100 years ago today, Albert Einstein set down the equation that rules the universe. The theory of relativity describes how matter and energy distort the geometry of the cosmos to produce the effect we call gravity. It’s a standard trope in science writing to say that some theory or experiment transformed our understanding of space and time. General relativity did just that. This photo of #AlbertEinstein explaining a theorem to reporters in Pittsburgh was first published in December 1934.
