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.

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, ...

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 ...

Could it be that the universe’s first structures were born not from enigmatic inflaton fields, but from the echoes of ancient gravitational waves? In a shocking shift from the conventional picture of ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

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 ...
