Relatively speaking - 13 July 1858

Odd, you know. Once again I'm telling Tommy Leaf off for being so dim (which, by the way, is his defining quality) when he turned to me and said, 

"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.
