Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already ...

Quantum computers are still a work in progress but quantum sensors are already in use at hospitals, laboratories and by ...

On July 28, 2019, the LIGO and Virgo gravitational-wave observatories recorded a brief shudder in spacetime: two black holes, ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

It does not resolve the discrepancy, but it gives physicists one more data point in their ongoing quest to nail down a more precise value for Big G. Isaac Newton introduced the concept of a ...

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. But scientists have only tuned into ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and ...

Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. These anomalies are fluctuations in gravity, and while they were suspected to ...

With $20 M funding so far, Quantum Gravity Gradiometer Pathfinder Mission is intended to “advance U.S. space sensing”. 16 February 2026 Red indicates areas of the world that exert greater ...
