We know that throughout history established ideas, that the people in their time had great confidence in to be the final end all, often turned out to be incomplete or wrong. Ideas that challenged the status quo were often first met with great resistance and closed mindedness. This is understandable, because what would be the odds that mister X would have proven all of us wrong? Yet that is exactly what happened, while of course the many times it also did not turn out to be right. I recently tried to introduce a topic onto a sub forum but it got removed because: 'To preserve the quality rating of Physics Forums, in some sub forums we require references to be from reputable sources such as credible scientific journals.' When I asked for a sub to post it in I didn't get an answer. So is there a sub forum where one can simply discuss ideas that are not yet established?
