AALTO, Finland — Scientists have potentially solved what many consider physics’ most challenging problem – reconciling Einstein’s theory of gravity with quantum mechanics, without adding any new ...

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 ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have stubbornly resisted every attempt to bring them under one roof. A new geodesic-based ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

General relativity and quantum mechanics seem to describe all of observable reality. Between them, general relativity and quantum mechanics seem to describe all of observable reality.
