Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Physicists have finally turned a long standing thought experiment into a laboratory reality, showing that electromagnetic ...

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 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 ...

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 ...

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 ...
