The tired-light interpretation of the cosmological redshift is as old as the discovery of the phenomenon itself, and a number of mechanisms have been proposed by researchers in cosmology. This article presents the basic ideas behind the author's recent proposal of an inertial induction model consisting of both velocity-and acceleration-dependent terms which can explain the cosmological redshift...

We examine the traffic lights regime to enable the fastest overall approach to a city for a specific case. The case involves a traffic light where one continues on the main road, into which additional cars are entering at the light. At this intersection an alternative route begins, which is longer but into which no additional cars are entering. To keep the total number of vehicles constant, we ...

We have studied modulated inflation that generates curvature perturbation from light-field fluctuation. As discussed in previous works, even if the fluctuation of the inflaton itself does not generate the curvature perturbation at the horizon crossing, fluctuation of a light field may induce fluctuation for the end-line of inflation and this may lead to generation of cosmological perturbation “...

Due to the breakthrough of laser cooling techniques during the last 10 years it is nowadays possible to produce samples of cold atoms with sufficient density to study collisional processes. This has lead to the exploration of a new field of (ultra-)cold collisions. Especially the study of cold collisions in the presence of a light field has been very successful. Three aspects have played a majo...

Accelerated and decelerated motions of a charged point particle inside medium are studied. It is shown explicitly that in addition to the bremsstrahlung and Cerenkov singular waves, previously unknown electromagnetic singular wave should be observed. It arises when the charge velocity coincides with the light velocity in medium. This wave has the same singularity as the Cerenkov one and, theref...

We calculate the screening potential of a fast parton moving through a quark-gluon plasma in the framework of semi-classical transport theory. We found an anisotropic potential showing a minimum in the direction of the parton velocity. Possible consequences of this potential on binary states in a quark-gluon plasma are discussed. Screening of charges in a plasma is an important collective effec...

We report experimental values of the group velocity dispersion (GVD) of water and methanol at 800 nm. We find GVD 800 = (25.71± 0.5) fs 2mm−1 and GVD 800 = (33.56± 0.5) fs mm−1. These were measured by sending 50 fs, 800 nm pulses with various amounts of chirp through a glass cell filled with a solution of fluorescein in these solvents and recording the production of visible light from the side ...

The Ca2+ dependence of the kinetics and light sensitivity of light-activated phosphodiesterase was studied with a pH assay in toad and bovine rod disk membranes (RDM), and in a reconstituted system containing GTP-binding protein, phosphodiesterase and rhodopsin kinase. Three statistics, peak hydrolytic velocity, turnoff time, and time to peak velocity, were measured. ATP decreased phosphodieste...

A corollary of general relativity that the velocity of light is anisotropic in a gravitational field has received little attention so far. It is shown that this anisotropy can be directly probed by an experiment initially proposed for testing the one-way velocity of light. The proposed experiment constitutes another test of general relativity since the anisotropy in the propagation of light in ...
