As opposed to black holes, white holes are thought to eject matter and light while never absorbing any. Detecting these as yet hypothetical objects could not only provide evidence of quantum gravity...
Launched in 2016, the MICROSCOPE satellite has confirmed with unprecedented precision the equivalence principle, which lies at the heart of Einstein's general theory of relativity. Two...
The initial data gathered by the instrument GRAVITY, for a star near the giant black hole located at the center of our galaxy, confirms the predictions of general relativity in the most extreme...
The Microscope satellite was placed in orbit this April. Its mission: test once more the principle of equivalence, a pillar of the theory of general relativity that postulates that all objects fall...
The Nobel Prize in Physics 2017 has just been awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne for their contribution to the first direct gravitational wave detection as part of the LIGO-...
In order to discover gravitational waves, detectors must be able to distinguish movements as small as one billionth the size of an atom. This major feat of sensitivity has been accomplished and...
