Physics and Philosophy - Thoughts on the Implications of Quantum Mechanics, and Other Matters #7

7. Although physics and philosophy travel different paths through the world of truth, an occasional intersection may be found. When physics reaches the furthest extant of its reach, which can often be a grey, uncertain area, then philosophy holds sway. Often the philosophical species encountered will manifest as metaphysics. Conceived forces, causes and effects can be useful tools for the scientist pushing the boundary of human knowledge. Possibilities may provide avenues worth exploring. Metaphysical musing lacking a basis in physical reality are little more than mysticism at best, or intellectual self-stimulation at least. Modern truth requires proof.
