I have been reading about Verlinde, and if what he says is true that is very exciting, but how is it a better explanation?
A few important parts quoted from the article:
The outer regions of galaxies, like our own Milky Way, rotate much faster around the centre than can be accounted for by the quantity of ordinary matter like stars, planets and interstellar gasses. Something else has to produce the required amount of gravitational force, and so dark matter entered the scene. Dark matter seems to dominate our universe: more than 80% of all matter must have a dark nature. Hitherto, the alleged dark matter particles have never been observed, despite many efforts to detect them.
According to Erik Verlinde, there is no need to add a mysterious dark matter particle to the theory. In a new paper, which appeared today on ArXiv.org, Verlinde shows how his theory of gravity accurately predicts the velocities by which the stars rotate around the center of the Milky Way, as well as the motion of stars inside other galaxies. 'We have evidence that this new view of gravity actually agrees with the observations,' says Verlinde. 'At large scales, it seems, gravity just doesn’t behave the way Einstein’s theory predicts.'
