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 ...

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 ...

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

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 ...

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

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 ...

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

Quantum physicist You Chenglong has returned to China after more than a decade in the United States, taking up a full-time professorship at the University of Electronic Science and Technology of China ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...
