There has been much speculation that the Schwarzschild field harbors regions of gravitational repulsion, witnessed by a positive acceleration. The criterion is that the radial velocity should be...

These 'entropies' depend upon a parameter, which can be varied between two limits. In those limits they reduce to the Shannon-Gibbs and Hartley-Boltzmann entropies. If such entropies did exist...

It is impossible that the radial distance between any two points be greater than their difference. Also the appeal to Newton's law at large distances and a weak field forms part of the concept of...

If quantum mechanics requires the singlevaluedness of the wave function as a solution to the Schroedinger equation, how can it possibly explain the multivaluedness of the phase in the ESAB effect?...

The thermal equation of state p=w e, where w is the ratio of the pressure, p, to the internal energy density, e, would identify it as the latter. If that were the case w would vary between 1/3 for...

The conclusion is based upon a look-a-like appearance between the frequency spectrum of an exponential frequency shift due to acceleration. Although the frequency shift should be due to a uniform...

The zero-divergence property of the Einstein field equation gives the condition for an adiabatic expansion. Hence there can be no entropy increase due to reheating at the end of the inflationary...
