Many of your blog readers all [too] casually say that no one has figured out how the image was formed and that in this day and age with all of our modern scientific knowledge and technology this is a powerful if not convincing argument for authenticity. Strong ignorance is not strong evidence, however. No one in this age has figured out if there is but one universe or if certain biological mechanisms are too complex to have evolved naturally. What is thought about these possibilities by even the best and most brilliant scientists is subject to revision. What we may learn may delight or dismay.
