The question about the relation between spacetime structure and the symmetries of laws has received renewed attention in a recent discussion about the status of Minkowski spacetime in Special Relativity. In that context we find two extreme positions (eith... see more

The Randall-Sundrum solution to the hierarchy problem in the brane-world scenario has made a significant impact on the development of model building.We investigate in this paper a model of supersymmetry in a 5D spacetime with the Randal-Sundrum warped met... see more

A phenomenological interpretation of home is usually done romantically, in which the home is thought to be a source of safety, comfort, and security. This conclusion about home is problematic, considering that if all of these components do not exist in a ... see more

In response to the Vieques 2014 FQXi Conference on the Physics of Information (http://fqxi.org/conference/2014), this colloquium brings together over a dozen neuroscientists, physicists and medical researchers to provide a body of empirical data both supp... see more

The Minkowsiki spacetime is flat and there is no source of gravitation. The time conformal factor is adding some cuvature to this spacetime which introduces some source of gravitation to the spacetime. For the Minkowski spacetime the Einstein Field equati... see more

Cet article présente et discute, d'un point de vue épistémologique, une théorie quantique de l'espace-temps basée sur des principes formés à partir de la mathématique infinie appliquée à la philosophie naturelle, de la cosmologie et de la géométrie rieman... see more

The object of the present paper is to introduce spacetimes with pseudosymmetricenergy-momentum tensor. In this paper at first we consider the relation R(X,Y)·T=fQ(g,T)R(X,Y)\cdot T=fQ(g,T), that is, the energy-momentumtensor TT of type (0,2) is pseudosymm... see more

In this paper, starting from the common foundation of Connes' noncommutative geometry ( NCG)\cite{Connes1, Connes2, CoLo, Connes3}, various possible alternatives in the formulation of atheory of gravity in noncommutative spacetime are discussed indetails.... see more

This article is a logical analysis of historical records and reaches conclusions that are original.Prior to 1905 it was generally believed that the universe had always existed. The exact age of Earth was not known.The luminiferous æther theory explained h... see more
