n-scales introduce a generalization of time-scales that has been put forward
to unify continuous and discrete analyses in higher dimensions. In this paper we
investigate massive scalar field theory on a regular n-Scale. We have given the
modified field equation that is appropriate to this space-time structure and gave the
mode solutions. If the space-time is discrete and unbounded, we have found that
no massive scalar field can exist. Hence, we concluded that unbounded discrete
space-time cannot exist. If discrete space-time exists, it has to be bounded in each
dimension.
