

EXPERIMENT

Affine and teleparallel gravitation allow EP violation by opposite parity
mass distributions.  Do solid spherical single crystals of opposite parity
space groups P3(1)21 and P3(2)21 alpha-quartz violate the EP (e.g., in an
Eötvös experiment) and validate Einstein-Cartan theory ?  If so, space is
empirically anisotropic (chiral pseudoscalar vacuum background).  EP parity
violation falsifies metric gravitation.  Somebody should look.

Gravitation is blind to composition, chemistry, magnetism,
electromagnetism, superconductivity, binding energy...  All nuclei are
gravitationally indistinguishable and chemical bonding does not
exist.  Mass-mass divergence in a parity experiment is contingent upon
opposite chirality mass distributions - the 3-D geometry of anonymous unit
mass isolated nuclei in otherwise identical contrasted volumes of
self-similar crystal lattice.

Defining and calculating quantitative geometric parity divergence of a
point distribution in space is in the refereed literature as ab initio and
semi-empirical approaches.  Both agree that anything growing as opposite
parity crystallographic space groups P3(1)21 (#152) and P3(2)21 (#154), the
quartz group, is maximally parity divergent in the location of its atomic
nuclei independent of identity and bonding.  Cinnabar has a curious
symmetry anomaly that excludes it.  Solution-grown benzil is a convenient
low-melting organic that qualifies.

Eotvos experiments contrast test bodies' gravitational vs. inertial mass as
Earth's inertial spin and gravitational orbital acceleration vectors cycle
orientation over time.  Mass-mass divergence cannot be more than about
10^(-11) difference/average given other observations.  The experiment is
sensitive to 10^(-13) at one sigma. We're talking 90 days in a rare $2
million apparatus plus expensive fabrication of test masses.

Mass-mass divergence in a parity calorimetry experiment is destroyed by
melting the opposite parity crystals into a common amorphous liquid.  If
starting opposite parity states are mass-mass divergent and the end states
are identical with zero geometric parity, the difference in latent heats of
melting must be mc^2 of the mass-mass disparity.  It makes for a fast,
cheap, and sensitive test in a pair of commercial calorimeters.  If a
composition Eotvos experiment is threshold sensitive to 10^(-13)
difference/average, a parity calorimetry test is sensitive to 3x10^(-18)
absolute.

I'm an industrial organic chemist.  If I somehow rigged it in my garage and
observed a consistent /_\/_\H(fusion), the physics community would reject
it out of hand.  The experiment requires an academic setting located
between 40-50 degrees latitude, a couple of weeks of undergrad lab scut
work to grow, sort, and shape the benzil crystals, two (borrowed) $40K
differential scanning calorimeters, and four paired /_\H(fusion) runs
conducted over two days.

If each of the eight /_\/_\H(fusion = zero within experimental error, it's
a bust.  If four /_\/_\H(fusion are reproducibly not zero, the hand tapping
the calorimeter keypad empirically falsified metric gravitation and quantum
field theory at their founding postulates.  That's a fast track Noble
Prize.  "The Man Who Broke Einstein" in the Media.  Etc.  Remarkably, no
prior observation is contradicted anywhere - only parity divergent mass
distributions are active.  There are no natural configurations of matter
that make the mathematics work.

Really.  There is no parity Nordtvedt effect.  Natural quartz is flawed and
racemic, as are all chiral minerals.  The Earth masses 5.9742x10^24
kg.  Wet biomass is 3.6x10^14 kg.  Water is not chiral.  All chiral protein
amino acids are L-configuration.  All chiral natural sugars are
D-configuration.  Of the very small (dry chiral biomass)/(total Earth
mass), meat and wood cancel.  There is nothing net observable for lunar
laser ranging.

Every now and again I send an e-mail to somebody skilled in the
art.  Eventually I'll find a curious physics group.  Dr. Petitjean wrote
the ab initio theory and software to calculate parity divergence.  Almost
all of France is in the latitude band, particularly the University of
Bordeaux.  What are the chances of a chemist and a mathematician convincing
a Department of Physics to pursue an experiment that could fail?

I rigged the first *perfectly* parity divergent molecule, [6.6]chiralane,

http://www.mazepath.com/chiralan.htm

NIST has a wonderful commercial stereochemistry assignment software
module.  It passed some ten thousand test cases before
release.  [6.6]chiralane caused NIST sterochemistry software to be
rewritten.  Petitjean's math has long legs - perhaps long enough to walk to
Sweden in early December.  Somebody should look.

If not you and yours, then somebody else.  "8^>)
