Abstract
In this paper, we consider the spatial gauge symmetries spontaneously break down in GR, and graviton becomes massive on this spatial condensate background. Such model can be considered as a simplest example of massive gravity. We then apply our massive gravity theory to inflation, the graviton mass removes the IR divergence of the inflationary loop diagram.

5 pages, 1 figure; at V2, we slightly change the title, re-organize the introduction sector, add the remarks on the self-consistency, and correct some typos; V3, more details are included, V4, more references and discussions added
