Inflation Scheme Derived from Universal Wave Function Interpretation of String Theory

Abstract

Zhi Gang Sha and Rulin Xiu

Inflation is the most commonly accepted theory in cosmology to explain why the universe appears flat, homogeneous, and isotropic, as well as the origin of the large-scale structure of the cosmos and why no magnetic monopoles have been detected. However, so far, the origin of the inflation epoch and what is the hypothetical field, the inflaton, giving rise to inflation, remains unknown. String theory is one of the promising candidates for the grand unification theory. Grand unification theory is to use one mathematic formula to describe everything. In this work, we study the inflation scheme in a new development in string theory, universal function interpretation of string theory (UWFIST). We show that from UWFIST we can derive from the fundamental theory that the long-range vibration is the possible candidate of inflaton. We estimate the vacuum energy created by the long-range vibration and show that it can indeed drives the inflation.
