If rods are as ubiquitous as it would seem they are, why is their existence not generally accepted? Justification for the existence of rods requires that four basic claims be proven or at least shown to be reasonable:

1. There should be zoological precedences for the existence of undiscovered insects up to a meter in length. New species are being discovered all the time, so I think we should grant this one. It's certainly possible that there are undiscovered flying creatures a meter in length.


2. We must accept the existence of creatures that are invisible, although they're up to a meter in length and perhaps up to several inches wide. Discounting microscopic organisms, the natural world offers no better than transparency, such as that found in some species of jellyfish. Transparency is not invisibility. Supporters of rods have not proven that invisibility in the animal kingdom is possible, and they will need to do so by presenting an invisible animal.


3. Certain images must be visible only in the output of all types of visible wavelength cameras, but not visible to the naked eye. When cameras output their images to the final medium, be it film, paper, or a video screen, we see their output because our eyes see the same visible wavelengths that were recorded and output. We're not talking about thermographic or other non-visible-wavelength camera technologies here, so rod supporters will need to prove that all standard cameras can convert certain invisible wavelengths into visible ones, without affecting the visible wavelengths; which is something those cameras were not designed to do. Only with this proof can it be reasonably accepted that it's possible for a camera to see something that was invisible to the photographer.


4. Even if all of the above can be substantiated, there needs to be a lack of a more likely explanation. If a simple procedure can be shown to easily reproduce the appearance of rods on camera, then we haven't even established that there is a phenomenon to be investigated.

very good explenation. i would love to believe in rods but you gotta ask the question, if their everywhere then where are all the corpses?
