Summary: Gravitation and Cosmology
The XXVI Encontro Nacional de Fı́sica de Partı́culas e Campos (ENFPC: Brazilian National Meeting on Particles and Fields) took place in São Lourenço, MG, Brazil, in October 2005. I was invited to deliver the summary talk on the area of gravitation and cosmology, in which I took the opportunity to briefly present a historic sketch of the ideas related to relativity, gravitation and cosmology in ge...
متن کاملGravitation, Experiment and Cosmology *
The confrontation between general relativity (and its theoretically most plausible deviations) and experimental or observational results is summarized. Some discussion is devoted to the various methodologies used in confronting theory and experiment. Both weak-field (solar system) and strong-field (binary pulsar) tests are discussed in detail. A special discussion is devoted to the cosmology of...
متن کاملParticles , Fields , Gravitation , and Cosmology
Rapid Communications are intended for important new results which deserve accelerated publication, and are therefore given priority in editorial processing and production ARa.pid Communication in Physical Review D should be no longer than ftve printed pages and must be accompanied by an abstract. Page proofs are sent to authors, but because of the accelerated schedule, publication is generally ...
متن کاملVarying Constants, Gravitation and Cosmology
Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall. Thus, it is of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We ...
متن کاملGravitation and cosmology in a brane-universe
Recent theoretical developments have generated a strong interest in the “brane-world” picture, which assumes that ordinary matter is trapped in a three-dimensional submanifold, usually called brane, embedded in a higher dimensional space. The purpose of this review is to introduce some basic results concerning gravity in these models and then to present various aspects of the cosmology in a bra...
