Arecibo - an astounding legacy
... observed in the periastron of the binary system – the point of closest approach - led to the first indirect evidence of gravitational waves. The first radar ranging of an Earth-crossing asteroid, 1862 Apollo, was done in 1980 and, a year later...

Does the speed of light change with time?
... are popular and many different versions of the theory have been put forward, including a publicised announcement of gravitational waves from ‘inflation’ in 2014, which turned out to be due to cosmic dust. But the drawback with inflation is that...

Ring of fire around black hole revealed for first time
... abyss of the black hole still remained elusive. Even before that, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves emanating from the merger of two black holes. These ripples in the curvature of spacetime...
