<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The graphs I posted are on the NASA website that relates right back to this paper, and the "surprise" that they "discovered' while somehow "verifying" the idea of magnetic reconenction from an uncontrolled observation. Sheesh This industry is in trouble IMO because it's doing exactly what you're doing. It's ignoring the data that falsifies their theories, and it's already "assumed" the validity of the theory they are trying to demonstrate. They refuse to falsify any idea, even with it fails to accurately predict anything. It doesn't matter how many uncontrolled 'tests"it fails, all that is considered is what "positive spin" they might put on a negative result, and no amount of negative findings will sway them from their views since they are only trying to prove it is true, not scientifically determine if the idea has legitimate scientific merit.The THEMIS team ultimately falsified both magnetic reconnection models they began with. I'm sure they will not modify their "models" to now "predict" an accurate sequence of events, but this is called "goalpost shifting". Magnetic reconnection has failed every single "test" it has ever been put to but it just won't die. <br /> Posted by michaelmozina</DIV></p><p>You keep repeating this so everytime I see it, I will just cut n paste my rebuttal from a few pages ago:</p><p> </p><p>Let's re-examine the events as described in the paper that has been accepted for publication... again.</p><p>Actually, let's take a few quotes from the paper accepted for publication on 29 Feb 08 outlining the mission parameters.

The abrupt nature of substorm onset suggests a mengeetospheric instability, but doubt remains as to its nature and place of origin.

Essentially, they were guessing based on limited data. Hell... they even got the distance wrong in what they suggested above. That's why the mission was established. These are not predictions as you might relate them to a scientific theory. They simply provided what they considered were to two most likely scenarios. There's no false dichotomy here as you present it. </p><p>You are blatently over emphasizing the meaning of these two models. The main goal of this mission is as stated in the first quote I presented. THE TRIGGER!!! Anything after the trigger is just frosting on the cake. </p><p>Now, on to what the data collected supports. If I may summarize this as well:</p><p>The data collected recently is highly indicative that a change in the topology of the magnetic field that resulted in an acceleration of current flow 96 seconds prior to auroral intensification. This change in topology coupled with the detected acceleration at a location one-third the distance to the moon in the Earth's magnetotail is suggestive of a magnetic reconnection event as the trigger for the onset of the substorm.</p><p>Where, on God's Green Earth, do you see that magnetic reconnection was falsified? </p><p> </p> <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>
