I'm not sure if this thread should go here, or in GD (please, someone, move to its best home, if necessary). http://www.bautforum.com/index.php", in intention. Most "space and astronomy" questions that get asked there are handled well, I think. However, a great many physics question that get asked there are not. For example, check out the http://www.bautforum.com/showthread...ething-huge-suddenly-accelerated-disappeared". But that's not what this thread is intended to be about. Rather it's about a thread entitled http://www.bautforum.com/showthread.php/104852-Is-BAUT-s-Q-amp-A-section-becoming-intimidating" In that you may see something that I find quite worrisome; namely, anger and denial directed towards those who try to explain that there are limits to "what if" physics questions, who point out that certain questions, as asked, are meaningless or nonsense. To me this seems to reflect a profound misunderstanding of the nature of science, and physics in particular. Worse, an apparent unwillingness to even try to understand it. So, to my questions: Do you, members of PF reading this thread, find something similar, out there in the internet? To what extent do you share my puzzlement at EDG's apparent inability to grasp the meaninglessness of the key question under discussion there? Have you come across similar cases, where you have been quite unable to get across some fundamental characteristic of physics? Have I, do you think, completely misunderstood the situation?
