Query: Entropic Force Scenarios and Eternal Inflation   We examine various entropic inflation scenarios, under the light of
eternality. After describing the inflation realization and the normal condition
for inflation to last at the background level, we investigate the conditions
for eternal inflation with the effect of thermal fluctuations produced from
standard radiation and from the holographic screen. Furthermore, we incorporate
stochastic quantum fluctuations through a phenomenological, Langevin analysis,
studying whether they can affect the inflation eternality. In
single-holographic-screen scenarios eternality can be easily obtained, while in
double-screen considerations inflation is eternal only in the high-energy
regime. Thus, from the cosmological point of view, one should take these into
account before he can consider entropic gravity as a candidate for the
description of nature. However, form the string theory point of view, inflation
eternality may form the background for the "Landscape" of string/M theory
vacua, leading to new perspectives in entropy gravity.
