Since there may exist dark matter particles nu and delta with mass similar to 10(-1) eV in the universe, the superstructures with a scale of 10(19) solar masses (large number A similar to 10(19)) appeared during the era near and before the hydrogen recombination. Since there are superstructures in the universe, there may be no necessity for the existence of dark energy. For checking the superstructure in the universe by CMB anisotropy, we need to measure CMB angular power spectrum - especially around ten degrees across the sky - in more details. While neutrino nu is related to electroweak unification, the fourth stable elementary particle delta may be related to strong-gravity unification, which suggests p + (p) over bar -> n + (delta) over bar and that some new baryons appeared in the TeV region.
