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 ...

A new study shows that slow, deep rock currents inside the Earth have helped shape the planet's strongest large-scale ...

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 ...

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 ...

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 ...
