Abstract: Classical equation for space time and matter gives the relation between a mass and the space time surrounded by its space time fluid. Mass of the basic building block of matter creation has been termed as ‘K-Suryon’. Mass of ‘K-Suryon’ has been calculated as 1.15x10-64 kgs. The density of its space time fluid is calculated as 3.32x10626 Kg/cum. Thus ‘K-Suryon’ is the most elementary mass that can exist in this universe. We know the minimum mass of anybody to become black hole is ‘Chandrasekhar’s Limit’ .For that mass we can calculate the space time fluid density. So we can find the density of space time fluid associated with it. With these calculations we have concluded that the physical singularity will not be there for a black hole. A physical singularity will exist below a critical density equal to K-Suryon where space time will not exist. It is concluded that velocity of light is reducing and space time fluid density of universe is increasing with the age of Universe. Experimental verification may be possible.

Abstract: The present paper derives an expression for the change in internal energy and enthalpy of the black holes using first law of thermodynamics and showing that the change in internal energy and enthalpy are the manifestations of same thing at constant pressure and volume. The paper also shows that the spinning black holes with spin a*→1 do not radiate energy and mass of the black hole becomes infinity for zero surface gravity.

Abstract: Ever since the discovery of Libyan Desert Glass in the southwest corner of the Great Sand Sea near the Libyan border, its source of formation has become the subject of controversy that still has not been resolve. This paper introduces a general description of Libyan Desert Glass. It presents briefly different theories explaining its formation. This paper introduces also new interpretation for Libyan Desert Glass formation. This interpretation suggests a meteorite impact mechanism. In this paper, the study of meteorite impact mechanism of BP and Oasis craters was carried out for the first time using a simple model. Calculations have shown that change in temperature for the target materials (sand) because of meteorite impact could explain the formation mechanism of Libyan Desert Glass that took place about 29 million years ago.

Abstract: Type II and Type III bursts are probably the most intensively studied form of radio emission in all of astrophysics. Immense effort has gone into the elucidation of both the observational and theoretical aspects. The bursts have captured the attention of plasma theorists because a considerable body of information exists on the plasma parameters and because there is adequate space and time in the solar corona for the evolution of various particle and wave processes. In our work, we have studied the type II bursts and their association with type III bursts during the increasing phase approaching the peak phase of solar cycle 23. For the period 2000-2001, type III bursts data of Culgoora observatory is referred. The parameters such as duration drift rate, shock speed, band width of these associated/non associated bursts are compared .Results indicate that the above parameters almost remain uniform for associated and non-associated type II bursts.

Abstract: In the present research work, we calculate the frequencies of Hawking radiations emitted from different test black holes existing in X-ray binaries (XRBs) and active galactic nuclei (AGN) by utilizing the proposed formula for the frequency of Hawking radiation f=8.037x1033kg/M(HZ)and show that these frequencies of Hawking radiations may be the components of electromagnetic spectrum and gravitational waves. We also extend this work to convert the frequency of Hawking radiation in terms of the mass of the sun (Mo)and then of Chandrasekhar limit (Mch), which is the largest unit of mass.

Abstract: Neeraj Pant et al.(2010) gave a detailed study of BCT First solution (Tewari,1988) representing time dependent balls of perfect fluid with matter-radiation in general relativity to assume the life time of quasar 107 years, initial mass≈108M with an initial linear dimension≈1015 cm are radiating energy at a constant rate i.e. L∞=1047 ergs/sec with the gravitational red shift, z=0.44637. For quasars with LQSO~1046erg/sec, the black hole masses in those systems must be at least 108 solar masses (Astro 3830: Spring 2004). In the present work, we have calculated the radiative efficiency of black holes existing in AGN by using the formula L/Mc2 (Narayan2005, Xie & Yuan 2012) and compared our results regarding some characteristics of super massive black holes with some other works given in references like Astro 3830:Spring (2004), Narayan (2005), Xie & Yuan (2012) and Chan (2013) and concluded that the mass of black holes never be greater than 5×109 M⊙ as well as the radiative efficiency of black hole is smaller than the same mass of quasars.
