The Earth's continents drift across the planet's surface like massive ships on an invisible ocean. Today, this fact appears in every elementary school textbook. Yet in 1912, when Alfred Wegener proposed this idea, geologists dismissed him as a crackpot. His theory remained scientific heresy for half a century before becoming geology's cornerstone. This transformation reveals something unsettling: the boundary between legitimate science and fringe nonsense isn't a fixed wall but a permeable membrane, constantly shifting as knowledge evolves. What we mock today might revolutionize tomorrow-or remain forever exiled to pseudoscience's graveyard. Understanding how these boundaries form and shift offers a compass for navigating our information-saturated world, where distinguishing breakthrough from bunk has never been more crucial or more difficult.
