Two Australian scientists believe they have found evidence of a parallel universe of strange matter within our own Solar System. Dr Robert Foot and Dr Saibal Mitra, of the University of Melbourne, report that close-up observations of the asteroid Eros by the Near-Shoemaker probe indicate it has been splattered by so-called "mirror matter". Mirror matter is not anti-matter, it is altogether weirder. It is somehow a "reflection" of normal matter, a sort of parallel series of particles required to restore the balance of the Universe. Sounds far-fetched - some believe so. However, experiments are underway to confirm or deny the existence of this strange, potentially significant but as yet undetected component of the cosmos.
