Throw a baseball and you can track its arc across the sky without disturbing it. Scientists don’t have that luxury with quantum particles. When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. This transition from the fuzzy quantum world to the sharp reality of common experience is as vital as it is controversial. How do objects shed their quantum weirdness when measured? Join a debate of current theories, including tales of infinite universes where anything and everything happens.
