whilst predictions of Einstein's concept of common Relativity are in comparison opposed to observations of our Universe, a tremendous inconsistency is located. the most well-liked repair for this inconsistency is to "invent" round ninety four% of the content material of the universe: darkish topic and darkish strength. The darkish power is a few unique substance liable for the plain saw acceleration of the Universe. one other repair is to switch the speculation of gravity: it truly is solely believable that Einstein's idea of basic Relativity breaks down on cosmological scales, simply as Newton's thought of gravity breaks down within the severe gravitational box of the solar. there are numerous replacement theories of gravity, each one with the purpose of describing observations of our Universe the place normal Relativity fails. if it is darkish strength or a few transformed idea of gravity, it truly is transparent that there's a few "dark quarter" within the Universe. during this thesis the writer constructs a unifying framework for figuring out the observational effect of basic sessions of darkish region theories, via formulating equations of country for the darkish area perturbations.

Après ses stupéfiantes avancées du siècle dernier – l. a. découverte de l’expansion de l’univers, du titanic Bang et des trous noirs –, los angeles cosmologie serait-elle en voie de perdre son objet d’étude ? L’avènement de los angeles « matière noire », invisible mais nécessaire pour expliquer les mouvements des galaxies, celui de l’« énergie noire », insaisissable mais essential pour rendre compte de l’accélération de l’expansion de l’univers, et celui des trous noirs, qui font disparaître los angeles matière ordinaire comme un lapin dans un chapeau de magicien, donnent l’image d’un univers élusif dont une half grandissante échappe à l’observation.
