But if at some level the continental motion could be described as "random" then I wouldn't hesitate to argue for some version of "time average is ensemble average" (including some variant of likely ergodicity).<br /><br />Re asteroid impact: That is a good point. But it would only argue for an "initial" unbalance not one that comes in cycles.Roberthttps://www.blogger.com/profile/06634377111195468947noreply@blogger.comtag:blogger.com,1999:blog-8883034.post-89778724487142887512017-11-10T08:11:10.472+01:002017-11-10T08:11:10.472+01:00As I've been careful to point out naturalness ...As I've been careful to point out naturalness arguments are fine when you have a probability distribution, which is usually the case in all situations where you can reasonably claim to have a statistical ensemble. <br /><br />I'm not much of a geologist, but I was under the impression the current theory for the formation of the moon is a major asteroid impact that tore off much of the not-yet-quite formed planet. Quite possibly that would have left a major assymetry? But really just guessing there. Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.com
