Suppose we think spacetimes are akin to their mathematical models. Well, the models have all their properties essentially.Alexander R Prusshttps://www.blogger.com/profile/05989277655934827117noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-1308984640822740092015-03-18T09:58:28.257-05:002015-03-18T09:58:28.257-05:00I would think that there are modal truths like &qu...I would think that there are modal truths like "I might have been in Bermuda right now." But if I might have been in Bermuda, then Spacey might have been (very slightly) curved differently. So, not all of Spacey's properties are essential to it.<br /><br />Of course, you could insist that the location of every object with mass is an essential property of that object. You could also insist that, had I been in Bermuda, I would not be living in Spacey but in some other space-time, e.g. Curvey. But I don't know what would motivate those views.Heath Whitehttps://www.blogger.com/profile/13535886546816778688noreply@blogger.com
