We’re all too familiar with the inexorable march of time, but why exactly it flows in one direction remains a mystery of physics. A few years ago Australian physicist Joan Vaccaro proposed a new ...

Research published recently in the journal Nature Communications considers the influence of the quantum mechanics concept of superposition on timekeeping. Superposition refers to the ability of an ...

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 ...

If dark energy continues its dominance in the Universe, every galaxy beyond our neighborhood will one day no longer be visible (via NASA) Dark energy is an unknown form of energy that is proposed to ...

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.

The special theory of relativity and quantum electrodynamics are two important fundamentals of modern physics. They have been experimentally verified many times already and both have passed all the ...

One of the most mind-bending aspects of Albert Einstein's Theory of Relativity is time dilation. Time moves more slowly for a person in motion compared to a person at rest. This effect also applies in ...

Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks. A phenomenon of ...
