Is the island universe model consistent with observations?

Astrophysics 2009-11-11 v2 General Relativity and Quantum Cosmology High Energy Physics - Theory

Abstract

We study the island universe model, in which initially the universe is in a cosmological constant sea, then the local quantum fluctuations violating the null energy condition create the islands of matter, some of which might corresponds to our observable universe. We examine the possibility that the island universe model is regarded as an alternative scenario of the origin of observable universe.
