There is a list of unsolved problems in physics on Internet Wikipedia. In this paper, sixty unsolved problems were calculated or explained through simple mathematics. The main results are as follows. (1) Generations of matter: Fourth generation particle does not exist. (2) Extra dimensions: The space of the universe has six dimensions. (3) Neutrino mass: The mass of electron neutrino is calculated to be 0.15 eV. (4) Neutrino oscillation: The 0.15 eV oscillates to 187.5 keV and 13.61 MeV. (6) Arrow of time: Our universe is 3D, and the quantization proceeds from 4D to 2D direction. (11) Dark matter: Something grows our universe by quantizing 4D space into 3D. (16) Origin of mass of most elementary particles: Extremely compressed three generation quantum spaces give mass to three generation particles. (24) Hierarchy problem: Elliptic equation must have a largest value and a smallest value. (28) Cosmological constant problem: The 10^120 is the ratio of 0D and 3D neutrino masses. (33) Supersymmetry: Elliptic equation is up & down symmetry and left & right symmetry. (38) Quantum gravity: Gravity is the Planck force of strong, electromagnetic, and weak forces. (40) Dark energy: There is a dark force greater than strong force. (41) Quantum chromodynamics: The mass of strong force is 42.15 keV, which is the root of tau mass 1776.86 MeV. (44) Hubble tension: CMB's 67.66 km/s/Mpc and Redshift's 73 km/s/Mpc are both right answers. (59) Fine-tuned universe: All universes change according to logarithmic elliptic equation, and all forces follow logarithmic parabolic equation. (60) Theory of everything: Since quantum space has a logarithmic characteristic, quantum particle must be calculated as logarithmic value.
