Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Robert Oppenheimer’s greatest contribution to physics was one that he wanted nothing to do with for the rest of his life. In 1939 Oppenheimer and his student Hartland Snyder published a paper in the ...

Physics provides the fundamental rules that govern our universe — or so we thought. Throughout history, brilliant minds have uncovered phenomena that shattered our understanding of reality, forcing us ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

A centuries-old fundamental law of physics called the principle of least action has been demonstrated using quantum objects for the first time. “A physicist’s ultimate dream is to write the secrets of ...

Studying physics can be very useful—even when it comes to machine learning. A digital "super-brain" with built-in knowledge ...

Researchers at Chalmers University of Technology have developed a machine learning system that learns ...

Throw a pebble into a lake and it, obligingly, sinks. Smash particles together and they fall apart in certain patterns. Flick a switch and let there be light. Reality, for all its glory and cosmic ...

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, ...

For the first time, scientists have created oxygen-28, a rare oxygen isotope that has 12 more neutrons than oxygen-16, the most common form of oxygen on the planet. This newly created "heavy" oxygen ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
