To: Bruce Camber

Dear Bruce Camber,

Thank you for the invitation to comment.   Without seeing your  scheme, it is hard to judge whether it would make sense.  If I take your three questions literally, the answer is No to all three.

1.  Since space has three dimensions, the number of points goes up by a factor eight, not two, when you double the scale.

2.  The universe we live in is not nested at all.   On the
contrary, larger levels of structure are quite different from smaller  levels. Larger levels bring qualitatively new structures. For example, a galaxy does not look like a big star, and a star does not look like a big planet, and a planet does not look like a big elephant, and an elephant does not look like a big bacterium, and a bacterium does not look like a big atom.

3.  I don't know any recent work that would be important for your project. There are plenty of new pictures for you to choose from, both in the large and in the small, from galaxies to viruses.

Sorry I do not have any more useful ideas. I will be interested to see what comes out of your project. 

Yours sincerely,

Freeman Dyson
