Case of the Ether

The "Ether" case refers to historical experiments in the 19th century that aimed to detect a medium called the "luminiferous ether," thought to fill space and carry light waves. Despite numerous efforts, scientists found no evidence of such an ether. This led to the development of Einstein's theory of special relativity, which explained that light doesn't need a medium to travel and intrinsic properties of space-time. The case highlights how scientific ideas evolve with better evidence, and it emphasizes the move from assuming unseen mediums to understanding the universe through more accurate models.
