DrChinese, Mentat, Brad, thank for keeping this thread alive! I got distracted and didnt check here for several days. Mentat and Brad exactly right about metric distances increasing being different from stuff moving through space. Stuff can be sitting still and yet be getting farther apart---metric is dynamic (a solution to some equations that include matter density etc).
DrC your comments and questions are clearsighted (plainspoken too ) and I wish I had noticed what was going down at this thread, would have replied earlier.
It is mutual. Your responses help me get understanding of the subject matter as well.
