And the take-down of the WSJ article (including the cherry-picked and non-expert status of those researchers) is contained in that very same Wikipedia article.

Well, no. A thing that can make false predictions is called a "hypothesis." Some hypotheses turn out to be supported by the evidence and some not. Being proved wrong doesn't retroactively make it not good science.

You're misunderstanding what scientists mean when they say that a theory generates predictions. It specifically excludes re-observations of the original phenomenon from which the theory was derived. They have to be new predictions, preferably ones that uniquely distinguish this theory from what would be predicted by the competing theories.
