The Trouble with Physics and Realism

The mind calls out for a third theory to unify all of physics, and for a simple reason, Nature is in an obvious sense “unified. .  .  But in both quantum theory and general relativity, we encounter predictions of physically sensible quantities becoming infinite. This is likely the way that nature punishes impudent theorists who dare to break her unity.                                                                          Lee Smolin, The Trouble with Physics              In The Trouble with Physics, Lee Smolin presents a powerful critique of the state of modern physics.   http://www.thetroublewithphysics.com/  The cause of the “trouble with physics” is that the two leading theories of physics— quantum theory and the general theory of relativity (i.e., gravity) — are mutually incompatible.  The standard explanation for this incompatibility is that quantum physics, with its wave-particle duality and uncertainty principle, governs the world of the very small, while gravity, which by definition is proportional to mass, governs the...
