I see the universe as never ending, but fail to understand why. We are expanding, but what are we expanding into? I'm not applying any kind of fact to this thought, because there is none. This is me digging into speculation bigger than the universe. The S structure, I think, would be one of many possible ways that the multiverse could exist. If that multiverse were in the form of an S, on a scale larger than our universe, then the curvature in the S would have to consist of a material (be it a vacuum that contains our vacuum or paper confetti that Jesus scattered around before we started this big story, whatever) that had absolutely no charge for our universe to be able to flow the way we see it today. By flow, I mean enlarge itself. Our universe is expanding at an increasing rate, correct?</p><p>&nbsp;</p><p>I think I may have confused you with my electrical - mass statement. Still again, we are in my realm of speculation, so try and keep up. When I consider chemistry, I see that molecules can combine to create new structures. We can create water by combing the right amount of hydrogen with the right amount of oxygen, etc. H and O become H2O. When we create Ozone today, it's normally done by electrocuting oxygen so that it bonds with a 3rd O and becomes O3. When we clone things, we zap a cell with electricity and force it to take on another cell. This is all broad, but still, electricity can play a role in combining of bare elements of our universe. So, we see lightning in our atmosphere. That lightning naturally produces Ozone in our atmosphere, which naturally cleans our planet. There again, we're creating something by electricity, but the reality we live in is doing it for us.</p><p>&nbsp;</p><p>Is it possible that our universe is taking that a step further? Could the universe itself be altering the chemical makeup of what we can see and understand to form things it may be lacking in other areas? For instance, if a nebula was forming a star and that star needed more hydrogen than was available, could the universe know (yes, I know where you're going to take that, so don't) that it needed that hydrogen, and convert some other abundance to hydrogen?</p><p>&nbsp;</p><p>When I was refering to electricity, I got wrapped up too much in my own field. When I say opposite, I mean that loosely. There is no opposite to hydrogen, I realize, but could that bare element be changed into something else?</p><p>&nbsp;</p><p>I think the best way to think of this is by creating a new Periodic Table of the Elements in your mind. Only this time, we're not using Oxygen, Hydrogen, etc, but we're using Quarks and Gluons... the things that make up the things that form that hydrogen. Could the universe manipulate matter on that scale so as to be able to create it's own, different object?</p><p>&nbsp;</p><p>I think, if memory serves, the reason for me asking is that the current theory is that our universe is expanding at an increasing rate and that there was a set amount of mass in this universe to begin with. If that's the case, then the universe is expanding to it's own peril. I just can't get past the fact that this perfect plan that's unfolding in front of us can have a flaw that huge.</p><p>&nbsp;</p><p>I guess I'm just trying to see past that. I may be confusing you guys, and I may be completely off what I thought I read a few weeks back. I tend to do that sometimes because I read too much.</p><p>&nbsp;</p><p>I hope I clarified what I meant a little.</p><p>&nbsp;</p><p>Will </p>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Agreed completely with DrRocket.&nbsp; That was terribly poor science at best.<br /> Posted by yevaud</DIV></p><p>That's all it was, at worst case it was a naive statement on my part.&nbsp;&nbsp; Give me a break, not everything I say is a "conspiracy" yevaud. </p><p>I hear you about the differences in energy states but IMO, all that extra energy is going to do is result in a faster (and more complete) break down of protons into subatomic particles.&nbsp; Rhessi observe neutron capture signatures from coronal loop activity suggesting P-P or other types of fussion can occur inside a coronal loop.&nbsp; Rhessi also observe also gamma ray emissions from positron-electron anihillation.&nbsp; These are definitely "high energy" collision events. </p><p>As for the rest of DrRocket's rant, it's just an obvious and blatent attempt to manipulate my statements in an effort to get you to play the role of executioner in his little "burn the heretic" melodrama yevaud.&nbsp; It's getting old to have him take every statement of mine out of context and go off on an EU rant. Why is he constantly being allowed to break exactly the same rules I'm being forced to abide by?&nbsp; Why can he mention EU theory (derogatorily) in every post when I can't even mention it, or anything even remotely associated with the idea? </p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>http://lheawww.gsfc.nasa.gov/~reames/gsfc3.htmlThis link states that protons in a CME can be accelerated up to 20 GeV.&nbsp; I've also read that particle collisions in CME and flares can create antimatter, so high energy collisions are taking place.&nbsp; Just not nearly as highly energetic as colliding two hadrons at 7 TeV (which, sadly, we haven't seen yet).&nbsp; Even if we use the Tevatron as a comparison, it's still not close by 2 orders of magnitude.I don't think MM was trying to inject EU theory here.&nbsp; Just making a poor comparison. <br /> Posted by derekmcd</DIV></p><p>I believe that article was written before the January 20th, 2005 event, but I agree, there is a very large different in the energy states.&nbsp; I guess the collider experiments you pointed me towards a few months ago between positron and electrons and the subatomic pariticles that were found in the types of colliisons, and the other collider experiments that have been done thus far, would lead me to believe that any sort of proton collisions we might observe in LHC would most likely result in a powerful shower of subatomic particles, not some new form of matter.&nbsp; Then again, that's why I suppose the LHC experiments since I'm only "guessing" based on what I've seen thus far in less energetic collisions.</p><p>I do in fact hear you about the differences in energy states.&nbsp; I stand corrected.&nbsp; FYI I appreciate the fact that someone around here is willing to have a regular conversation without manipulating my statements.&nbsp; Thanks. </p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>
