The Michelson Morley Light Speed Failure

The Michelson Morley Light Speed Failure

How a failed attempt to measure 'aether' accidentally paved the way for Einstein and modern physics.

Nineteenth-century scientists believed light required an invisible medium called aether to travel through space.

Michelson and Morley floated their equipment in liquid mercury to isolate it from outside vibrations.

The experiment failed to detect the expected aether wind despite using highly sensitive light interference patterns.

Physicists initially proposed that equipment physically shrinks to explain why the aether wind remained hidden.

Einstein solved the mystery by declaring the speed of light absolute and the aether entirely unnecessary.

The failed experiment paved the way for special relativity by proving space and time are flexible.
