Does time differ from change? Philosophical appraisal of the problem of time in quantum gravity and in physics

摘要: Abstract After reviewing the problem of time in Quantum Gravity, I compare from a philosophical perspective, both Carlo Rovelli's and Julian Barbour's (before Shape Dynamics) understanding Gravity dynamics general, trying to show that those two relational understandings differ. Rovelli argues there is change without can be abstracted any whereas Barbour claims some motions are better than others for constituting duration standards all universe. conclude by few remarks on Bergson׳s criticism physics light debates give surrationalist (as Bachelard understood it) answers critique spatialized Physics.
