In this study, the masses of various particles in physics and the processes of cosmic changes were precisely calculated. Given six variables (three generation neutrino masses, photon mass, gluon mass, and electromagnetic force), everything is calculated. The core is to understand the characteristics of quantum space. Particles have no proper mass. Logarithmically compressed three generation quantum space imparts mass to the particle. The calculated values are such as follows: electron neutrino 0.1533 eV, weak force 1.011E-6, gravitational force 5.906E-39, up quark 2.250 MeV, charm quark 1275.1 MeV, down quark 4.766 MeV, strange quark 95.28 MeV, H boson 125.02 GeV, cosmological constant 1.1056E-52 /m2, dark energy : dark matter : ordinary matter = 69.5% : 25.8% : 4.7%. From the cosmological constant, the radius of Planck star is calculated as 10.05 billion years. The 73% (=10.05/137.7) is called the proportion of dark energy, and the 27% (=37.2/137.7) is called the proportion of matter. Therefore, it proves that the definition of dark energy is wrong. The standard for calculating our universe is not 5.391E-44 seconds, but 10.05 billion years. That is, right after the Big Bang, the universe began at about the size of our solar system.
