# Benefits of Objective Collapse Models for Cosmology and Quantum Gravity

@article{Okon2013BenefitsOO, title={Benefits of Objective Collapse Models for Cosmology and Quantum Gravity}, author={Elias Okon and Daniel Sudarsky}, journal={Foundations of Physics}, year={2013}, volume={44}, pages={114-143} }

We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective reduction models to three important issues: the origin of the seeds of cosmic structure, the problem of time in quantum gravity and the information loss paradox; we show how reduction models contain the necessary tools to provide solutions for these issues. We wrap up with an adventurous proposal…
