Which astronomer led the 1919 solar eclipse expedition that confirmed Einstein's theory of general relativity?
Tap your pick
Arthur Eddington traveled to the island of Principe off the coast of West Africa to photograph stars near the Sun during a total solar eclipse. By measuring how much the Sun's gravity bent the incoming starlight, he provided the first empirical proof of Einstein's revolutionary theory. This historic measurement instantly propelled Einstein to global fame. Photo: George Grantham Bain Collection, Library of Congress Prints and Photographs Divi, Wikimedia Commons, Public domain.
