Following the standard scenario of galaxy formation, density fluctuations with amplitude δ∼10−3 should have been present at the recombination time tR in order that galaxies and clusters of galaxies can be formed. Recent observations of the anisotropy of the cosmic background radiation(CBR), however, indicate that δ is less than 10−4 at tR for adiabatic perturbations in the baryon-dominated universe.
