One of Albert Einstein's greatest insights was realizing that time is relative. It speeds up or slows down depending on how fast one thing is moving relative to something else. How much does it change ...

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 flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

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 ...

Measuring the time discrepancy between Earth and Mars will help make future navigation and communication systems on the Red ...

Dark energy is an unknown form of energy that is proposed to drive the accelerated expansion of the universe. A new study by University of Georgia professor Edward Kipreos suggests that changes in how ...

Black holes are strange and fascinating celestial phenomena that challenge the laws of physics. From swallowing up entire stars to warping the very fabric of space-time and generating massive gravity ...

You're driving on a rainy highway when suddenly another car swerves into your lane. In that critical moment, something strange happens — time itself seems to stretch. The oncoming headlights approach ...
