On the Scientific Theories of Special and General Relativity At the beginning of the twentieth century, Albert Einstein revolutionized the way scientists think about space and time. In his special theory of relativity, Einstein showed that time and length are not as absolute as everyday experience would suggest: Moving clocks run slower, and moving objects are shorter. Those are just two of the unusual properties of Einstein’s world! Another consequence of special relativity is the most famous formula of all: E=mc², stating that two physical quantities which physicists had defined separately, namely energy and mass, are in fact equivalent. In Einstein’s general theory of relativity, space and time become even more flexible. “Your mileage may vary,” and so may the time intervals you measure, depending o Read more
