                  A Proposal to Alter Inertial Mass

Einstein postulated that shape of space creates gravitational
geodesics, and assumed the Equivalence Principle (that inertial and
gravitational masses are exactly equal).  Haisch posits that inertia
derives from an accelerated body's interaction with quantum zero point
fluctuations (ZPF) of the vacuum.  No falsifiable test of either
assertion has been attempted.  Would matter from which ZPF were
measurably excluded fall faster than vacuum free fall?

ZPF are manifest in deviations from uncorrected theory of the Lamb
shift, electron g-factor anomaly, and the Casimir effect - which is
conspicuous.  Two optically flat, parallel, grounded, conducting
plates are positioned less than 10 micrometers apart.  ZPF are
partially excluded from the cavity by boundary conditions.  The plates
sustain a calculated and empirically verified attractive force of
unbalanced surrounding ZPF radiation pressure,

                        F=-hc(pi)A/480d^4

where h=Planck's constant, c=lightspeed, A=area, d=distance separated.
For a 500 nanometer gap the Casimir force is 0.2081 dyne/square
centimeter.  This is 5% of the areal weight of aluminum foil.  A
construct with 1/10 the gap would realize 10,000 times the effect.

Dr. Bernhard Haisch has modeled inertial mass as deriving from an
accelerated body's interaction with ZPF, consonant with a large body
of refereed physics literature.

Proposal:  Vacuum deposit alternating layers of 80 nm reflective,
electrically conductive metallic aluminum and 50 nm transparent
dielectric magnesium fluoride, hundreds of them, upon a large area of
suitable deposition substrate.  Each dielectric gap will suffer ZPF
exclusion by its conducting boundaries.  As etalons, the primary
propagation window is 140 nm, excluding all longer wavelength
radiation and more than 20% at shorter wavelengths.  ZPF exclusion
within this Casimir stack of alternating metallic and dielectric thin
films may alter gravitational and inertial mass commensurately (too
little measured weight for the contained moles of matter), or do it
incommensurately and violate the Equivalence Principle.

By weighted average (Al=2.702 g/cm^3, MgF2=3.14 g/cm^3), the lamellar
construct would have a classical density of 2.87 g/cm^3.  Of that, 1.2
g/cm^3 or 42% will be Casimir Effect ZPF-excluded dielectric.


COMMENSURATE TEST:  Weigh a gram of Casimir matter (and some carbon
black) within a thin-walled silica vacuum ampoule to sub-microgram
precision.  Laser heat (non-contact) to above 700 Celsius to melt the
aluminum and disrupt the lattice.  Does the weight INCREASE?

INCOMMENSURATE TESTS:  Dr. Faller of the University of Colorado
designed and commercialized a laser-monitored corner cube free-fall
gravimeter accurate to one part in ten billion.  Casimir matter is an
optically flat aluminum mirror.  Fashion a hollow corner cube and see
if the expected 9.8 m/sec^2 acceleration obtains vs. a control
experiment with an ordinary hollow corner cube of similar mass and
dimensions.  No body falls faster than vacuum free fall.

There are several industrial vacuum drop towers used for investigating
(transient) weightless processing.  A 100 meter vacuum drop requires
4.52 seconds.  Dr. Faller's desktop device could be scaled up 240
times to one part in two trillion measurement.  With less creativity,
we could break a weak, narrow light beam as between aligned segments
of an optical fiber to start and top timing.  Calibration is dropping
pieces of aluminum and magnesium fluoride.  The measurement need only
be precise.  Will Casimir matter fall faster than vacuum free fall?

Ultracentrifuges spin to 100,000 gravities (the Beckman Optima XL-100
gives 802,000 gravities with a Type 100 Ti rotor), albeit with
mechanical vibration.  An meticulously balanced static rotor, ordinary
vs. Casimir matter, could be spun up and observed.  Angular
acceleration affords closure with linear acceleration.

The desired result is a measured anomaly.  A positive commensurate
test would unify gravitation with electromagnetism through Haisch's
theory - a Unified Field Theorem.  A positive incommensurate result
would provide empirical exception to the Equivalence Principle.

I invite comment, posted or by e-mail.  The experimental fabrication
is typical for a solid state fabrication lab.  Measurement is
absolute:  A body falling faster than vacuum free fall cannot be
otherwise obtained.
