O problema da seta do tempo na cosmologia holográfica em laços.

Abstract

The time arrow problem is a well known question in cosmology and it is about knowing why the universe started from a low entropy state, evolving in a way that its entropy never decreases. Loop quantum cosmology seeks to describe the behavior of the universe in the period close to the Big Bang singularity. By relating loop quantum cosmology to the modified Bekenstein-Hawking equation, we have what we call holographic loop quantum cosmology. In view of this perspective, we obtain a possible solution to the problem of violation of the generalized second law of thermodynamics in the context of loop quantum cosmology in the early periods of the universe.
