“When left alone, quantum particles behave as multiple images of themselves (as waves, really), simultaneously moving through all possible paths in space and time. Now, again, why do we not experience this multitude around ourselves? Is it because we are probing things around us all the time? Why do all experiments that involve, say, the position of a particle make the particle suddenly be somewhere rather than everywhere? No one knows. Before you probe it, a particle is a wave of possibilities. After you’ve probed it, it is somewhere, and subsequently it is somewhere for ever, rather than everywhere again. Strange, that. Nothing, within the laws of quantum physics, allows for such a collapse to happen. It is an experimental mystery and a theoretical one. Quantum physics stipulates that whenever something is there, it can transform into something else, of course, but it cannot disappear. And since quantum physics allows for multiple possibilities simultaneously, these possibilities should then keep existing, even after a measurement is made. But they don’t. Every possibility but one vanishes. We do not see any of the others around us. We live in a classical world, where everything is based on quantum laws but nothing resembles the quantum world.”

“The melancholy of the antique world seems to me more profound than that of the moderns, all of whom more or less imply that beyond the dark void lies immortality. But for the ancients that ‘black hole’ is infinity itself; their dreams loom and vanish against a background of immutable ebony. No crying out, no convulsions—nothing but the fixity of the pensive gaze.With the gods gone, and Christ not yet come, there was a unique moment, from Cicero to Marcus Aurelius, when man stood alone. Nowhere else do I find that particular grandeur.”
