Time is a fickle thing. Depending on your frame of reference, it can appear to pass slower or quicker, thanks to a wonky phenomenon known as time dilation that was described in Albert Einstein's ...

For centuries, humans have thought of time as a linear concept - but time dilation challenges that perception. Just as gravity pulls things down, time simply moves forward at a constant, unwavering ...

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 ...

Time moves differently in space. Near black holes, gravity slows clocks and stretches seconds. This explainer reveals how time bends and affects astronauts and Earth.

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.

A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of relativity. When you purchase through links on our site, we may earn an ...

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 ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to curiouskidsus@theconversation.com. Why does time change when traveling close to the ...

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 ...
