A modification to the time–energy uncertainty relation in quantum gravity has been interpreted as increasing the duration of fluctuations producing virtual black holes with masses greater than the Planck mass. I point out that such virtual black holes have an exponential factor arising from the action such that their contribution to proton decay is suppressed, rather than enhanced, relative to Planck-mass black holes.

Possible Duality of CBE and Penrose CCC Cyclic Cosmologies

In a cyclic entropy model in which the extroverse is jettisoned at turnaround with a Come Back Empty assumption, we address matching of the contraction scale factor $f(t_T)a(t)$ to the expansion



Dangerous implications of a minimum length in quantum gravity

The existence of a minimum length and a generalization of the Heisenberg uncertainty principle seem to be two fundamental ingredients required in any consistent theory of quantum gravity. In this

Vacuum Instability and Higgs Scalar Mass

A procedure is given to estimate the decay probability of a metastable vacuum state in quantum field theory. As an application, in the Weinberg-Salam model the lower bound (for theta/sub W/=35degree)

Proton Decay, Black Holes, and Large Extra Dimensions

We consider proton decay in theories that contain large extra dimensions. If virtual black hole states are allowed by the theory, as is generally the case, then proton decay can proceed via virtual


Cosmological data reveal a dark energy with a negative equation of state w=P/ρ 0 to Λ=0 in an assumed first-order phase transition. From arguments about stimulated nucleation it is shown that the

SPECIAL ISSUE: Violation of CP in variance, C asymmetry, and baryon asymmetry of the universe

This form of notation is connected with the quark concept; we ascribe to the/?, n, and Л quarks n c = + I, and to antiquarks, и,. = — 1. The theory proposes that under laboratory conditions processes
