The relation between the angular diameter distance and redshift (Formula presented) relation) in a spherically symmetric dust-shell universe is studied. This model has large inhomogeneities of matter distribution on small scales. We have discovered that the relation agrees with that of an appropriate Friedmann-Lemaître (FL) model if we set a “homogeneous” expansion law and a “homogeneous” averaged density field. This will support the averaging hypothesis that a universe looks like a FL model in spite of small-scale fluctuations of density field, if its averaged density field is homogeneous on large scales. © 1998 The American Physical Society.
