To be foundational, theory must have established and maintained a direct dependence upon empirical evidence with the goal of learning that which empirical evidence is revealing to us. Three pervasive problems with theoretical physics are identified: 1. The failure to define mass; 2.Lack of attention to detail; 3. Accepting indirect empirical evidence as sufficient support for orthodoxy; 4. Lack of a foundational system of units; 5. Turning learning backwards.
