Physicists have long been driven by the existence of the fifth force of nature, which is linked to dark matter, in which most of the mass of the universe is accounted for. They are searching for it continuously. Currently, they are searching it in the core of the Milky Way.
The scientists examined images of the center of the Milky Way that were taken by the Keck Observatory in Hawaii. With this, the team could trace the orbits of the stars near the Milky Way galaxy's supermassive black hole. They could also gauge the direct impact of gravity on the movement of stars.
Andrea Ghez, the director of the University of California, Los Angeles Galactic Center Group, and her team theorized that the best place to search for the hypothetical fifth force of nature would be somewhere in the universe, in which the impact of gravity is so powerful, and signs of something extra will be easy to identify, according to Science Alert.
