Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

With more than $20 million in contracted mission funding to date, the Quantum Gravity Gradiometer Pathfinder Mission, Led by NASA’s Jet Propulsion Laboratory in Southern California, Advances U.S.

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

A series of theoretical results from some of the field’s most prominent physicists now supports a striking idea: quantum ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Scientists have proposed a new test to hopefully help shed some light on quantum ...

"General relativity is likely incomplete for describing the very first moments of the universe, when quantum effects should also matter." When you purchase through links on our site, we may earn an ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

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 ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

The energy applied by some of the world’s great minds to understand quantum gravity is something to celebrate, but the lack of any real progress in over 100 years implies a gap in the thought ...
