Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

From what we know about No Man’s Sky, aging won’t be a source of in-game anxiety. Although characters can definitely die and the universe is big enough to explore into one’s dotage, the archbishop won ...

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 ...

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 ...

Time really does move faster on Mars, but the breakthrough that confirms it did not come from a spacecraft’s stopwatch.

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 ...
