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 ...

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 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Time may not be a fundamental element of the universe but rather an illusion emerging from quantum entanglement, a new study suggests. Time is a thorny problem for physicists; its inconsistent ...

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

The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Physicists have described using quantum entanglement to ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.
