The quantum fluctuation cannot have contained 'time dips' i.e. gravity wells within which time could operate to produce gravity. Inflation is supposed to have occurred from size 10^-40 cm to well less than 1 cm. Could it be that gravity was negligible, in effect because the 'dips in space' were too small to get a significant time differential for 'Time Inertia' to work. At macro dimensions, from say a significant fraction of 1cm there is enough radius to the universe for tiny dips to have slopes where time ran slow allowing a beginning to gravity. In essence The cause /effect is Shape causes 'Time Inertia' causes gravity.
