Abstract

We investigate the dynamics of a spherical void in the FLRW universe and discuss its observational consequences in redshift space. We show that a void is prolonged in the line of sight and that the deformation ratio depends on the dynamics of the background universe. Our results together with a future deep sky survey of galaxy distribution will confirm the existence of a cosmological constant.
