A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

A second image of the first black hole ever pictured by humanity, the supermassive black hole in M87, taken one year later shows its shadow persists just as Einstein predicted.

The obtained images clearly show an apparent rotation of the objects, thus confirming the theoretical predictions. Peter Schattschneider and his team combined images taken at different moments to ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

Albert Einstein. The theoretical physicist published his theory of general relativity in 1919. Lucien Aigner/The Image Bank Unreleased. In their study, the researchers used data from the Dark ...

The images were then combined to include only those where each object is illuminated by the laser at the moment when light would have been emitted if the speed of light were only two meters per ...

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s ...

A splashy California-based launch company named Relativity Space shared a photo of sleek-looking rocket hardware on its social media channels last week. The image featured an impressively large ...
