This is kind of a Cinderella story – the story of a favorite and an underdog, in what may be the world’s most esoteric sport. The leading candidate for what might make up dark matter is called a weakly interacting massive particle, or WIMP. It gets most of the research money and most of the ink.Of course, as with WIMPs, the search for axions has also been fruitless so far, as I've mentioned at least a couple of times earlier. We just have to sit back and wait to see how this develops in the next few years.
But there’s another candidate, a bit of an also-ran, called the axion. Its profile is lower, but for Rosenberg, it just seems to fit in with how the universe works.
