Dark matter, which contains the "missing mass" that's needed to explain why galaxies stay together, could take any number of forms. The main possible candidates include MACHOS and WIMPS, but there is no shortage of proposals. Rather, the biggest challenge is finding some evidence that would support one or more of these candidates. Currently, more than 30 experiments are underway trying to detect a sign of dark matter. So far, only two experiments claim to have found signals, with the most recent observations coming just a month ago. Now, physicist Robert Foot from the University of Melbourne has shown that the results of these two experiments can be simultaneously explained by an intriguing dark matter candidate called mirror matter.
