Query: Quantum Gravity Scenario of Inflation based on the CMB Anisotropies   Inflationary scenario based on a renormalizable model of conformal gravity is
proposed and primordial spectrum is derived. The sharp fall off of the angular
power spectra at low multipoles in the COBE and WMAP observations are explained
by a dynamical scale of quantum gravity. At this scale, the universe would make
a sharp transition from the quantum spacetime with conformal invariance to the
classical spacetime.
