Steve Weinberg says 6 of the 10 dimensions may be curled up very tiny.
According to Ward, the electromagnetic field can be thought of as a particular code in twistor space that is preserved by twistor transformations.
This in evident in the 10D across 11D twistor-space map that I presented.
Twistors are not the whole picture. My presentation goes deeper. On page 316 of "Superstrings And The Theory Of Everything" we learn that one of the things post-modern physics has to do is re-write string theory so it is free from any particular choice of gauge or space-time slice. I may have just done that!
The book suggests that "The various theories we see around today are simply different phases of the one, unified theory" ; exactly! I read with amazement as each theory discussed in the book, fitted so readily into the structure I had written in biro on sheets of paper. A structure I visualised and tried to draw months ago.
"What is called for is a prespace description for the true origin of the string world"- exactly what I may have done!
"Then, at some particular point in... but a particular point in what? Certainly not space or time, for these are now classical, large scale things" page 317 of "Superstrings And The Theory Of Everything". The presentation I gave fulfills this!
Page 321: "To my knowledge there is no direct connection between Mandelbrot's fractals and the dimensions of superstring theory"; I show how, that now there is!
"Once we leave the world of point particles behind, it may be necessary to put on a new set of intellectual clothing" (page 321): precisely!
See page 322; for evidence that certain of the fundamental constants of nature must change with time!
p333 "For Bohm, mathematics is a relatively limited language in which to understand the universe".
P321 "In Mandelbrot's world, dimensions are no longer fixed but behave in curious mutable ways"
