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 ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

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 ...

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 ...
