The Formation and Evolution of the Sun and the Source of Star Energy as Well as the Sunspots and Flares of the Sun

Nebula theory is the most widely accepted hypothesis about the formation and evolution of the Solar System. This theory holds that the Sun is formed from a collapsed gas cloud 4.57 billion years ago; when the core temperature of the gas cloud rises to 10 million K, the thermonuclear reaction of hydrogen fusion into helium is ignited, then the Sun become a star; once the hydrogen in the core is exhausted, the life of the star will end. But the limited hydrogen element obviously cannot satisfy such a long-term thermonuclear reaction, in order to sustain long-term thermonuclear reactions, a steady stream of fuel must be obtained from space. So the existing hypothesis about the formation and evolution of the Solar System has serious defects. Thus the author has studied the formation of the Moon, the Earth and the Sun, and discovered the formation of the Sun and the real source of star energy. The author could also explain many solar activity phenomena such as sunspots, flares, prominences, etc.
