Because the moon has less gravity than Earth does, time passes slightly differently there. This effect was first predicted by ...

Physicists from JILA — a CU Boulder and National Institute of Standards and Technology institute — were able to measure an effect called time dilation at the smallest scale ever, which they say could ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

One of the most mind-bending aspects of Albert Einstein's Theory of Relativity is time dilation. Time moves more slowly for a person in motion compared to a person at rest. This effect also applies in ...

I am so intimidated right now...I think I understand less about relativity now than before I asked the question. I think - if I understand things as written - that time can be observed to slow for an ...

Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks. A phenomenon of ...

Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...
