For example, here's several statements from the TEM site that illustrate why I find that there is data that will not be accepted:<br /><br />RCH: <i>… limb fitting of Voyager data shows that the shape of Iapetus can be described by an ellipsoid with half-axes 750 km X 715 km …. However, note that Iapetus’ shape is irregular rather than ellipsoidal … measured radii vary between 700 km and 780 km. An irregularly shaped, Iapetus-sized body is something quite unusual in the solar system [emphasis added] ….</i><br /><br />It's limb(s) as imaged are irregular as Iapetus is a quite battered and gravitationally stressed body. That is not, per se, evidence of artificiality by any means.<br /><br />RCH: <i>As stated earlier, natural solar system objects larger than about 250 miles across are round! The physics behind this is very simple: unless they’re made of high-strength metals (like iron), the self-gravity of any object composed of ordinary “silicates” (rock) above a certain size will crush all the “edges” down into a ball. So, how do we know that Iapetus is not made of such “sterner stuff” (I mean, some meteorites are iron …), which could then support much higher, “hundred-mile-long edges” -- even against the 1/40th Earth’s gravity calculated for its surface?</i><br /><br />Amalthea is extremely irregular, having dimensions of about 270x165x150 kilometers in diameter. Pallas has an average diameter of 608 km, and is irregularly shaped; Hygaiea has an average diameter of 450 km, and is irregularly shaped; Vesta has an average diameter of 538 km, and is irregularly shaped...<br /><br />RCH: <i>Cassini observed a dramatic, sudden INCREASE in received signal strength … as this first radar program on Iapetus was being automatically executed by the spacecraft. <br /><br />This would have occurred as one of Iapetus’ “flat panels” -- because of the “moon’s” rotation, coupled with the spacecraft’s motion -- approached ~ 90 degrees … relative to the receding NASA spacecraft radar. <br></br></i> <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis: </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>
