Gravitational Fluctuations as an Alternative to Inflation II. CMB Angular Power Spectrum

open access: yesUniverse, 2019
Power spectra always play an important role in the theory of inflation. In particular, the ability to reproduce the galaxy matter power spectrum P ( k ) and the CMB temperature angular power spectrum C l ’s to high accuracy is often ...

Starobinsky potential and power suppression in hybrid loop quantum cosmology

open access: yesPhysics Letters B
We study the effect on the primordial tensor power spectrum of varying the number of e-folds during slow-roll inflation in Loop Quantum Cosmology with a Starobinsky potential. Using the hybrid quantization approach, we derive the effective mass governing

Consciousness in the Universe

open access: yesPensamiento. Revista de Investigación e Información Filosófica, 2013
So far we can identify at least three concepts within modern cosmology that bring into debate the question of consciousness in the universe: 1) Fine Tuning; 2) The Anthropic Principle and 3) The Multiverse.

Quantum Cosmology

open access: yes, 2006
Quantum cosmology in general denotes the application of quantum physics to the whole universe and thus gives rise to many realizations and examples, covering problems at different mathematical and conceptual levels. It is related to quantum gravity and more specifically describes the application to cosmological situations rather than the construction ...

QUANTUM COSMOLOGIES AND THE “BEGINNING”

open access: yesZygon, 1991
. The cosmology proposed by Stephen Hawking has been understood as support for an atheistic stance, due mainly to its view of the nature of time in combination with the absence of explicit boundary conditions.

A novel link between Wheeler-DeWitt quantization and (effective) loop quantum cosmology

open access: yesPhysics Letters B
It is shown that several prescriptions for the effective continuum limit of the flat Friedmann-Lemaitre-Robertson-Walker loop quantum cosmology can be understood as the exact classical limit of the Wheeler-DeWitt quantization of certain dynamical systems,
