One recent development in physics is a couple of separate reports that scientists may be closer to figuring out so-called "dark matter", that elusive component of the universe we haven't yet been able to detect for sure. But progress is being made: The Alpha Magnetic Spectrometer attached to the International Space Station has detected positrons (the antimatter version of an atom's electrons) that might have been produced by dark matter interactions. Also, the Cryogenic Dark Matter Search in a mine in Minnesota has recorded three events involving supercool silicon wafers that could have been caused by dark matter particles, possibly supporting a supersymmetry theory involving "weakly interacting massive particles", known by the abbreviation WIMPs (got to hand it to physics sometimes when it comes to nicknaming things).
Obviously, three events is not enough to declare a discovery. Nor is detection of greater numbers of positrons than expected--but they're interesting glimpses of what could perhaps be one of the larger mysteries of the universe.
Do you think scientists will discover dark matter for certain in the coming decades?
