Gravitational wave - Wikipedia
Web3 days ago · 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. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the ...

Study: Experiments That Could Show Gravity's ... - ScienceAlert
Web4 days ago · 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.
First proof that “plunging regions” exist around black holes in space
Web3 days ago · An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein’s theory of gravity, their study gives the first observational proof that a “plunging-region” exists around black holes: an area where matter stops circling ...
