چکیده
Every relativistic particle has 4-speed equal to c, since gμν dx dτ dx dτ = c. With the choice of k = +1 in the FRW metric, the cosmological scale factor a(t) has the natural interpretation of the radius of the sphere S a = {x ∈ R 4 : (x, x) = a}. Thus, a particle at rest in the cosmological frame has 4-speed equal to da dt . This leads us to infer that ȧ = c, which respresents a simple kinematic constraint linking the speed of light to the cosmological scale factor. This drastically changes the k = +1 picture from a closed deaccelerating universe to an open accelerating universe, settles the horizon problem, and provides for a new cosmological model more appealing to our natural intuition. In this paper we shall consider ramifications of this model.

The inclusion of cosmological constant into Einstein field equation was done primarily by Einstein himself with a view to model a static universe. Later he discarded the cosmological constant (and commented [1] “...... the biggest blunder of my life”), on the basis of the observational data supporting the expansion of the universe. Subsequently, it was reintroduced and then omitted to match wit...

A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance scales of the gravitational constant G, the fifth force skew symmetric field coupling strength ω and the mass of the skew symmetric field μ = 1/λ. A fit to the available anomalous acceleration data ...
