I think he means this Bill S ... ignore the text its from a different thing the shapes what we need.



Now flatten it to 2D and think about a orbital like a normal orbital.

At the outer part of the spiral the speed is slowest almost stopped and it gathers more and more speed as it comes in to a crunch and then it will slow on the expansion out etc (Here but imagine the whole universe doing it http://faculty.ifmo.ru/butikov/Projects/Collection6.html)

I think that is what he means ... interestingly it is sort of an old idea if I have it right ... which I am not sure if finiter knows.

Assuming I am right finiter I would call such a system a constrained 2D Rossler attractor
(http://en.wikipedia.org/wiki/R%C3%B6ssler_attractor ... 2nd image down)
You can even model it if I knew some characteristsics of the shape you want.

There are whole groups of these sorts of things that come under Lorenz mathematics (http://en.wikipedia.org/wiki/Lorenz_attractor)

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
