"a nemesis star is not necessarily a pre ordained event. Pre ordained implies that an intelligence is behind the stars cycle. A Nemesis star could be a possibility with the passages through the Oort cloud causing disrupted material to head inward towards earth. All part of just a regular cycle."<br /><br />ok, I that's what I wanted to say by 'preordained' - a 'regularly ocuring' event on which you could count to come and it would come no two ways about it (I think comets are quite different thing, those can come irregularly I suppose due to big orbit perturbation on sun's approach which is due to their small mass), after all don't large celestial bodies come and go on quite precise schedule, I mean you can't have that rogue body come around once after 25 mill yrs and next time after say 18 mill yrs and next again say after 22 or 29 mill yrs<br /><br />I can see that on some orbit it would bring in smaller shower of bombarding small bodies than on others but even then the mass extinction would be very regular with some 'slots' left empty (no extinction on some periods, that would still leave those extinctions based on period with some beats left out here and there, ie there would be regularity in the irregularity but apparently that is not the case<br /><br />vanDivX <div class="Discussion_UserSignature"> </div>
