Abstract
A bimetric description of the universe is proposed, which explains cosmic acceleration deduced from optically observed high-redshift objects. This phenomenon is classically charged to a mysterious repulsive "dark energy" whose true nature is unknown. This is identified in this model with a set of particles having negative mass and energy. These negative mass particles, emitting negative energy photons, are not observable using optical instruments.
Looks like the rest of the world is about to catch up with Jean-Pierre Petit's theories about negative masses surrounding positive mass objects like galaxies and holding them together... Even the proposal for the modification of Einstein's theories... Times are a'changin. It…
