By not artificially limiting themselves to the alien explanation, scientists have been able to learn astonishing things that in many cases could not have previously been imagined. Here's an example:<br /><br />Earth is not the most volcanically active body in the solar system. Io is. That was discovered when a woman working on the Voyager project, collecting the newly downlinked images during the Jupiter flyby, noticed something quite remarkable, definitely anomalous, and certainly unexpected: a luminous object rising over the limb of Io's dark side. It turned out to be a volcanic plume, and if memory serves, it was from the volcano now called Pele. She didn't know what to make of it at the time, but as the Io images were studied, it became clear what was going on. Yet if she had not fortuitously noticed that plume, and not artificially limited herself to the notion that it might be an alien beacon, we might not have known about Io's vulcanism until the Galileo mission.<br /><br />It is not the investigation into anomalies that bothers me. It's the willingness to discard all explanations save one that bothers me. Hoagland criticizes NASA for doing this, and yet he does it far more than they do. He *assumes* that if something is anomalous, aliens must be involved. Maybe he's right, maybe he's wrong, but we won't find out by jumping to conclusions or becoming acrimonious to those who point out other possible explanations for a given feature. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
