Maxtheknife, et. al.,<br /><br />Fine. I'll try and make my position clear. And I'll be civil. We'll see if you do the same.<br /><br />I've read Hoagland's "Moon With A View" (all five parts) article three times now (once more again last night). In fact, over time, I've read everything on his site one or more times. Additionally, my personal library is stocked with an eclectic collection of hundreds of books that range from history (my passion) to photography, Egyptology, geology, space science, Asimov, Sagan and Hancock. A bit of everything. That's the way I am. I read, I study, I consider. And I make up my own mind. <br /><br />I will not contest the fact Iapteus is an incredibly interesting object. The pictures speak for themselves. There are obviously forces at work here we have not seen before and do not currently understand. It needs further study. And study it we will - in September of 2007. <br /><br />Because we do not understand how Iapetus was formed does not mean the "answer" is that it was built by "aliens." And that is where my "disconnect" - and ultimate rejection of Hoagland, (et. al.) - begins. <br /><br />Because some hexagonal cratering has been identified on Iapetus, Hoagland leaps to the conclusion it is evidence of a hollow Dyson sphere created by aliens. Hexagonal cratering has also been identified on the Earth, Moon and Mars (among others). Unless Hoagland is contending the Earth, Moon and Mars are also Dyson spheres, that's a huge leap in logic.<br /><br />Hoagland's other argument concerning the hexagonal structure of Iapetus rests on the attached photo, which he contends clearly demonstrates straight lines in the admittedly over-exposed area. There a few things about that photo that should be pointed out. First, it was an 180 second exposure. Second, it was taken with a 1024 x 1024 CCD sensor array. Third, it was taken with the f10.5 narrow field lens. Fourth, the area in question is highly reflective, with an albedo of .6 and is contrasted with an a <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>
