Abstract

It has been recently proposed that the interior of a black hole is vacuum energy, and this offers a possible explanation for the dark energy of the current observable universe. In this article we explore the idea that black holes are a source of vacuum energy in the early universe as well, and could possibly explain early inflation. Our scenario pre-supposes a single aboriginal black hole as the source of vacuum energy that drives inflation and eventually evaporates due to Hawking radiation. In such a model we can estimate t_i and t_f which are the times when inflation began and ended respectively. Our simplified model leads to t_i ≈ 10^-45 sec, t_f ≈ 10^-43 sec and the number of e-foldings during inflation to be about 70.
