Plot thickens in hunt for ninth planet
Bioengineer: Harsh Mathur, professor of physics, and Katherine Brown, associate professor of physics at Hamilton College, reported that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies. When they plotted the orbits of the objects from the Planet Nine dataset against the galaxy’s own gravitational field, “the alignment was striking,” Mathur said.
