Science-advisor review

Why would you assume that matter produces pterbation to the R-S vacuum metric?  Remember assumptions make an ASS out of U and ME.

I also have a problem with your idea of gravitational forces between point particles on the brains in a Randall-Sundrum two brain model.  I think in this type of medium you need to use proper and precise terminology and spelling, we are all scientists here so lets call a spade a spade and point particles on the brain "axons".  "Brain bending"? more like "Crazy"!

Also I think we can be relatively sure that any gravitation between brain particles will be small.  Real small.  Have you ever heard of "G = (M1 * M2)/d^2?  It is called highschool open a book you retard.

P.S. 

I believe you mean "$S^1/Y_2$ symmetry"
