Examining the Expected Effects of Dark Matter On the Solar System 190
First time accepted submitter LiavK writes "Ethan Siegel recently wrote a great post for ScienceBlogs discussing the expected total mass of dark matter in the solar system. As far as we can tell, dark matter only interacts weakly, via gravity, both with itself and normal matter. So, it can't collide with itself, meaning that it has no way of getting hotter and radiating away energy and momentum. This means that it remains a diffuse mess, with a density that is ridiculously low, to the point where detecting its local effects is likely to remain... challenging for the foreseeable future."

Eeeek!

Michelson and Morley found nothing, they were full of shit.
Yeah, experimenting to prove something beyond a shadow of a doubt is always just a waste of time and effort. I hear Kepler was disappointed to learn of elliptical orbits too.
