You make a good point. Admittedly it's still difficult trying to grasp the idea of other worlds- [Let's not even get into "dimensions" and "galaxies."] but I'd be curious about that as well. It wouldn't be incredibly surprising, though at the same time if any other worlds out there were exactly like this one - being a prison - that would be rather sad.

A bird, maybe? How beautiful though! Such a stunning display!
