Solution of the size and horizon problems from classical string geometry
Heliudson Bernardo, Robert Brandenberger, Guilherme Franzmann
Abstract
A bstract In a recent paper we developed a string cosmology background from classical string geometry. Here, we show that this background yields a solution to the size and horizon problems of Standard Big Bang cosmology while remaining compatible with the Transplanckian Censorship Conjecture. We also take a first look at the evolution of cosmological perturbations in this model.
