String theory and the origin of the universe—new idea, old problem
... String theory involves a number of very strange ideas. For example, the universe consists of nine or ten spatial dimensions, along with the one dimension of time.3 Furthermore, all forces arise from the same underlying force (just as electricity, magnetism and the weak force are already known to be ...
