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.

Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into ...

Explore how Albert Einstein transformed our understanding of the universe with groundbreaking theories like relativity and ...

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 ...

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 ...

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 ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...
