100 Years of General Relativity: Why Einstein Still Stands - by Devin Powell/ Science/ Popular Science/ popsci.com
"One hundred years ago this month, Albert Einstein redefined what gravity is, overthrowing his own hero Isaac Newton.
Newton had imagined gravity to be a force like any other that pulls on things to get them going. But Einstein wove gravity into very fabric of space and time, molding an invisible landscape of hills and valleys through which objects move. The equations describing this vision, known as the general theory of relativity, have since become a cornerstone of modern physics—opening new doors for understanding everything from how planets and stars move to existence of dark matter and the early days of the universe itself.
“Today it really is the standard model for gravity,” says Clifford Will, a physicist at the University of Florida who has devoted his career to the theory. “It has passed every experimental test with flying colors.”..."

In this 1919 negative of a solar eclipse, British scientist Sir Arthur Eddington helped verify Einstein's theory of general relativity, showing light bending around the Sun as predicted in the theory.
