✦ Synopsis

We discuss some physics of quantum gravity on the basis of a hybrid model of lattice gravity, particularly in the strong-coupling region. As a clue to explore the region, we make a comparison between QCD and quantum gravity. Although we do not know what are 'physical states' in highly curved space except for a few cases, we can get several hints on the physics by analogy with &CD; a physical picture of quantum spacetime is obtained, which is consistent with the so-called spacetime foam.

We revisit the quantization of matter-coupled, two-dimensional dilaton gravity. At the classical level and with a cosmological term, a series of field transformations leads to a set of free fields of indefinite signature. Without matter the system is represented by two scalar fields of opposite sign
