Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

An international team of researchers has found a simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. An ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

In an effort to solve the riddle of why we have subjective conciousness, scientists have develop myriad theories, including ones involving the quantum realm. A new theory suggests that consciousness ...

A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity. Before Erwin Schrödinger’s cat was ...

For a long time, quantum computing remained in the realm of theory or developed only in limited environments. In its early stages, it depended on crea ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...
