Physicists in Germany have performed the most precise Michelson-Morley experiment to date, confirming that the speed of light is the same in all directions. The experiment, which involves rotating two ...

The MICHELSON-MORLEY EXPERIMENT was performed in the basement of a WESTERN RESERVE UNIV. dormitory in July 1887 by ALBERT A. MICHELSON of the Case School of Applied Science and EDWARD W. MORLEY of ...

Last week over in Twitter-land, Philip Ball asked an interesting question: I’ve written a fair bit about historical science, and read more than I’ve written, so this question stuck with me, and seems ...

Two changes improved the apparatus over the one used at Potsdam [in 1886]. Morley suggested floating the heavy sand stone slab bearing the optical parts on mer cury. The stone, about 5 feet square, ...

Simultaneous tests of Einstein’s special theory of relativity performed in Europe and Australia have allowed physicists to conclude that the speed of light is constant in all directions, without ...

Physicist Albert A. Michelson received the 1907 Nobel Prize in Physics for developing an interferometer, which incorporates a translucent mirror to divide a beam of light waves, route them through ...

Physicists regard this work as a crucial step in our journey toward an understanding of the very nature of space and time itself Had the results of this measurement been different, Einstein's theory ...
