The argument that the relativistic space-time named (after H. Weyl) "block universe" eliminates the possibility of changes, free will, becoming (etc.) has been used to conclude that between relativity (which demands separability and determinism) and quamtum mechanics (which demands nonseparability and indeterminism) there is no "peaceful coexistence", from a philosophical point of view. But the issue is not so simple as N. Maxwell (Are Probabilism and Special Relativity Incompatible?, Philosophy of Science, 52, 23-43. 1985) and H. Stein (On Relativity Theory and Openness of the Future, Philosophy of Science, 58, 147-167, 1991) have pointed out. [But I did not remember what they wrote, since I've read these papers 30 years ago]. s.
