Dark Matter — "Alternative Gravity" Team Responds

An anonymous reader writes, "Following previous results, an international team of astronomers answers, defending the case for a modification of the theory of gravity. This article presents an alternative to dark matter and states constraints on the neutrino mass. In short, dark matter is still not a necessity, provided that neutrinos weigh 2eV. This is allowed by what we currently know and should be tested in the KATRIN experiment in 2009."

Dark Matter is the 21st century's ether.

Dark matter is the 21st century's ether in one, very specific sense: it permeates all of space.

After that, the two differ greatly. The ether was the transmission medium for light; dark matter (obviously) isn't. The ether provided an absolute inertial frame of reference; dark matter doesn't. The ether was almost perfectly uniform throughout space; dark matter very much isn't. I could go on, but you get the point.

Basically what I'm trying to say is that statement seems true at first glance, but don't think it's that simple.
