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 ...

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.

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.

In 1980, a Russian cosmonaut named Sergei Krikalev unknowingly became one of history's most famous time travelers. After ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

Despite more than a century of efforts to show otherwise, it seems Albert Einstein can still do no wrong. Or at least that’s the case for his special theory of relativity, which predicts that time ...
