blueprint for ether theory

The ether theory proposed that space is filled with a substance called "ether" that acts as a medium for light and electromagnetic waves, similar to how air carries sound. It was believed that this medium was necessary for the transmission of forces and waves across the universe. However, experiments like the Michelson-Morley experiment failed to detect the ether’s presence, leading to its abandonment. Modern physics, through Einstein’s theory of relativity, explains light and forces without needing an ether, viewing space as a fabric that can bend and stretch rather than a medium filled with a substance.
