Stardust memories

[spacester]

Stardust was intended to get data to help us understand the origins of our solar system.<br /><br />Regarding Solar System formation, if a person wanted to understand the current theory, be aware of alternate theories, and read a nice discussion of how the early Stardust data reflects on those theories, one might suppose this would be a good place to go. So far, one would be wrong in that supposition. Perhaps the third time's a charm?<br /><br />I'm gonna feign some ignorance in the interest of getting a good discussion going and I'm gonna ask a simple question or two. I am also going to ask everyone to leave their baggage at the door here. I don't know or care about how many threads y'all have done on this subject. Let's start from scratch, and I for one am much more interested in getting an overall grasp (as indicated above) than in any agenda.<br /><br />The matter that the solar system is made from came from somewhere else, right? Current mainstream theory has that blob swirling around and coalescing into a star and some other stuff, right? So why is it a surprise that some comet particles were formed in high heat? My simple conclusion is that these particles were formed elsewhere (in a star?) and became part of this comet without being some of the Sol-making stuff.<br /><br />I take it there are two "sides" to this discussion. I am interested in hearing simple explanations from both and possibly other viewpoints. If you have an 'alternate theory' then explain it. If you are 'mainstream', explain that too please.<br /> <div class="Discussion_UserSignature"> </div>

With all due respect, the moderators may want to move this thread to the Phenomena forum, as it is bound to involve a fair amount of speculating. I understand that that is the place for such free speculation. <div class="Discussion_UserSignature"> </div>

No, you can speculate here. It just depends on how scientific we all want to be about it. spacester is starting this off soliciting scientific speculation, so it should be fine here.<br /><br />It seems reasonable to my layman's mind that these minerals could predate the formation of the solar system, but then, I don't know what it takes to destroy these kinds of minerals. Would the accretion of the solar system destroy the minerals? Perhaps it would only do so if the accreting body was sufficiently large? Thus, these small bodies might preserve fragments of the primordial dust cloud, which would itself be comprised of bits of whatever came before.<br /><br />How would one go about dating these specimens? (I know, I know, ask it nicely and bring a bunch of fresh roses. <img src="/images/icons/tongue.gif" /> ) Seriously, is it possible to get an accurate date on them? <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>

Well Calli, I can only conclude that the participants in this discussion - the vaunted moderators included - are more interested in fighting their stupid little fights than in explaining things to others. What else can I conclude by looking at the other two threads on the subject?<br /><br />I've had it with this place. It is clear that speculative discussion here is no longer possible at the level it once was. Therefore my work here is done.<br /><br />Over 5 years after I started . . . .<br /><br />I'm outta here . . . <br /><br />buh-bye <div class="Discussion_UserSignature"> </div>
