Eddington Tests Einstein's General Relativity

May 29th, 1919 105 years ago

Arthur Eddington and Andrew Claude de la Cherois Crommelin conducted an expedition to observe a solar eclipse in 1919, aiming to test Albert Einstein's theory of general relativity. They traveled to the island of Príncipe, off the west coast of Africa, where they successfully measured the position of stars near the sun during the eclipse. The observations confirmed Einstein's prediction that light would bend around massive objects, marking a significant milestone in modern physics.
