for a laugh, here is the British tabloid take on it - the not-funny thing is that people apparently read this stuff.

Anyway, back to the thread.
Allan, quantum physics is based on statistics - you need energies and probabilities to characterise what is there, so evidence of a large particle and knowledge of how often it is produced tells a lot - not just about that particle, but about the validity of the model used to describe all other particles. Dark stuff clearly indicates that there is a big hole in our knowledge - getting the models right will help determine what dark stuff might be.
Of course, there is still a very good chance that the particle is just a statistical anomaly - but even that knowledge will be very valuable in determining which models work best.
