The reported anomalous acceleration acting on the Pioneers space-crafts could be seen as a consequence of the existence of some local curvature in light geodesics when using the coordinate speed of… (More)

The detected anomalous frequency drift acceleration in Pioneer's radar data finds its explanation in a Berry phase that obtains the quantum state of a photon that propagates within an expanding… (More)

The unsteady laminar flow and heat transfer characteristics for a pair of opposed confined impinging air jets in 2D and 3D were studied numerically. The present study continues the authors' earlier… (More)

It is shown that a wave vector representing a light pulse in an adia-batically evolving expanding space should develop, after a round trip (back and forth to the emitter) a geometric phase for… (More)

The semiclassical approach to quantum gravity would yield the Schrödinger formalism for the wave function of metric perturbations or gravitons plus quantum gravity correcting terms in pure gravity;… (More)

We speculate about the spacetime description due to the presence of Lorentzian wormholes (handles in spacetime joining two distant regions or other universes) in quantum gravity. The semiclassical… (More)
