Gravitational physics

Physics World, 1996
Gravity is truly universal. It is the force that pulls us to the Earth, that keeps the planets and moons in their orbits, and that causes the tides on the Earth to ebb and flow. It even keeps the Sun shining. Yet on a laboratory scale gravity is extremely weak.

Einstein and Beyond: A Critical Perspective on General Relativity

, 2016
An alternative approach to Einstein's theory of General Relativity (GR) is reviewed, which is motivated by a range of serious theoretical issues inflicting the theory, such as the cosmological constant problem, presence of non-Machian solutions, problems

Teoria quântica da gravitação: cordas e teoria M

Revista Brasileira de Ensino de Física
Discutimos aqui a junção da relatividade geral e da mecânica quântica como necessidade tanto teórica quanto experimental da Física, e suas conseqüências na compreensão do Universo, de seu início e sua evolução.

Extended Theories of Gravitation

EPJ Web of Conferences, 2013
Extended theories of gravitation are naturally singled out by an analysis inspired by the Ehelers-Pirani-Schild framework. In this framework the structure of spacetime is described by a Weyl geometry which is enforced by dynamics.

Gravitation and Electromagnetism

, 2016
The realms of gravitation, belonging to Classical Physics, and Electromagnetism, belonging to the Theory of the Electron and Quantum Mechanics have remained apart as two separate pillars, inspite of a century of effort by Physicists to reconcile them. In

Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations

Astronomy & Astrophysics
We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the significantly enhanced (u,v) coverage in the 2021 Event Horizon Telescope (EHT) observations.

Exotic matter and MOND as special cases of a more general solution in pure general relativity

Frontiers in Astronomy and Space Sciences
Several solutions have been proposed to explain the dark matter (DM) component, but two explanations stand out. The most widely accepted is the assumption of the existence of exotic matter, and the second is the assumption of a modification of ...

Finite-Range Scalar–Tensor Gravity: Constraints from Cosmology and Galaxy Dynamics

Galaxies
Objective: We examine whether a finite-range scalar–tensor modification of gravity can be simultaneously compatible with cosmological background data, galaxy rotation curves, and local/astrophysical consistency tests, while satisfying the luminal ...
