From Robert Gifkins
Your article raises the possibility of cosmological constants changing over time. I recall reading a book by E. A. Milne that was a popular version of his cosmological research during the period from 1928 to 1950. The book was entitled Modern Cosmology and the Christian Idea of God (1952). Milne propounded a theory of relativity derived from considering time as the basis for relativistic calculations, and I think he concluded that one had to recognise two kinds of time measurement. In one time (t-time) constants appeared to be constant, but in a more cosmologically true time (tau-time) they predictably changed. I wonder if any of your readers can recall this work and could comment on whether it has been discredited or just forgotten.
