To most of us, time feels as solid as the phone alarm that drags us out of bed or the calendar that fills up faster than we ...

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

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

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

Imagine traveling through a city where the streets themselves change shape depending on how fast you drive down them. For ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...
