A frozen continent at the bottom of the world sits over the deepest dip in Earth’s gravitational pull, a feature that has persisted for roughly 70 million years. Scientists have long known about this ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

Infleqtion, a Boulder-based quantum-technology company, said this week that it “will fly the first quantum sensor capable of measuring the Earth's gravitational field and its gradients” as part of ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

In an ambitious new proposal, scientists suggest that humanity could soon turn the Sun into a colossal telescope, allowing us to observe distant cosmic objects in ways never before possible. By ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

The study of relativistic effects in gravitational fields remains at the forefront of physics research, refining our comprehension of space‐time and its intricate interplay with matter. Notably, ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

On March 17, 2002, the German-US satellite duo GRACE (Gravity Recovery and Climate Experiment) were launched to map the global gravitational field with unprecedented precision. After all, the mission ...
