Time is not the problem

摘要: Attempts to quantize general relativity encounter an odd problem. The Hamiltonian that normally generates time evolution vanishes in the case of as a result diffeomorphism invariance. theory seems be saying does not exist. most obvious feature our world, namely progress and world changes accordingly becomes problem this presumably fundamental theory. This is called time. In essay we argue unphysical idealization. We are caught "problem time" trap because took wrong turn early days by permanently including split geometry matter into physical theories. show another possibility exists circumvents also sheds new light on other problems like cosmological constant horizon universe cosmology.
