    Abstract: This paper is the theory for the speed of gravitational waves and comparison of it with the speed of light. The GW (Gravitational Waves) have been observed [1] and the role of dark energy and cold dark matter are being studied [2, 3], but the key role of gravitational waves speed in the stability of cosmic formations has not been studied much.

    Abstract: The intensities observed along nadiar at the top of atmosphere as a function of solar zenith angle for ƛ = 0.55 micron, haze o refractive index m = 1.50 – 0.031 and aerosols distributed over 0.03 to 10 micron range. As the solar zenith angle increases, the increases in effective atmosphericpath leads to decrease in intensity – approaching to zero a... Show More
