The name of the zone itself is called "Star Light" Zone, it could be a reference to higher enlightment (a light in the sky) that we go for as we finally get over the grief and rise from it. We ascend from our greif towards englightment so that we can finally move on with our lives.

The zone itself is also themed with advance construction as well as one of the few zones that encourage Sonic to take the "higher route". In a sense, Sonic is finally over his drowning lost despair of Labyrinth Zone and can finally move on with his life by reconstruction of himself, ascending to the top of it and reaching enlightment.

I suppose Scrap Brain Zone could be more reference to Dr. Robotnik, the man that Sonic is greiving over. A bran in that has been scrapped while the zone itself sporting the mechanized look of artificial change and maturity. As Sonic Passes Final Zone, he returns to Green Hill Zone which is now truely a "paradice", another name for heaven.
