It may have been a clumsy metaphor for something that is completely beyond our understanding or conception (even beyond the capabilties of CGI) but I think you need to look beyond that and try to imagine what they were trying to convey.
I think I was possibly a it harsh there. Ha ha. I didn't hate the film by any means, I quite enjoyed it. Given the whole concept of space and time is pretty mind bending they dealt with it pretty well I guess.
