An acclaimed physicist signposts a new revolution in fundamental physics, and with it a new description of reality For the last century, physics has been following the paths set out by the same two theories—quantum mechanics and general relativity—and, let’s face it, it’s getting pretty boring. Despite these great theories being fundamentally in conflict, most scientists are simply chasing decimal points in laboratories. To give the deeper explanation of reality we seek, we need new ways to explore and critique our best ideas of the universe on the smallest and largest scales. The situation is much like that in 1890, right before Planck, Einstein and Bohr blew the roof off Newtonian physics.
