Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of gravity, which explains the behavior of stars, planets, and the structure of the ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Add Yahoo as a preferred source to see more of our stories on Google. For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our ...

The study of quantum gravity seeks a synthesis between quantum mechanics and general relativity, and Causal Dynamical Triangulations (CDT) has emerged as a promising nonperturbative approach. In CDT, ...

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called ...

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 ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...
