is brought out in this thesis. Firstly, absolute velocity of galaxy moving in cosmic is 0.6 times of light velocity in vaccum; secondly, the sun kernel may has high speed of self-spinningabout thirdly, inner pressure of the sun is not so much, and its stability is the cause of its high speed of self-spinning.
