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 principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...

Last week, we touched upon E=mc2, and how Einstein’s theory of relativity turned the world of physics upside-down. Now, we’re using that theory to show why the very concept of time may not be what you ...

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

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 ...

I have a question regarding time dilation that I thought of last night listening to an audiobook, Project Hail Mary. I am an amateur astrophotographer, and marvel at the distance to deep-space objects ...

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 ...
