There is a category of stable non-baryonic dark matter particles in the universe at the present time: fermions or bosons with mass ~10^(-1) eV. The existence of these do not contradict the dip phenomena of the ultra-high energy primary cosmic ray spectrum at ~10^(15) eV ("knee") and ~10^(18) eV ("ankle"), nor the existence of galaxies at large red shift z~10. The mass scales sequence connected by a large number A, especially the superstructure scale, is helpful in the understanding of the Hubble constant and the cosmological constant. The extension part of this paper is related to some supposed particles: A-particle, delta-particle, and u-particle, which are helpful to explore the state of matter with super-high density, singularity, inflation in the early universe and specific to involve the beyond SM, new energy source etc. To accurately measure the rate of change for the speed of light at the present time year by year is a very important step, that can check whether the dark energy and the cosmological constant are existent or not.
