Morley-Michelson Experiment

The Morley-Michelson Experiment was an important scientific test conducted in the late 1800s, designed to detect the Earth's motion through the "aether," a hypothetical substance thought to carry light waves. Using a highly precise interferometer, the experiment measured differences in light speed in different directions. Surprisingly, it found no such variations, suggesting that the speed of light is constant regardless of Earth's movement. This result challenged earlier ideas and laid the groundwork for Albert Einstein’s theory of special relativity, fundamentally changing our understanding of space, time, and light.
