Inertia and Gravitation in the Zero-Point Field Model
Haisch, Bernhard · Rueda, Alfonso
In one minute
NASA’s March 2000 final report records Haisch and Rueda’s four-year study of an electromagnetic zero-point-field account of inertia. They model an accelerating object as seeing an asymmetric momentum flux in a field that is isotropic at rest; scattering of that flux supplies a reaction force. Their derivation is intended to recover F = ma and the relativistic equation of motion, with an inertial-mass parameter determined by the object’s scattering response. They also connect a proposed Compton-frequency resonance to the de Broglie wavelength of a moving particle. The report develops a route from the equivalence of inertial and gravitational mass to a polarizable-vacuum picture of gravitation. It identifies open steps: a fully relativistic inverse-square account, treatment beyond electromagnetism, and a measured scattering resonance.
Connection
This is the primary source under chapter 3: inertia and gravity as effects of the zero-point field rather than brute facts of matter. It is also why chapter 8 can ask a practical question — if mass is a coupling to a field, it is something an engineer might one day tune.
From the source
Inertia is not intrinsic to matter. Accelerate an object and the zero-point field’s momentum flux, perfectly balanced at rest, becomes asymmetric; the recoil from scattering that flux is the inertial reaction force.On the relation between inertial mass and quantum vacua, §4
The derivation returns Newton’s f = ma and its relativistic form from Maxwell’s equations applied to the zero-point field, with inertial mass appearing as an integral over the zero-point spectrum weighted by how strongly matter scatters it.On the relation between inertial mass and quantum vacua, §4, Eq. (7)
A charge driven to jitter at its Compton frequency by the zero-point field produces, once it moves, a beat pattern whose wavelength is exactly the de Broglie wavelength — so the wave nature of matter and its inertia come from one mechanism.On the relation between inertial mass and quantum vacua, §5
Because inertial and gravitational mass must be equal, gravity should come from the same field — Sakharov’s 1968 conjecture, developed as a vacuum whose dielectric properties change near matter and so mimic curved spacetime. What to watch: Carlip’s challenge leaves the inverse-square step for a fully relativistic model to settle.On the relation between inertial mass and quantum vacua, §6
The zero-point energy density implied by a Planck-frequency cutoff is enormous, and the authors argue it need not curve the universe: if gravity is itself a secondary effect of charged particles driven by the field, the field cannot act on itself to gravitate. What to watch: a theory of gravitation built on that premise that also predicts gravitational waves.Inertia: Mach’s Principle or Quantum Vacuum?, The Quantum Vacuum Approach; and §6 of the companion paper
If mass is a coupling parameter rather than a substance, the coupling is in principle adjustable. What to watch: the scattering resonance the authors set out to locate, the stated target of their STAIF-2000 paper on zeroing in on the zero-point-field inertia resonance.list of contract papers; STAIF-2000, AIP Conf.
