According to some theories of time, temporally extended objects have temporal parts, temporal extension is perfectly analogous to spatial extension, and time is one of four dimensions that are on a par, at least with respect to the manner in which objects are spread out in space-time.
Obviously, the question is, can I access a squirt bottle I left behind in an older temporal extension to squirt Beagle before he steals one extension of my becan? If so, can I get away?
