Dark Matter – fact or fiction

The science of dark matter – or the theory that such a thing as dark matter is a real life fact is in the news – see www.physorg.com/print239281623.html. Is anybody getting close to finding out what it is? The pieces then goes on to say dark matter is invoked to balance the mathematics – within a set of formulae which are already straining credibility by telling us 96 per cent of the universe is invisible and undetectable. However, dark matter also explains galaxies and galaxy clusters, it is thought. A link is provided to a paper at arxiv which has put together a comprehensive review of current dark matter science.
