[Avodah] Kinos: Hashem as Spaceman?

[Zev Sero via Avodah]

In Kinah #7 (Aholi Asher Ta'avta), the Kalir wrote "v'nihyeita ketas 
bechalal".  To our ears this evokes images of loneliness and isolation, 
of someone surrounded by vacuum, light-years from anywhere and anyone, 
but what did "chalal" even mean to people with a Ptolemaic model (if 
that) of the universe?
