A little more than a year ago, humanity got its first good look at the most mysterious object of the vast universe. For the first time, astronomers had imaged a black hole, which was lurking on the ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Physicists in the US have used a tabletop experiment to rule out the existence of strong, gravitational-like forces at short length scales. Such forces, which could hint at additional space–time ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

On April 20, a satellite conceived in the 1960s to test two aspects of Einstein’s general theory of relativity finally roared into space from Vandenberg Air Force Base in California. Aside from two ...

A team led by astronomer Margot Brouwer (Leiden Observatory, The Netherlands) has tested the new theory of theoretical physicist Erik Verlinde (University of Amsterdam) for the first time through the ...
