Aether: The Medium That Wasn’t
For centuries, waves meant mediums: water, air, strings. When light behaved like a wave, theorists posited a luminiferous aether—weightless, transparent, everywhere, holding galaxies the way water holds ripples. It was too neat to ignore and too slippery to measure. This essay follows the aether from respectable necessity to discarded scaffolding, and asks what modern builders—of theories, products, and teams—can learn from a medium that wasn’t. 🌌
