Nothing is fixed in time or space. Everything – from quantum particles to people, planets and galaxies – is in constant motion, and part of a constellation of inextricably interwoven systems. That might seem like a strictly academic observation with little bearing on your day-to-day life, but, as Thomas Nail, a professor of philosophy at the University of Denver, argues in this short video, overlooking this fact can have real-world consequences. Instead of understanding the Universe in terms of inflexible objects, Nail proposes that we view our world in terms of processes subject to constant change. This, he argues, will lead to improvements in science, public policy and even interpersonal relationships.
