A new theory proposed by researchers at the Stevens Institute of Technology, Colorado State ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Ultraprecise atomic clocks could test the idea that time moves at multiple speeds.

Atomic clocks are already precise enough to measure tiny effects of relativity, such as time dilation; for example, if you ...

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 ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model ...

A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

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 ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...
