Beyond Einstein’s Gravity is a graduate level introduction to extended theories of gravity and cosmology, including variational principles, the weak-field limit, gravitational waves, mathematical tools, exact solutions, as well as cosmological and astrophysical applications.
Our modern understanding of gravity comes from Albert Einstein’s theory of general relativity, which stands as one of the best-tested theories in science. General relativity predicted many phenomena years before they were observed, including black holes , gravitational waves , gravitational lensing , the expansion of the universe , and the ...
4 de sept. de 2024 · Gravity - Fields, Relativity, Theory: In Einstein’s theory of general relativity, the physical consequences of gravitational fields are stated in the following way.
4 de sept. de 2024 · Gravity - Force, Physics, Theory: The Newtonian theory of gravity is based on an assumed force acting between all pairs of bodies—i.e., an action at a distance. When a mass moves, the force acting on other masses had been considered to adjust instantaneously to the new location of the displaced mass.
7 de sept. de 2018 · We discuss a range of metric theories of gravity and their post-Newtonian limits. We begin with a general recipe for calculating the post-Newtonian limit in generic metric theories, and then turn to specific theories.
15 de dic. de 2015 · The gravitational theory of Newton is an extremely good representation of gravity for a host of situations of practical and astronomical interest. It accurately describes the structure of the Earth and the tides raised on it by the Moon and Sun.
24 de abr. de 2019 · In 2015, almost a century after Einstein published the general theory of relativity, one of its most important predictions was verified by direct detection: the production of gravitational waves...
