re: Einstein's theory of relativity
If I have understood correctly. Einstein said that the universe is a blanket/matrix of stuff. That there is no space. That there is no gravity. That the stars are just sitting in a depressed section of this matrix, and the earth, for example, is caught at the edge of this depression, within the blanket. Kind of like a whirlpool without the whirl.
So, how are we moving around the sun? If it is the stuff that is moving then we are all moving relative to the stuff and we would not circle the sun.
