Hace 1 día · General relativity. Gravitational waves are waves of the intensity of gravity that are generated by the accelerated masses of binary stars and other motions of gravitating masses, and propagate as waves outward from their source at the speed of light.
Hace 3 días · 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 3 días · Alternatives to general relativity. Alternatives to general relativity are physical theories that attempt to describe the phenomenon of gravitation in competition with Einstein's theory of general relativity. There have been many different attempts at constructing an ideal theory of gravity. [1]
Hace 1 día · The Sun is the star at the center of the Solar System.It is a massive, hot ball of plasma, inflated and heated by energy produced by nuclear fusion reactions in its core. Part of this energy is emitted from its surface as visible light, ultraviolet, and infrared radiation, providing most of the energy for life on Earth.The Sun has been an object of veneration in many cultures.
A gravitational field is a region within which an object is acted on by a gravitational force. The mass of any object produces a gravitational field, but for objects on Earth, the forces due to their gravitational fields are sufficiently small that they are approximately zero.
Hace 5 días · Now, a team of physicists from the Netherlands and Germany claim they have devised the very experiments that could reveal whether gravity is fundamentally a quantum force, its properties shaped at the smallest possible scales, or a classical one, geometric like Einstein envisaged.
Hace 5 días · Gravitation, one of the fundamental forces of nature, plays a remarkable role in shaping the universe as we know it. From the way objects fall to the motion of celestial bodies, gravity is at the core of these phenomena. But did you know that there is more to gravitation than meets the eye?
