Albert Einstein’s general theory of relativity predicts that a rotating mass like the Earth pulls the fabric of space and ...

A best-yet measurement of one of general relativity’s most mind-boggling effects is “another feather in Einstein’s cap” ...

“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 ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...
