Vacuum zero-point field pressure instability in astrophysical plasmas and the formation of cosmic voids
Alfonso Rueda · Bernhard Haisch · Daniel C. Cole
In one minute
Alfonso Rueda, Bernhard Haisch and Daniel Cole take the zero-point field out of the laboratory and put it in the sky. Their starting point is a result of Einstein and Hopf, brought up to date: a particle drifting through ordinary radiation feels a drag, because its own motion Doppler-shifts the light ahead of it into a headwind. The zero-point field has no headwind, because its spectrum looks identical from every moving frame. So the field’s kicks accumulate and are never damped, and an isolated proton in near-empty space slowly gains energy. In the thin plasma between galaxies, the authors argue, that has a visible consequence: the emptiest regions are energised most, push outward, and compress their surroundings into sheets — until magnetic field lines trapped in the compressed gas push back and the structure locks. Galaxies and clusters then form by gravity inside those walls. The paper works the model to numbers, shows that no thermodynamic law is broken, and names what would settle it.
Connection
Chapter 2 argues that the vacuum is a real, structured medium rather than a bookkeeping term, and this paper asks what such a medium would do at the largest scale there is — answering that it would carve the foam of voids and walls that redshift surveys actually show. Chapter 13’s unified picture, one field standing behind inertia, gravitation and cosmic structure alike, is stated by the authors themselves in their closing paragraph.
From the source
Because the zero-point spectrum is Lorentz invariant, a particle moving through it feels no Doppler drag, so the excitation the fluctuating field delivers is never balanced by dissipation. An electromagnetically interacting particle isolated in that field therefore undergoes secular acceleration — a steady, continuing growth of translational kinetic energy.Section 2.2, ‘The ZPF-Acceleration Effect’
The effect is quenched for electrons, whose zero-point-induced zitterbewegung is relativistic and time-dilates the response, and acts on protons and nuclei instead. The authors point to the complete absence of an electron component in the highest-energy primary cosmic rays, where protons and nuclei are seen to beyond three times ten to the twentieth electronvolts, as a hint of confirmation.Section 2.2, closing paragraph
In an ultralow-density, fully ionised electron-proton plasma the acceleration is not damped by collisions, so it energises the most rarefied regions preferentially and builds a pressure gradient pointing opposite to the density gradient: regions of lower density expand at the expense of regions of higher density.Abstract; Section 2 opening; Section 4
The expansion is eventually halted by the magnetic pressure of field lines trapped in the compressed, high-density plasma. Volumetric and longitudinal expansion-compression factors are computed and tabulated for three candidate eras of void formation, at redshift 20, 50 and 100.Section 4; Table 1
No law of thermodynamics is broken. The particle’s kinetic energy gain is compensated exactly by the change in the zero-point plus Planckian radiation, and Clausius’s statement of the second law implicitly assumes a process that begins and ends in thermal equilibrium — which a particle in near-vacuum, acted on only by the zero-point field, is not.Section 5, ‘Thermodynamic Considerations’
What would settle it, in the authors’ own words: whether the void and wall structure stays stable after it forms, and whether the model can be fitted quantitatively to the best present-day astrophysical observations. They add that if this, the zero-point-field account of inertia, and the Sakharov and Puthoff account of gravitation all hold, the result is a paradigm shift in cosmology.Section 6, ‘Discussion and Conclusions’
