It gave us black holes and the theories behind Interstellar, but its impact can't be measured at the box office. Learn what it still means to researchers live at 8 p.m. You can save this article by ...

If you drop a bowling ball and a baseball, you can generally expect them to fall and hit the ground at the same time. Even in conditions with extreme gravity, very different from the scale of physics ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...

A newly surfaced letter attributed to Albert Einstein offers a rare, intimate look at the man behind the equations, including ...

One hundred years after Albert Einstein proposed his theory of general relativity, a theoretical physicist, Erik Verlinde from the University of Amsterdam, proposes a revision, suggesting that gravity ...
