The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

When they look for violations of Einstein’s general relativity, physicists deliberately plan experiments to find nothing at all. In 1887, physicists Albert Michelson and Edward Morley performed one of ...

“The one sentence statement of general relativity is that ‘gravity is the curvature of spacetime,’” explains Dr. Sean Carroll, assistant professor of physics at the University of Chicago. “Really, the ...
