from Einstein's eclipse to images of black holes
Chronicles the century of discovery and physics that attempts to refine Einstein's general theory of relativity. In 1919, astronomers made a discovery that confirmed Einstein's theory that gravity bends light, and in the generations that followed, scientists have studied gravity's effects in greater detail, which led them to determine that the universe is expanding and provided the first clues into dark energy and dark matter. Today, a globe-spanning array of radio dishes, The Event Horizon Telescope, studies the massive black hole at the center of the Milky Way to test further Einstein's revolutionary theories.
