The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It examines how gravity is described by Einstein’s theory at large scales, while ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

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 ...

String theory offers a unified framework in which the fundamental constituents of nature are one-dimensional objects whose vibrational modes give rise to particles and forces. By embedding gravity ...

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 ...

Efforts to unite the principles of quantum mechanics with those of general relativity have given rise to a rich landscape of quantum gravity proposals, including loop quantum gravity, string theory ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

Well, around a similar time, the American Physical Society (APS) invited researchers and science enthusiasts to chime in on 10 broad questions on major concepts—of arguable contention—in physics as a ...
