but what exactly is this dark matter that particle, physicists like chris john shawn and beg a are looking for in numerous experiments. physicists have already proven that dark matter exist, and that it makes up 85 percent of all matter in the universe. but they have no idea what it is made of the the search for dark matter is the search for what holds our entire universe together. 6 because without it or galaxy, for example, the milky way would fly apart the planets journey around their star, the gravitational mass of which keeps them in their orbits. stars in turn, or a bit around the center of their galaxy. theoretically, the further away of celestial body is from its center of gravity. the slower it should move. but measurements have shown that the outer stars of the milky way move much faster than expected, or calculated astrophysics explains it this way. our galaxy consists of much more matter and then what is visible. and this invisible matter or dark matter also exerts a gravitational pull one, the celestial bodies, so that they can move faster without the ring out of orbit. the re
