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

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 ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

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 ...

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

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

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...
