Query: Is the island universe model consistent with observations?   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.
