A recent study explored the understanding of relativity at an extra-galactic scale, which basically determines how gravity will behave over very large distances. To date, relativity remains the best description of gravitational attraction over long distances. To some, it was hoped that one day perhaps a shortcoming in the theory of relativity might point the way to a better understanding of the nature of the universe. As of yet, relativity has proved to be highly accurate. Now, a new study has opened up a new area of research.
