Dwarf planet Eris may have something big in store for researchers, namely the killing of dark matter and dark energy theories. Galaxies appear to have a stronger gravitational influence than can be explained by a visible analysis, this has led to both the dark matter and dark energy theories to try to explain these anomalies.
"To test whether quantum-scale gravity is at work, Hajdukovic plans to borrow a trick from Einstein (see diagram). Due to gravitational effects in the solar system, such as the tug of other planets, Mercury's oval-shaped path around the sun slowly turns, or precesses. In the 1800s astronomers noticed that this happens at a different rate than predicted by Newtonian physics. Einstein showed that the sun's mass creates a curvature in space-time that affects Mercury enough to explain the difference, lending credence to his theory of general relativity.
Hajdukovic's quantum gravity might create a similar discrepancy with more distant orbiting bodies, he says - which is where Eris and its moon Dysnomia come in."
dark matter always seemed a bit hokey to me
