Scientists confirm that clocks on Mars run faster than on Earth and will change global space navigation in the future ...

The Trump administration on Thursday revoked a scientific finding that climate change is a danger to public health, an idea ...

After defying gravity for much of the past few years, Palantir Technologies ( PLTR +1.71%) is finally coming back to earth, with the stock falling as much as 6.7% on Thursday. As of 2:00 p.m. ET, the ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Sagittarius A* may be a dense dark matter core instead of a black hole, offering a new explanation for the Milky Way’s central gravity.

Infleqtion, a global leader in quantum sensing and quantum computing powered by neutral-atom technology, announced its role as a collaborator on NASA’s Quantum Gravity Gradiometer Pathfinder (QGGPf) ...

Infleqtion’s NASA quantum gravity sensor launch for 2030 and SPAC deal with Churchill X (CCCX) could move INFQ—get the latest quantum stock update.

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...
