Abstract (EDP Sciences, SpringerLink, SAO/NASA ADS)
An elementary account on the origins of cosmic chaos in an open and multiply
connected universe is given; there is a finite region in the open 3-space in
which the world-lines of galaxies are chaotic, and the mixing taking place in
this chaotic nucleus of the universe provides a mechanism to create
equidistribution. The galaxy background defines a distinguished frame of
reference and a unique cosmic time order; in this context superluminal signal
transfer is studied. Tachyons are described by a real Proca field with negative
mass square, coupled to a current of subluminal matter. Estimates on tachyon
mixing in the geometric optics limit are derived. The potential of a static
point source in this field theory is a damped periodic function. We treat this
tachyon potential as a perturbation of the Coulomb potential, and study its
effects on energy levels in hydrogenic systems. By comparing the induced level
shifts to high-precision Lamb shift measurements and QED calculations, we
suggest a tachyon mass of 2.1 keV/c2 and estimate the
tachyonic coupling strength to subluminal matter. The impact of the tachyon
field on ground state hyperfine transitions in hydrogen and muonium is
investigated. Bounds on atomic transition rates effected by tachyon radiation
as well as estimates on the spectral energy density of a possible cosmic
tachyon background radiation are derived.
