Query: Quantized Cosmology   This paper discusses the problem of inflation in the context of
Friedmann-Robertson-Walker Cosmology. We show how, after a simple change of
variables, one can quantize the problem in a way which parallels the classical
discussion. The result is that two of the Einstein equations arise as exact
equations of motion and one of the usual Einstein equations (suitably
quantized) survives as a constraint equation to be imposed on the space of
physical states. However, the Friedmann equation, which is also a constraint
equation and which is the basis of the Wheeler-DeWitt equation, acquires a
welcome quantum correction that becomes significant for small scale factors. We
discuss the extension of this result to a full quantum mechanical derivation of
the anisotropy ($\delta \rho /\rho$) in the cosmic microwave background
radiation, and the possibility that the extra term in the Friedmann equation
could have observable consequences. Finally, we suggest interesting ways in
which these techniques can be generalized to cast light on the question of
chaotic or eternal inflation. In particular, we suggest one can put an
experimental lower bound on the distance to a universe with a scale factor very
different from our own, by looking at its effects on our CMB radiation.
