Black Hole Complementarity as a Condition on Pre and Post Selected String States (by Lawrence B. Crowell): Abstract: The holographic principle of black holes tells us the field theoretic information of strings on the event horizon is completely equivalent to field theoretic information in the spacetime one dimension larger outside. This physics is observed on a frame stationary with respect to the black hole. The question naturally arises: what physics is accessed by the observer falling through the event horizon on an inertial frame? This paper examines this and demonstrates a duality between the two perspectives. This question is important for the black hole small enough to exhibit fluctuations comparable to its scale. A sufficiently small quantum black hole will be composed of strings in a superposition of interior and exterior configurations or states. http://prespacetime.com/index.php/pst/article/view/139
Is Einstein Still Misunderstood? (by Amrit S. Sorli): Abstract: Constancy of the light velocity in different inertial systems and areas of space with different gravity implies that relativistic effects of relative velocity of material change start with massive particles. In Special Theory of Relativity and in General Theory of Relativity time t is a numerical order of material change i.e. motion in a 4D space. Time is not part of the space. Time is a numerical order of change that runs in space. http://prespacetime.com/index.php/pst/article/view/140
Plane Symmetric Universe with Wet Dark Fluid in General Relativity (by Shivdas D. Katore, A. Y. Shaikh, M. M. Sancheti, S. A. Bhaskar): Abstract: Plane Symmetric Universe filled with dark energy from a wet dark fluid has been considered. A new equation of state for dark energy component of the Universe has been used. It is modeled on the equation of state p=γ(ρ- ρ) which can describe a liquid, for example water. The exact solution to the corresponding field equations are obtained in quadrature form. The solution for constant deceleration parameter have been studied in detail for both power-law and exponential forms. The cases γ=1 and γ=0 have also been analyzed. http://prespacetime.com/index.php/pst/article/view/129
