Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

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 ...

The universe’s first moments after the Big Bang were strange beyond imagination. Now physicists have discovered they may have been even weirder than we thought, dominated by enormous, twisted knots of ...

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 ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

The Big Bang refers to that gigantic explosion responsible for setting up the universe to grow into the world we observe ...
