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 ...

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

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 ...

Physicists have assembled one of the largest and most intricate time crystals yet, using IBM’s latest quantum hardware to ...

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

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

Time’s passage is non-negotiable. Its flow marks the progress of our lives, moving clearly in one direction. It is, by nature, asymmetrical. In this way, we perceive it to move like an arrow, ...

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

Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time When you purchase through links on our site, we may earn an affiliate ...

If a cup of water spills on the floor, the water can’t unspill—that is, it’s inconceivable that each water molecule would exactly reverse its course to slip back into the cup. To do so would be to ...

Physicists have struggled to understand the nature of time since the field began. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Time may not be ...
