... With above definitions, the following is obtained: Let t be a tangent vector field with only positive coordinates (in coordinate systems in the standard spacetime atlas). Then there is a unique connection d, such that d (t, t) = 0 for all such t. In particular and roughly speaking, d-shifting the ve ...

Large Extra Dimensions - Are you sure you want to look at this?
... around one another all provide evidence that suggests there are (3 + 1) dimensions. With all of this evidence pointing to (3 + 1) dimensions, why would anyone want to propose that there existed additional dimensions? One such motivation was unification. In 1921, Theodor Kaluza discovered that if gen ...

Introducing surface tension to spacetime
... Figure 1. Geometry of an arbitrary matter distribution in a small volume of spacetime displaying membrane-like properties Consider the same matter distribution from a relativistic perspective. At the start of most physics problems/experiments, clocks are typically set to zero. At the instant clocks ...

Gravitoelectromagnetism (GEM): A Group
... During the last twenty years, several formalisms of GEM, including covariant and non-covariant treatments, have been developed within the framework of general relativity [35] and of the Maxwellian gravity in Minkowski space-time [36]. As we can notice many formulations of GEM, based on different fra ...

An action principle in general relativistic
... Notations and a precise definition of variations are given in the remainder of this section. Although no new material, we have recalled in section 2 some features of the conservation of gravitational energymomentum. Section 3 deals with electromagnetic fields in matter and how one can introduce thes ...
