<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>How did they "prove" anything? All they did was "make up" a "magnetic island" and they never physically actually explained it. </DIV></p><p>For the love of God, yes they did. They gave specific equations detailing the energy gain process and all the acceleration mechanisms inherent in their idea. They performed simulations based on the idea. How could they do that(produce a model that predicts results that are then confirmed observationally) without a valid set of governing equations? </p><p> </p><p> </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Where is their mathematical model of how that's done with Maxwell's equations? Which model are you supporting again?</DIV></p><p>It is not the purpose of scientific publications to walk you through a derivation of their ideas. There are some things rightfully assumed to be common knowledge. Find me a single equation they use in that paper that violates Maxwell's equations. I only quoted two papers that directly address magnetic islands, but you are applying it to every single paper I post. It is just a possible explanation of the observed results. And it works. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> No they didn't.</DIV></p><p>Did you look at the other papers? They created reconnection events and observed that the electrons were accelerated to suprathermal levels. Now you are just accusing these scientists of blatantly lying in their papers. The events they simulated in the reactor are physically identical to what is believed to be a reconnection event. </p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> Of course the moment that the current stopped flowing in the experiment the plasma acceleration ended.How *exactly* (be specific) did they "create magnetic reconnection" in that experiment? Define the actual physics that took place on how that relates to your earlier "magnetic island" theory?</DIV></p><p>Read the paper and they tell you. No really, they do. I should not and WILL not summarize a paper you could just as easily read for yourself. You are only asking to try to discredit me because you know I won't waste my time doing it. I am not the expert. They are. It also has nothing to do with magnetic islands directly. It is just proving the idea that magnetic reconnection CAN accelerate electrons, not HOW. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'></p><p>Somehow they managed to "translate" a complete "failure" of a "prediction pattern" into a "verification" that "magnetic fields store energy" and release them during a process of "magnetic reconnection". Neither model accurately predicted the sequence of events, so how does the verify "magnetic reconnection" was involved in an uncontrolled observation?All they observed was "current flow" entering the ail of the magnetosphere.</p><p>...</p><p> When did they demonstrate a physical link between current flow and "magnetic reconnection"?Of course they did. Neither of their two models accurately predicted the observed sequence of events. Look at their graphs! </p><p> </DIV></p><p>And where did this current flow come from? Just out of nowhere? Also could you please inform us where you got those images? They are not in the Science article they published. </p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Since the series of events did not match their predictions, how exactly did they demonstrated "magnetic reconnection" was involved. I can't just claim that "invisible elephants" creates "current flow" and then use the Hall effect I observed in the current flow as a "verification" of invisible elephants.</DIV></p><p>Arguing this point about elephants is futile because you claim the events they recorded are not reconnection events. The whole active scientific community is against you on this regard. </p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>It has absolutely nothing to do with "magnetic" reconnection, and everything to do with "current flow" that comes into the tail. It is not "likely" that "magnetic reconnection" was involved in this event because both models were falsified by the observations. </DIV></p><p>Create for us, if you will, a model that can predict a substorm using EU theory. If you were capable of this, you could easily find a job here as this is the primary reason the department I work in exists. Their paper simply states that there is most likely a connection between reconnection and substorms. Tehy make no claims as to the accuracy of being able to predict other than that they believe a reconnection event will precede a substorm. They don't claim to be able to predict the exact amount of time between the two events. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Many papers do. That's the problem with all of these metaphysical theories. Nobody is quite sure about the physics of how they work. There isn't a real "consensus" on how it actually works. Nobody can "predict" anything useful with these theories and if you ask 10 people to explain it, you get 10 different answers.</DIV></p><p>And EU theory can predict substorms? Show us. I would wager that if you asked 10 proponents of EU theory to describe what they believe they would say differnet things. That is just a result of scientists forming differing opinions based on facts, which they then test and that is how they have jobs. I've been wondering lately what Alfven or Birkeland would have to say about this argument if they had access to the information we have now. I get the feeling there may be a moderate twisting of their work to your advantage. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Birkeland has already "convincingly" demnstrated that "current flow" was involved and I do not have to demonstrate to "magnetic reconnection" is false, only that their results didn't match their "predictions". </DIV></p><p>YES, BUT he did not demonstrate how the current flow was produced or accelerated. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I can't falsify ever possible"flavor" of this theory, someone has to actually do that as Birkeland did that with "current flow".</DIV></p><p>If Birkeland can falsify a theory with his experiment, why do these other empirical demonstrations not count? </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>First off, I don't have to produce anything. </DIV></p><p>With that attitude you will never get the respect or trust of the science community. They are constantly producing evidence backing up what they say. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> I don't have to show "new results", they must demonstrate that "magnetic reconnection" is somehow associated with "particle acceleration".</DIV></p><p>If you want anyone to believe you, you or some proponent of EU theory has to step up and show that acceleration to suprathermal levels is a viable model without magnetic reconnection, and subsequently back it up with observations of the signatures such a model would predict. </p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> An *old* working model has already been produced that demonstrates that "current flow" is related to aurora. A modern working duplication of Birkeland's work is unnecsssary.</DIV></p><p>I am not requesting a duplication, I feel that you are making claims that Birkeland's work did not address. And yes, I have read over what he did. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I doubt you've even read the first paper I cited on this topic, but he wrote about the Earth's magnetosphere quite extensively in his body of work and he described it all as "current flow". Anthony Peratt put his work into a computer model and they showed how it relates to cosmic plasma. It's already been done.</DIV></p><p>And I doubt you've truly read in an unbiased manner any work i've posted. My intention in posting is this thread is not to poke holes in Alfven's theory, but to show you why I and the modern science community believes magnetic reconnection exists. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>"Good science" is required. "Modern" is not. </DIV></p><p>When we speak of models, you cannot claim that old(even 20 years ago) models are equally or more valid to modern simulations. Supercomputing power has increased at a ridiculous pace(see the Roadrunner computer at LANL), and is so much more sophisticated now than people such as Chapman could have ever imagined. So when it comes to modeling, age does matter. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Birkeland's work has stood the test of time and you too are relying upon the validity of his work in the final analysis.</DIV></p><p> It has stood the test of time, but not in the sense as your interpret it. If it had, magnetic reconnection would not exist as the accepted theory. Bottom line, his theory, if you want to claim he espoused this current view of "EU" theory as people have interpreted it, has been replaced by a theory with better evidence. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>No, I don't. Proponents of "magnetic reconnection" are obligated to provide a working model of their idea just as Birkeland did with "current flow". </DIV></p><p>This statement confirms you haven't read in detail any paper I posted. If you are using "working model" as a code word for "lab experiment" then you have an unrealistic and flawed view of a working model. A working model is simply any model, whether it be mathematical, physical, or computational, that can reproduce real life results. There are models that do that. And guess what, they use reconnection. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>There are not even two papers that seem to agree on what "magnetic reconnection" really is. You've already demonstrated that point for us with the PPL paper and the earlier one you cited. They are based on different ideas.</DIV></p><p>If you are referring to the island paper, then of course they are based on two different things. One addresses whether reconnection is a valid mechanism to accelerate electrons, the other develops a theory describing how it happens. They both deal with the same event though(reconnection). That is like saying a paper on the formation of a star and another on the composition of a star are completely unrelated and claim two different things. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I haven't even seen you touch that paper on this topic from Alfven. </DIV></p><p>Been watching through my window now have we? </p><p> Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Care to do that and then tell me that I didn't rpesent "solid" arguements to rebutt these very ideas?</DIV></p><p>I am not arguing that Alfven did not make valid points. I am claiming you are misrepresenting them. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'> I simply offered you a physical model of a "magnetic island" that is based on physics and current flow.</DIV></p><p>No, no you didn't. What you did was make up a concept that was not backed up by anything. The paper I provided(Drake 2006) however does back up its model. You can't call a concept you just came up with a model without testing it. And no, Birkeland did not do this. Again, his experiment where he produced aurorae with a cathode ray were more to do with the end result, it did not address the mechanism by which his electrons were accelerated. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I already did that with the paper from Alfven that you never read.Which brings you in direct conflict with the father and Nobel Prize winning author of MHD theory and you haven't even bothered to read his work or the specific paper he wrote that dealt with this very issue in the exact conditions we're talking about. <br /> Posted by michaelmozina</DIV></p><p>You claim you recognize Alfven is not infallible but a statement like this reeks of hero worship. Like I said before, I provided you with everything you asked for. You did not request that I try to disprove Alfven's theory, you wanted evidence of reconnection. I gave you it many times over. You are choosing to ignore it, so I think we can declare this thread as dead. I have wasted far too much of my time with this argument(not in reading the papers, that was productive use of my time, but in trying to explain it to someone who is refusing to listen). On the surface your arguments appear to be reasonable, but they are merely what should be the beginning of your argument. What should follow is a thought-out explanation of what you believe. When challenged for more explanation, you just tend to not include that particular sentence in your quote-filled reply or just talk around it. This has been an entirely one-sided debate and I am done with it. I'm not going to even bother with your other thread...it is even more "out there" and I am personally insulted that you find astrophysicists to be so foolish and uneducated. Like I said, we are not just making assumptions...we have good reasons to believe what we do. The science community can't waste its time trying to disprove every "theory"(just calling it a theory doesn't make it one) out there that doesn't give solid scientific evidence. If you don't like how the science community works, then feel free to stay out of it. The way it works in reality is the minority opinion has to give compelling evidence to the majority to change their mind. You can't just sit in the corner throwing a tantrum, you have to get out and publish and get recognition and only then will youe ver be able to change the accepted foundation of science. </p> <div class="Discussion_UserSignature"> </div>
