Time may be an illusion derived from quantum entanglement

A new model revives the Page-Wootters mechanism, showing time emerging from entanglement between a clock and a system. It addresses the 'problem of time' between quantum mechanics and general relativity, with the nuance that clocks must approach classical limits. A recent overview article (Coppo et al.) further explores this idea and the block universe, reinforcing the philosophical implications. A dense philosophical article from the IEP discussing what science requires of time adds to the philosophy-of-time discussion.
