A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Vijay Balasubramanian (University of Pennsylvania) emphasised that the challenge is not only reproducing the familiar area law – which links entropy to the area of the event horizon – but also ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our two best bets on understanding the universe on a macroscopic and ...

Quantum gravity is a research area in theoretical physics that seeks a consistent, predictive framework unifying general relativity with quantum mechanics by quantizing the gravitational field. It ...

With more than $20 million in contracted mission funding to date, the Quantum Gravity Gradiometer Pathfinder Mission, Led by NASA’s Jet Propulsion Laboratory in Southern California, Advances U.S.

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally ...

Root, an Assistant Professor at Delft University of Technology, investigates the significance of quantum satellite gravimetry in this intriguing analysis ...
