Can negative mass be considered in General Relativity ?
Jean-Pierre Petit, Gilles dAgostini
We show, through Newtonian approximation, that shifting to a bimetric model of the Universe based on a suitable system of coupled field equations, removes the preposterous runaway…
Five Dimensional bigravity. New topological description of the Universe
Jean Pierre Petit, Gilles d'Agostini
We extend the bimetric description of the Universe to a five-dimensional framework. Starting from Souriau's work (1964) we use two Robertson-Walker metrics with an extra term corre…
Bigravity: a bimetric model of the Universe with variable constants, inluding VSL (variable speed of light)
Jean Pierre Petit, Gilles d'Agostini
The Universe, far to be homogenous, expands in large empty bubbles of the large-scale structure, but not in mass concentrations like galaxies, so that the Robertson-Walker solution…
Bigravity : A bimetric model of the Universe. Positive and negative gravitational lensings
Jean-Pierre Petit, Gilles d'Agostini
After a short summary of our bimetric model of the Universe, an exact nonlinear solution is built, which demonstrates the existence of solutions for our two coupled field equations…
Bigravity as an interpretation of the cosmic acceleration
Jean-Pierre Petit, Gilles D'Agostini
A bimetric description of the universe is proposed, which explains cosmic acceleration deduced from optically observed high-redshift objects. This phenomenon is classically charged…
I - Matter, antimatter and geometry II - The twin universe model : a solution to the problem of negative energy particles III - The twin universe model plus electric charges and matter-antimatter symmetry
Frederic Henry-Couannier, Gilles D'Agostini, Jean-Pierre Petit
We introduce a new dynamical group whose coadjoint action on its momentum space takes account of matter-antimatter symmetry on pure geometrical grounds. According to this descripti…
