In physics, the treatment of time is a central issue. In physics, the treatment of time is a central issue. It has been treated as a question of geometry. One can measure time and treat it as a ...

Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace ...

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although we feel as if we ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

Time travel movies have different rules about what happens when you start messing around with the timeline. If you’ve ever wondered which ones make the most sense, we may now have an answer. According ...

In the past, physicist Stephen Hawking has hosted a champagne party for time travelers with balloons and hors d’oeuvres.

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Ronald Mallett, a University of Connecticut physics professor, thinks time travel is possible--and he's designed an experiment that could do it. Basically, he wants to "swirl" empty space the way ...
