The universe is governed by four physical forces: gravity, electromagnetism, strong nuclear force and weak nuclear force. However, there could be a fifth. This force is not known for the moment, but if it existed, it would help explain an important hypothesis of astronomy: the existence of dark matter. According to astrophysicists, the movement of galaxies cannot be understood if there is only visible matter. But if there was a 'dark' matter that is not seen, we would understand. And there comes the fifth universal force, which would be the force that governs dark matter. This is confirmed by astrophysicists analyzing the cluster of stars Bala.
