5 The Time Arrow of Spacetime Geometry In the framework of general relativity, gravity is a consequence of spacetime curvature. Its dynamical laws (Einstein’s field equations) are again symmetric under time reversal.

6 The Time Arrow in Quantum Cosmology Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough. (Stephen Weinberg 1977)
