Hace 4 días · Gravitational waves are propagating disturbances in the curvature of spacetime, caused by some of the most violent and energetic physical processes in the universe. A common analogy in general relativity considers gravity to be caused by masses warping a rubber sheet; smaller masses …
Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies, and even light and sub-atomic particles.
Hace 4 días · This is a list of most likely gravitationally rounded objects (GRO) of the Solar System, which are objects that have a rounded, ellipsoidal shape due to their own gravity (but are not necessarily in hydrostatic equilibrium).
Hace 1 día · Definition and basic properties [ edit] General relativity is a metric theory of gravitation. At its core are Einstein's equations, which describe the relation between the geometry of a four-dimensional pseudo-Riemannian manifold representing spacetime, and the energy–momentum contained in that spacetime.

Hace 5 días · Using the ``composite harmonic mapping method,"we construct exact solutions for cylindrically symmetric gravitational and electromagnetic waves within the Einstein-Maxwell system, focusing on the conversion dynamics between these types of waves. In this approach, we employs two types of geodesic surfaces in ${\mathbb H}^{2}_{C}$: (a) the complex line and (b) the totally real Lagrangian plane ...
Hace 5 días · Violation of Lorentz symmetry can result in two distinct effects in the propagation of the gravitational waves (GWs). One is a modified dispersion relation and another is a frequency-dependent damping of GWs. While the former has been extensively studied in the literature, in this paper we concentrate on the frequency-dependent damping effect that arises from several specific Lorentz-violating ...
Hace 2 días · Our investigation focuses on the emission of gravitational radiation from six rapidly spinning WDs: five of them are situated within binary systems, while one is an AXP, proposed as a magnetic accreting WD.
