Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

In 1965, British mathematician Roger Penrose proposed the cosmic censorship conjecture, a concept that suggests that singularities — regions where gravity is so strong that the fabric of spacetime ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Scientists have discovered a new quantum state of matter that connects two significant areas of physics, potentially leading ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...

This ambiguity should give quantum computers true “superpowers”. At least in theory, quantum-based computers can perform calculations in fractions of a second that stump today's best supercomputers.
