Abstract
Inflationary cosmology’s account for the emergence of the seeds of structure in the universe out of primordial quantum fluctuations is empirically successful as far as the so called scalar modes is concerned, but the situation is no so clear regarding the tensor modes. On the other hand, the usual account has some serious conceptual problems, connected to the quantum macro-objectification question ( usually known as the measurement problem in quantum theory). In the search for an approach to resolve the latter, we find substantially modified predictions (with respect to the standard ones) for one of the observables, specifically the estimates for the amplitude and shape of the spectrum of primordial gravity waves. This is an interesting example, where considerations that might have been initially thought to be “just of philosophical interest” actually led to novel and (so far better) predictions for empirical facts.
