Testing Dark Energy and Cardassian Expansion for Causality
J. Ponce de Leon
Causality principle is a powerful criterion that allows us to discriminate between what is possible or not. In this paper we study the transition from decelerated to accelerated ex…
Electromagnetic mass-models in general relativity reexamined
J. Ponce de Leon
The problem of constructing a model of an extended charged particle within the context of general relativity has a long and distinguished history. The distinctive feature of these…
Inevitability of Spacetime Singularities in The Canonical Metric
J. Ponce de Leon
We discuss the question of whether the existence of singularities is an intrinsic property of 4D spacetime. Our hypothesis is that singularities in 4D are induced by the separation…
Equations of Motion in Kaluza-Klein Gravity Revisited
J. Ponce de Leon
We discuss the equations of motion of test particles for a version of Kaluza-Klein theory where the cylinder condition is not imposed. The metric tensor of the five-dimensional man…
