| 英文摘要 | In this paper we fully calculate the non-gaussianity of primordial curvature perturbation of the island universe by using the second order perturbation equation. we find that for the spectral index n(s)similar or equal to 0.96, which is favored by current observations, the non-gaussianity level f(nl) seen in an island will generally lie between 30 and 60, which may be tested by the coming observations. in the landscape, the island universe is one of anthropically acceptable cosmological histories. thus the results obtained in some sense mean the coming observations, especially the measurement of non-gaussianity, will be significant to clarify how our position in the landscape is populated. |
