Unraveling the cosmic symphony of gravitational waves, from the 'Music of the Spheres' to moon-based detectors.

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...

New observations of two black holes merging have confirmed predictions made decades ago by Albert Einstein, Stephen Hawking, ...

Einstein’s uncle Jakob was an inventor in Munich. He produced patents for arc lamps, electric meters, and dynamos in the late ...

A newly observed black hole collision has provided scientists with the clearest view yet of one of the universe’s most ...

We previously covered one such “gravity telescope” with the Laser Interferometer Gravitational-Wave Observatory (LIGO). Another one is the Japanese project Kamioka Gravitational Wave Detector (KAGRA).

A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The id ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...
