    On this day in history, May 29, 1919...

    English astronomer, physicist, and mathematician Sir Arthur Eddington traveled to the island of Príncipe off the west coast of Africa to watch the solar eclipse of May 29, 1919. During the eclipse, he took pictures of the stars in the region of space very near the Sun. According to the theory of general relativity, stars with light rays that passed near the Sun would appear to have been slightly shifted because their light had been curved by its gravitational field. This effect is noticeable only during eclipses, since otherwise the Sun's brightness obscures the affected stars. Eddington's observations were published the next year, which confirmed Einstein's theory, and were hailed at the time as a conclusive proof of general relativity over the Newtonian model
