Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. A radical theory that consistently unifies gravity and quantum mechanics while ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

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 ...
