When it comes to obscurity you need to refer to groups that moniter it The scientific community depends on skeptical organizations to do that work  In my work as an astronomer I get reams of letters describing crackpot idea after crackpot idea I dont have time to respond to each and every one of them There are only a few people that spend time dealing with such issues Phil Plait is one of them Ned Wright is another but theirs is a hobby  not a full time endeavor  The fact is that most people in astronomy or cosmology who have heard about these ideas dismiss them outofhand The few that do criticize them do so rather handily  often without looking back even though the Against the Mainstreamers continue to retort and comeback with crazier and more shrill ideas Even the plasma cosmology proponents get in on the act  Eric Lerner has literally shouted down people at conferences Scientists have better things to publish than criticism of Halton Arps work  So thats where we stand  the references are by ommission and by way of obscure attacks in the literature We report all crackpot ideas in Wikipedia but fairness dictates that we call them what they are
