Abstract: The numbers of photons per second for more than a year (2013-2014) recorded every ~2.5 s by a digital photomultiplier unit was maximum during August to October and minimum during February through April. The peak-to-peak difference in quantity for the classical, smooth variation was 2.4 x 10-12 W m-2. This value is within the order of magnitude for a photon source from the galactic center with a power of 1059 J from a spherical surface with a radius defined for a singularity that could be equivalent to the galactic mass. The calculated change in photon flux density from such a source for the annual change in the earth’s distance around the sun relative to the distance to galactic center was ~10-21 W m-2 or equivalent to 10 Solar Flux Units (SFU). Data obtained for daily SFU for the years 2009 through 2013 indicated that an average difference was 8 to 10 SFU higher for September-October when the earth would be closer to the galactic center than March-April. The most likely source of the amplitude of the annual variation is consistent with modification by the earth’s position in the solar mass field with respect to the galactic center. These data suggest that at least a subset set of background photon emissions on the earth’s surface display a clear annual variation whose source could originate from a singularity at the distance of the center of the Milky Way.Abstract: The numbers of photons per second for more than a year (2013-2014) recorded every ~2.5 s by a digital photomultiplier unit was maximum during August to October and minimum during February through April.

Abstract: In this paper discussing about the mathematical aspect of variables such as cosmological constant (Λ) and gravitational constant (G) under some suitable assumptions, G(t)=F exp(3Hγt) (where is constant and γ is equation of state parameter), and the cosmological constant. Λ∞t-2 The exact solutions for the field equations and discuss some physical properties of the cosmological model. An expanding universe is found by using a relation between Friedmann equation and an equation of state. The cosmological constant has been involved on several occasions to correct some seemingly real difficulty with the cosmological predictions of standard general relativity. The most notable of these where its initial use by Einstein to produce static universe. The physical situation regarding is unclear. The other cosmological parameters Hubble constant (H), the density parameter (ρ), Gravitational constant (G) etc, may not constant at all. In this work emphasize to investigate these constants vary with time.Abstract: In this paper discussing about the mathematical aspect of variables such as cosmological constant (Λ) and gravitational constant (G) under some suitable assumptions, G(t)=F exp(3Hγt) (where is constant and γ is equation of state parameter), and the cosmological constant.
