Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

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 ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? If neutrinos were Diet Coke, we’d say they have “0 calories” of mass—nearly none.

Researchers at the Indian Institute of Technology Bombay have proposed a new test to measure the “quantumness” of gravity after finding that conventional “quantum entanglement-based” tests may be ...
