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 ...

Time dilation, a captivating concept embedded in Einstein’s theory of relativity, has been experimentally validated on Earth. With the use of ultra-precise clocks, scientists have been able to ...

WASHINGTON (Reuters) - Time is a slippery thing, as profound thinkers like physicist Albert Einstein and, well, fictional time traveler Dr. Who plainly understood. The latter, in a 2007 episode of the ...

The claims in the comment by Bonder et al. 1 are incorrect and are rooted in a confusion of basic aspects of classical relativity and quantum mechanics. Here we briefly address the mistakes and ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy ...

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 ...

Time dilation, brought about by the relativistic expansion of space, has resulted in the observed slowing of 'clocks' in the early universe. When you purchase through links on our site, we may earn an ...

Einstein’s equations look simple on paper but when physicists follow them to their logical end, the universe becomes far ...
