Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Albert Einstein’s general theory of relativity does a great job at explaining gravity but it is thought to be incomplete ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

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 ...

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 ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if you analyze the ashes of the fire, the smoke and the flames to re-create ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

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 ...
