"Do you know, Lady Eileen, I'm often shocked by the sheer immensity of space and time. I mean, when you consider it - time that never started and will never end. Space that has no beginning and no boundary. Or - do you think - maybe in a universe that is defined by the gravity of its own constituents, both time and space are bounded and finite - as if we lived on the inside of a 5-dimensional bubble? So I apologise - he! he! - if I appear slightly daft sometimes, but there's a lot to consider."
I'm going to have to think this one over.
