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 ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

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 ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is. Reading time 3 minutes The entire spiel of ...
