The purpose of this thesis is to explore quantum gravity and its phenomenological consequences for dark matter, gravitational waves and inflation. A new formalism to classify gravitational theories based on their degrees of freedom is introduced and, in light of this classification, it is argued that dark matter is no different from modified gravity. Gravitational waves are shown to be damped due to quantum degrees of freedom. The consequences for gravitational wave events are also discussed. The non-minimal coupling of the Higgs boson to gravity is studied in connection with Starobinsky inflation and its implications for the vacuum instability problem is analyzed.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061GravitationCosmologyElementary particles (Physics)Quantum field theoryClassical and Quantum GravityCosmologyElementary Particles, Quantum Field TheoryGravitation.Cosmology.Elementary particles (Physics).Quantum field theory.Classical and Quantum Gravity.Cosmology.Elementary Particles, Quantum Field Theory.530.11015153530.1Kuntz Iberêauthttp://id.loc.gov/vocabulary/relators/aut837276BOOK9910337876103321Gravitational Theories Beyond General Relativity1870741UNINA
