Probing the Planck scale with neutrino oscillations

Abstract: Quantum gravity ``foam,'' among its various generic Lorentz noninvariant effects, would cause neutrino mixing. It is shown here that, if the foam is manifested as a nonrenormalizable effect at scale M, the oscillation length generically decreases with energy E as ${(E/M)}^{\ensuremath{-}2}.$ Neutrino observatories and long-baseline experiments should have therefore already observed foam-induced oscillations, even if M is as high as the Planck energy scale. The null results, which can be further strengthened by better analysis of current data and future experiments, can be taken as experimental evidence that Lorentz invariance is fully preserved at the Planck scale, as is the case in critical string theory.

Planck Mass Rotons as Cold Dark Matter and Quintessence

Abstract: According to the Planck aether hypothesis, the vacuum of space is a superfluid made up of Planck mass particles, with the particles of the standard model explained as quasiparticle - excitations of this superfluid. Astrophysical data suggests that 70% of the vacuum energy, called quintessence, is a negative pressure medium, with 26% cold dark matter and the remaining 4% baryonic matter and radiation. This division in parts is about the same as for rotons in superfluid helium, in terms of the Debye energy with a70% energy gap and 25% kinetic energy. Having the structure of small vortices, the rotons act like a caviton fluid with a negative pressure. Replacing the Debye energy with the Planck energy, it is conjectured that cold dark matter and quintessence are Planck mass rotons with an energy below the Planck energy.

Determinism and the gravitational Planck constant

Abstract: A discussion is given of the uncertainty principle in view of the introduction of a Gravitational Planck Constant. The need for such a gravitational constant is shown first. A reduced electromagnetic Planck constant and the analogous reduced gravitational Planck constant are defined as h/e^2 and H/m^2 respectively. An attempt is made to reconcile the quantum uncertainty concepts with a deterministic view of the physical world. This conclusion is achieved trough the detailed analysis of the measurement procedures of physical quantities.
