Note: This post is a split continuation from the thread "Cosmolgy/No dark energy?" Well, I personally try not to post my ideas as a "polemic against mainstream theories," but sometimes merely posing a thought will tend to come out that way. What better way for a blind man to define a room than to beat against the walls? I feel there is a responsibility for us crackpots to listen to the expert opinions and attempt to learn from them, but to not ask questions or pose concepts for fear of being ridiculed simply leaves us uninformed (read dumb). Isn't the mission of PF to educate? Must education be a one-size-fits-all paradigm? BTW Garth, you're signature is especially enlightening and I think they are good rules of thumb.
