Solar System Tests of Higher-Dimensional Gravity
The classical tests of general relativity — light deflection, time delay and perihelion shift — are applied, along with the geodetic precession test, to the five-dimensional extension of the theory known as Kaluza-Klein gravity, using an analogue of the four-dimensional Schwarzschild metric. The perihelion advance and geodetic precession calculations are generalized for the first time to situat...
متن کاملSolar System tests of Hořava–Lifshitz gravity
In the present paper, we consider the possibility of observationally constraining Hořava gravity at the scale of the Solar System, by considering the classical tests of general relativity (perihelion precession of the planet Mercury, deflection of light by the Sun and the radar echo delay) for the spherically symmetric black hole Kehagias– Sfetsos solution of Hořava–Lifshitz gravity. All these ...
متن کاملSolar system tests do rule out 1=R gravity
Shortly after the addition of a 1=R term to the Einstein-Hilbert action was proposed as a solution to the cosmic-acceleration puzzle, Chiba showed that such a theory violates Solar System tests of gravity. A flurry of recent papers have called Chiba’s result into question. They argue that the spherically-symmetric vacuum spacetime in this theory is the Schwarzschild-de Sitter solution, making t...
متن کاملComparing Solar - System , Binary - Pulsar , and Gravitational - Wave Tests of Gravity
This talk is based on my work in collaboration with Thibault Damour. We compare the probing power of different classes of gravity experiments: solar-system tests (weak-field regime), binary-pulsar tests (strong-field regime), and future gravitational-wave observations of inspi-ralling binaries (strong-field effects detected in our weak-gravitational-field conditions). This is done within the mo...
متن کاملSolar system tests of the cosmological constant
— We discuss the influence of the cosmological constant Λ on the gravitational equations of motion of bodies with arbitrary masses and eventually solve the two-body problem. Observational constraints are derived from measurements of the periastron advance in stellar systems, in particular binary pulsars and the solar system. For the latter we consider also the change in the mean motion due to Λ...
