The question is what does the area that surrounds the ellipses represent in terms of observation?
To paraphrase Dick Cheney - and may I be forgiven for doing so - "I know what I see, I know what I can't see, but I don't know what I can't see, I can't see.'
We know we can't see dark matter, but know it's there - but there is stuff beyond the bounds of our imagination that also exists.
Indeed. I read it differently, though. Maybe I saw too many Venn diagrams back in school, but to me that implied that 'what can be observed' is part of 'what could exist, but doesn't'.
