voids in universe-an assumption to move in past and present

voids in universe may show that there can be many universes with shape of cone.and if we assume that movement in past and future is posible ,then there is a possibility that same person exists in all universes with diferent matter of particles.this may be an assumption that when we talk about existance of past and future at the same time as present ,then we may be taking about three cones i.e. three universes forming a sphere in which we may exist in past ,present and future.
