Dark blunder

So, you know when you accidentally misplace 83% of the mass of the Universe? Wait… what?

Ok, let me backtrack a minute. Do you remember last month there was a press release from ESO saying how it a study had found results suggesting that there was no dark matter after all? Well, as it happens, it was there all along. How embarrassing!

The paper is available on arXiv, and is best picked over by people more knowledgeable about dark matters than I. I think I might stick to news about baryons in future… (I blatantly won’t though, because dark matter is fascinating stuff.)

It should be noted too that the second author on this newest paper is a man called Scott Tremaine. To quote a friend of mine directly, he literally wrote the book on Galactic Dynamics.
