Abstract

"Extended" and "hyperextended" inflationary models of the universe have been developed which avoid the extreme fine-tuning required by all previous approaches. The models also generate a new source of inhomogeneities that affect large-scale structure. The most surprising feature is the role that inflation can play in altering the nature of the gravitational force.
