We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.
A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of ...
Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...
A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...
The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...
Humans have been studying total solar eclipses for millennia to better understand the cosmos. Total eclipses have helped prove Einstein's theory of relativity and led to the discovery of helium. Here ...
A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...
