    Kevin,Although I do not have the educational baocgrkund to make an informed decision as to whether or not the Bullet Cluster is proof that dark matter exists, I do know that there are those in possession of such a baocgrkund who claim that the Bullet Cluster data may be consistent with theories that do not include additional matter. Also, the only way we can say that we proved the existence of dark matter is if we detect the stuff directly because indirect evidence can always be subjected to the objection that there may be other explanations for the phenomena with evoking extra matter. All of the evidence is indirect and inconclusive and there are those in the community who have alternative theories for the same observations.
