The current understanding of the quantum origin of cosmic structure is discussed critically. We point out that in the existing treatments a transition from a symmetric quantum state to an (essentially classical) non-symmetric state is implicitly assumed, but not specified or analyzed in any detail. In facing the issue we are led to conclude that new physics is required to explain the apparent predictive power of the usual schemes. Furthermore we show that the novel way of looking at the relevant issues opens new windows from where relevant information might be extracted regarding cosmological issues and perhaps even clues about aspects of quantum gravity.

On the Quantum-to-Classical Transition of Primordial Perturbations
A dissertation that introduces slow-roll inflation and perturbations, critiques squeezing and decoherence formalisms, and investigates the pilot-wave approach to the quantum-to-classical transition with numerical illu...

Addressing the so called quantum/classical "divide" in gravitational contexts, and its implications in cosmology
Cosmic structure would come from spontaneous collapse of quantum states, not from quantum fluctuations, which would also suppress primordial gravitational waves and avoid eternal inflation.
