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

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 ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

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 ...
