Abstract

We discuss the implications of purely classical, instead of quantum, theory of gravity for the gravitational wave spectrum generated during inflation. We show that a positive detection of primordial gravitational waves will no longer suffice to determine the scale of inflation in this case -- even a high-scale model of inflation can bypass the observational constraints due to large uncertainties in the initial classical amplitude of the tensor modes.

Additional Information:
v1: 4 pages; v2:6 pages. This is the first paper to argue that a positive detection of B-modes would signify that initial conditions for primordial gravity waves is set by quantum initial conditions and not by classical ones
