MichelsonMorleykísérlet
The Michelson–Morley experiment, conducted in 1887 by Albert A. Michelson and Edward W. Morley, was a foundational test of the then-accepted idea of a luminiferous aether and of the isotropy of the speed of light. The central question was whether Earth’s motion through the hypothetical aether would produce a detectable difference in the speed of light along different directions.
The experiment used a Michelson interferometer, an optical instrument that splits a beam of light into two
Michelson and Morley rotated the device and searched for any systematic fringe shifts that would indicate
The null result challenged the prevailing aether concept and prompted further theoretical and experimental work. It
