I completely understand that. By definition the satellite could not leave the universe and turn around for a snap. The oval-shaped sphere obviously represents the limited area from which the satellite can gather light (in a given period of time).

Sorry, at first I thought that's what it was but quickly realized that that was impossible. I mistakenly thought you had, too.

However, the question of what the universe is expanding into is still reasonable.

I agree. It does beg questions and, to me, incomprehensible dimensions.

Incomprehensible indeed.
