Is Planckian discreteness observable in cosmology?

A Planck scale inflationary era – in a quantum gravity theory predicting discreteness of quantum geometry at the fundamental scale – produces the scale invariant spectrum of inhomogeneities with very small tensor-to-scalar ratio of perturbations and a hot big bang leading to a natural dark matter genesis scenario. Here we evoke the possibility that some of the major puzzles in cosmology would have an explanation rooted in quantum gravity.
