For many centuries it was believed that only classical Euclidean geometry could provide a correct way of mathematically representing the universe  Nevertheless, scientists have come to believe that a representation of the universe employing non-Euclidean geometry is much more useful in developing certain areas of scientific theory
In fact, such a representation underlies the cosmological theory that is now most widely accepted by scientists as accurate
The usefulness of a mathematical theory is now considered by scientists to be more important than its mathematical correctness.
