Abstract: The conventional view is that the cosmic spectral-redshift, an effect observed in all directions of the heavens, is primarily a measure of space-medium expansion. Significantly, the more distant the galaxy the greater is the redshift — and the greater is the intervening space expansion. The redshift evidence is unequivocal; its implication, its interpretation, however, is not. The important question is this: Does all the evidence for “space” expansion necessarily imply that the whole visible universe must also be expanding? Given a universe whose volume consists mostly of expanding space, does it follow that the entire universe must expand? On this momentous issue rests the future course of cosmology. Yet, it seems, the question has never been seriously addressed. Meanwhile, there is a growing awareness that the assertion of whole-universe expansion is a non-sequitur fallacy. Universe expansion is the unscientific extrapolation of space expansion. It is an unwarranted extrapolation of general relativity. Instead of universal expansion, this paper considers regional space expansion along with regional space contraction — one dynamic process being the complement of the other. This dual dynamic nature of the medium is given full recognition and exploited in the construction of a nonexpanding cellular model of the Universe. The emphasis is on the cell structure and the two “space” postulates involved in sustaining the structure, for it is in the structure of the cosmic cells that the nature of the relationship between Lambda and gravity is revealed.

Abstract: We study the shape of the optical luminosity function of Quasi Stellar Objects (QSOs) from the Sloan Digital Sky Survey Data Release Seven (SDSS DR7) over the redshift range 0.3 ≤ Z ≤ 2.4. By using the Levenberg-Marquardt method of nonlinear least square fit, the observed QSO luminosity function is fitted by a double power-law model with luminosity evolution characterized by a second order polynomial in redshift. For a flat universe with Ωm=0.3 and Ω Λ=0.7, we determine the best-fitting optical luminosity function model parameters.

Abstract: The encounter between Gliese 710 and the solar system is re-examined in light of the newly published parallax and proper motion measurements within the GAIA data 1 release. The up-dated astrometric parameters are found to be significantly different from those implicated by the earlier Hipparcos Catalog and the revised encounter will see GL 710 pass some 5 times closer to the Sun than previously indicated. The closest encounter distance is now found to be 0.064 0.020 pc at a time 1.36 0.12 million years from the present. There is now a 100% certainty that GL 710 will pass through the outer boundary of the Oort cloud, and it will possibly pass as close as 5200 AU to the Sun, indicating the potential for non-negligible gravitational perturbations of those cometary nuclei located close to the inner boundary of the Oort cloud. The revised encounter conditions indicate that a relatively strong cometary shower is likely within the inner solar system, although how this will modify the terrestrial impact probability remains unclear. We find that GL 710 might be expected to capture and accrete several thousands of cometary nuclei as it moves through the Oort cloud, and such impacts can be expected to drive anomalous flare activity. We additionally find that GL 710 will quite likely trigger sublimation-driven outgassing from cometary nuclei situated within a few astronomical units of its path across the Oort cloud.

Abstract: The most important of a long term changes in structure of the atmosphere due to the concentration of various species in the upper atmosphere. The gaseous or vaporous shell that surrounds the earth. When early man first sought to understand his physics environment, his greatest awe surely concerned the sun, moon, planets, and stars (which became the basis of the science of astronomy or astrophysics), and next he wondered at the winds and storms, rain and snom, ironment, his greatest awe surely concerned the sun, moon, planets, and stars (which became the basis of the science of astronomy or astrophysics), and next he wondered at the winds and storms, rain and snow, clouds, lighting, and thunder that collectively made up his weather. The Greek root atmos, meaning air or vapor, originally derived from the word for winds. The first impetus to meteorological theory was given by the puzzling behavior of the barometer in relation to the weather, but it remained for Vilhelm Bjerknes, a physics professor at Bergen, Norway, around 1900 to formulate weather systems mathematically in terms of high- and low-pressure areas, warm fronts, and cold fronts. In England, Napier Shaw began scientific research on atmospheric processes in 1885 at the Cavendish Laboratory, by 1918 weather forecasting had become a science, much as we know it today. So on. As well as the seasonal changes from summer to winter. The prevailing weather at a given location is called its climate, and climate varies with geographical latitude, terrain features, and altitude.
