universe—and with it the problem of Time.
With the substitution of waves of probability for concrete particles, the world lines of objects are no longer the fixed and simple paths they once were. Geodesics have an infinite proliferation of possible branches, at the whim of sub-atomic indeterminism.

classical laws. But there is a fundamental difference. The apparent reality of the
universe is the same—but it rests upon a quicksand of possible change.
