Twin Universes and Bimetric Gravity: From Sakharov's Cosmological Symmetry to Modern Speculations on Negative Mass
Jean-Pierre Luminet
We review the conceptual and theoretical status of twin-universe models, from Sakharov's early ideas on baryogenesis, CPT symmetry, and reversed arrows of time to recent quantum-co…
A Primer on Spacetime Singularities II: Spatially Homogeneous Cosmologies
Jean-Pierre Luminet
This article is the second part of a review devoted to spacetime singularities in classical General Relativity. While Primer I developed the mathematical framework for defining, cl…
A Primer on Spacetime Singularities I: Mathematical Framework
Jean-Pierre Luminet
This article presents a comprehensive and rigorous overview of spacetime singularities within the framework of classical General Relativity. Singularities are defined through the f…
Big Bang Cosmology and Religious Thought
Jean-Pierre Luminet
Alexander Friedmann and Georges Lemaître are undoubtedly the real fathers of Big Bang cosmologies. In this article I study the influences their work underwent due to some religious…
Closed Timelike Curves, Singularities and Causality: A Survey from Gödel to Chronological Protection
Jean-Pierre Luminet
I give a historical survey of the discussions about the existence of closed timelike curves in general relativistic models of the universe, opening the physical possibility of time…
The Dark Matter Enigma
Jean-Pierre Luminet
In this pedestrian approach I give my personal point of view on the various problems posed by dark matter in the universe. After a brief historical overview I discuss the various s…
