cosmology is the new alchemy

Vernon_01

Why is cosmology so popular? Books by writers such as Paul Davies and Stephen Hawking on fine-tuning or the multiverse routinely become bestsellers. They’re good writers, of course. And there’s the aesthetic appeal of cosmology too, offering a ceaseless stream of heavenly images at which to wonder and gaze. But I suspect there’s more to it than that. After all, many other branches of physics are progressing as fast, and arguably have a bigger impact upon our daily lives. But when did you last pick up a paperback on solid state physics, one of the largest contemporary research fields? Or who would choose a book about optics over one about the Big Bang? Chaos theory gets a look in, as does quantum theory — though that’s very close to cosmology, as the history of universe turns on the physics of the very small. So here’s a possibility. Cosmology is so popular, not just because of the science, but because it allows us to ask the big questions — where we come from, who we are, where we’re going. It’s metaphysics by other means. If the Scholastic theologians of the Middle Ages liked to speculate about the number of angels on the heads of pins, we today like to speculate about the number of dimensions wrapped up in string theory. The activities are similar insofar as they feed the delight we find in awe-inspiring wonder.
