Relative sizes

Stephen Hurrell notes that:

Since this is a question of relative sizes, I'm sure there's a
McLoughlinist explanation. I would venture, in the spirit of J.McL., that
this apparent phenomenon is merely relative, since as we all know the
Universe has been getting larger. Therefore, modern creatures might
actually be as large as dinosaurs on some completely unavailable absolute
scale . . . but relative to the size of the Universe, they're much smaller.
