Abstract: This study explores the complex interplay between entropy and human behaviour in the context of spacetime. Itseeks to investigate the broad and interwoven impact of human action on the entropy of the universe at the individual andsocietal levels by fusing ideas from thermodynamics, physics, and social sciences. The goal of this multidisciplinary study is to offer a comprehensive and sophisticated knowledge of the intricate interactions that occur between human behaviour and spacetime’s changing dynamics.

Dark Matter is Just Gravity, Only Normal Matter is the truth Dark Matter is Just Gravity

Sandeep S. Jaiswal, University of Alabama in Huntsville, 301 Sparkman Drive, Huntsville, AL 35899.

Abstract: All the major observational evidences available so far for the existence of dark matter can be explained by simple physical equations and derived astronomical data proving that dark matter theory is wrong. Furthermore, the normal matter is the only matter this is causing all the phenomena’s to happen that was previously believed to be due to unexplained dark matter. New general laws of physics for galactical rotation that cannot be explained by Kepler’s law alone is also derived.

Keywords: Dark matter; Normal baryonic matter; Gravity

Abstract: The quantum properties of a non-degenerate three-level laser with the parametric amplifier and coupled to a thermal reservoir are thoroughly analyzed with the use of the pertinent master equation and stochastic differential equations associated with the normal ordering. Applying solutions of resulting differential equations, quadrature variance, the mean and variance of photon number, the photon number correlation are calculated. However, the two-mode driving light has no effect on the squeezing properties of the cavity modes. Employing the same solutions, one can also obtain anti normally ordered characteristic function defined in the Heisenberg picture. For a linear gain coefficient of (A = 100), for a cavity damping constant of K= 0:8, μ = 0.16 and for thermal reservoir nth = 0, the maximum intra cavity photon entanglement is found at steady state and at threshold to be 70%.
