摘要: Microphysical laws are time reversible, but macrophysics, chemistry and biology not. This chapter explores how this asymmetry (a classic example of a broken symmetry) arises due to the cosmological context, where non-local Direction Time is imposed by expansion universe. situation best represented an Evolving Block Universe, local arrows (thermodynamic, electrodynamic, gravitational, wave, quantum, biological) emerge in concordance with because global Past Condition results Second Law Thermodynamics pointing future. At quantum level, indefinite future changes definite past wave function collapse events.
