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 ...

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 ...

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 ...

Traditionally, we think of the universe as being made up of three spatial dimensions, and a fourth dimension representing time. But mathematician Ben Tippett at the University of British Columbia, ...

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

We’re quickly learning more about time crystals, strange phases of matter that appear to break time-translation symmetry – something that was thought impossible until recently. Now scientists have ...

Now that we’ve ticked past the one-year mark of Covid-19 safety restrictions, the calendar is scrolling once more through the same holidays that punctuated the early pandemic. Yet again, curtailed ...

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 ...
