Hello, I am currently doing a research project on alternative theories to dark matter. I have covered all the main candidates fairly well such as nonsymmetrical gravity, conformal gravity and MOND etc. But I would really like to include a section on how string theory or M theory could explain the Dark Matter problem. The problem is that I seem to be unable to find any papers or reputible sources on this subject, I guess it is a very vauge and unexplored area at the moment, but I was wondering if anyone new of any good links or books.
Also is it true that M-theory is no longer thought of as the 'unifying' string theory and is considered to just be another version of string theory?
Is it true that gravitons are closed strings and that only closed strings can propogate through higher dimensions? If so why?
As you can probably tell I'm not very schooled at all in String Theory...I'm still an Undergraduate!
Thanks in advance
