Here’s something from the science desk. Over the past 2 years, I’ve been rooting for the axion. I’ve posted three different blogs about this hypothetical sub-atomic particle, and why a good number of physicists are interested in it. Perhaps the most interesting aspect of the axion from the public’s point of view is that it is a dark horse candidate to explain “dark matter”, the spooky, nearly invisible stuff floating throughout the voids of space which help to shape and guide the galaxies and their mega-families (i.e., galaxies made of galaxies).
The main contended for the dark matter crown remains the super-symmetrical “light stable particle”, one of a new family of particles that is predicted by string theory (and a variety of other high-level cosmic formulas). Unfortunately, the search for the supersymmetry family has gone into overtime at the Large Hadron Collider in Europe. It was supposed to be found in the first big run of the collider (which did find the Higgs particle), but surprised everyone by its absence. The LHC is now back and running at souped-up energy levels, seeking to blast those tricky supersymmetrical thingies out of their etherial lairds. It could take at least a year, perhaps several years, for the LHC to make a thorough scan across the energy levels that it now accesses. But if the lightest supersymmetrical particle still doesn’t show up, then a whole ‘nuther idea is needed.
The axion is one of the strongest candidates for such an alternative approach to dark matter. It was originally conceived as a way to resolve a problem with the sub-atomic strong force, i.e. the Charge / Parity symmetry problem in the interaction between neutrons and protons in the atom’s nucleus. An alternative explanation to resolve that problem has still not yet been found, so the axion might still » continue reading …
