Abstract: Recently some progress has been made on the study of dark matter and dark energy in the universe by British scientists on the basis of analysis of the observational datums by Paranal Observatory.If the dark matter in the universe is regarded as being made up of Fermi type neutrino ｖ０ｅＦ and its supersymmetry companion,neutralino Ｕ－０ｅＢ,the characteristics are calculated according to the mass formula and the radius formula given by the damping scale of free currents of two classes of celestial body evolution and the results basically tally with observations,which supports  the theory of hot dark matter.The correlation between the dark matter and the dark energy is also discussed.

Key words: dark matter, dark energy, neutrino, neutralino, free current damping scale, supersymmetry
