What if quantum mechanics is not fundamental? What if time itself is an illusion? In this new episode, physicist Julian Barbour returns to share his most radical ideas yet. He proposes that the universe is built purely from ratios, that time is not fundamental, and that quantum mechanics might be replaced entirely without the need for wave functions or Planck’s constant. This may be the simplest vision of reality ever proposed. As a listener of TOE you can get a special 20% off discount to The Economist and all it has to offer!
