DESCRIPTION:In this talk\, I will show how a gauge-theoretic a
 pproach to Jackiw–Teitelboim (JT) gravity naturall
 y yields a two-dimensional Henneaux–Teitelboim (HT
 ) unimodular theory\, applicable to both flat and 
 curved spacetimes. Under a mini-superspace reducti
 on\, the Wheeler–DeWitt equation becomes a Schrödi
 nger-like equation admitting a consistent\, unitar
 y quantum description. The resulting wavefunction 
 describes a quantum distribution for the scale fac
 tor\, illuminating cosmic expansion and contractio
 n\, and allowing topology change at a=0.
