Dark Matter may be detected via Exoplanets. All the matter that is visible to us constitutes only about 18% of the total matter that we think actually exists in the universe. We know this because when all the known mass of a galaxy like the Milky Way is taken into account, the outermost stars of the galaxies are moving way too fast given the gravitational attraction that can calculated. The total gravity would be too weak to keep these stars bound within the galaxy. When you calculate what the gravity of the galaxy would need to be in order to observe the rotational speeds that we observe, you can calculate the mass that should be there, but isn’t visible. Since we can’t see it, and we don’t know what it is, we call it "dark" matter. It does not emit any light, nor interacts with ordinary things in any way that we can detect, except through gravity. Scientists have tried detecting it in liquid Xenon baths, via sensors on silicon chips, and the Large Hadron Collider in Geneva. but so far to no avail. But in a new paper published in the journal physical review letters, Physicists Rebec
