The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

When the plasma physics community gathers for its biggest annual event, the Princeton Plasma Physics Laboratory (PPPL) shows up in force. This year's ...

Pulsars are some of the most reliable metronomes in the universe, and scientists are now using their flickering radio beams to keep time across the galaxy and sharpen the search for intelligent life.

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

When humans think about time, most imagine a steady flow of seconds ticking into minutes and minutes into hours which carry us from past to present to future. But in the science of quantum physics, ...

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...

Imaginary time is a wonky concept for our time-bound brains, but in quantum theory and mathematics, it’s a useful tool for exploring radiation's interaction with materials. A new study from scientists ...

Researchers demonstrate a novel method for transforming continuous time crystals into discrete ones using subharmonic injection locking, offering new insights into symmetry breaking and control in ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

A time-to-digital converter (TDC) is like a stopwatch measuring the elapsed interval between two events with picosecond precision, converting this into a digital value for post-processing. Many space ...
