From the Srimad-Bhagavatam we learn that the universe is like a tree with the roots being upwards. The pole star which is situated within the Asking question star constellation is the root. The universe is pivoting around the pole star. That is one movement. The second movement is that the sun is revolving around the universe, or as if it were going around the tree. That is the second movement. The sun is not fixed. If this is proved, then their whole scientific theory collapses.
