We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

A spacecraft traveling at 99 percent the speed of light toward Alpha Centauri would cross 4.3 light-years in what feels like ...

Among the oft-repeated predictions of Albert Einstein's famous theory of relativity is that if a twin travels through the cosmos on a high-speed rocket, when he returns to Earth he will be noticeably ...

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its annual ...

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a black hole.
