Making it up as we go
More from BooksFor the scales at which we live — the buildings we inhabit, the vehicles we drive, the sports we play — classical physics is a useful, highly accurate and reassuringly comprehensible system. But at scales we never personally encounter, at immense velocities, infinitesimal sizes or cosmic distances, things are not so simple. In these worlds, time passes more slowly or quickly depending on one’s own speed, light beams travel on bendy paths through a universe of dented spacetime and electrons are not distinct particles but rather probabilistic clouds which collapse into specific measurements only when we observe them. The novelist and playwright Michael Frayn is fascinated by such worlds.
