Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A physics problem you need to solve! ⚖️🪢 In this video, we break down a classic physics scenario involving two masses attached to a spring, with gravity acting on them. Learn how to approach the ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

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 ...

General relativity and quantum mechanics seem to describe all of observable reality. Between them, general relativity and quantum mechanics seem to describe all of observable reality.

Students learn how mass and distance affect the force of gravity between objects. Gravity: Students learn how mass and distance affect the force of gravity between objects, and how to apply Newton’s ...

I rarely write much about it in my research papers, but every piece of science I have ever done either assumes the correctness of general relativity – our most fundamental theory for explaining ...
