100 years ago today, a solar eclipse helped confirm Einstein's theories on gravity
On May 29, 1919, British astronomers Frank Dyson and Arthur Eddington positioned themselves in the path of a total solar eclipse, on opposite sides of the Atlantic, for an experiment putting Einstein's theories on gravity to the test. Their results would prove to be one of the most important physics experiments of the 20th century.
