There are some experiments throughout the history of physics that challenge the old system of thinking, while opening up doors for new ideas and progressions to be made. One such experiment is the Michelson and Morley experiment of the earth's velocity through "aether". Albert Michelson and William Morley were two American physicists who worked in Cleveland, Ohio. They grew up in a time where scientists believed that the universe 'floated' in a special substance called …showed first 75 words of 1030 total…

It led scientists to rethink the laws of physics, and led to a revolution on the concept of relativity. Bibliography: "Michelson-Morley Experiment" article by R.S.
