Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other ...

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

An international team of astronomers has conducted a new test of Albert Einstein's famous theory of general relativity (GR), finding that it works even in extreme gravitational environments, according ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

Scientists are trying to figure out to what extent a new theory of quantum gravity will reproduce general relativity. Scientists at Texas A&M University in the US explore this question in a paper ...
