ABSTRACT
The previous chapter developed and defended, on metaphysical grounds, a causal theory of dynamic time. But time is a subject that is inextricably intertwined with theories of physics. Physical theories place a constraint on a theory of time, requiring it to exhibit consistency with empirical observations and acceptable interpretations of those theories. In particular, the three towering theories of twentieth-century physics-the Special Theory of Relativity (STR), the General Theory of Relativity (GTR), and Quantum Mechanics (QM}-are generally regarded as calling into question the conceptual framework of a causal theory of dynamic time.
