“Anybody who has done high school physics knows Newton’s Third Law. For every action there is an equal and opposite reaction. You push against a wall; it pushes back against you. I love the poetry hidden in these truths, in the many laws we’ve discovered that underpin the universal fabric. We search for meaning ever hungrier, perhaps even with desperation: the symmetry in the equations freaks us out; for all we know, there is just us on this lonely little marble in the inky void.”
