[/url][/IMG] I looked at the diagrams for Lemaitre's ideas and modified the labels. All similar diagrams have time as some mysterious arrow which I have changed to Imaginary time. Also, the space within the circles normally represents nothing, but in the chart, it is the expansion driven by our 'ordinary' time. Each ellipse represents a hypersphere (that is 3 dimensions dropped to leave just a circle - the circumference is the hypersphere)
NB no acceleration of expansion is shown (I think it could be misleadingly due to time dilation)
A stretch too far maybe but consistent with my other posts regarding a Quantum Landscape the surface of the expanding cylinder might be considered as the 'Quantum Landscape' modified as the universe passes in Imaginary Time.
