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.

Explore how Albert Einstein transformed our understanding of the universe with groundbreaking theories like relativity and the photoelectric effect. Discover the genius behind E = mc² and the ...

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 ...

Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into the basic laws of physics but instead emerges from gravity’s effect on heat ...

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

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

NPL has shared the results of a time dilation demonstration—which shows that time travels faster as height increases, as predicted by Albert Einstein's theory of general relativity. The demonstration ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

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 ...
