## Abstract

Recently the idea of a Manyfold Universe was proposed by some authors to explain Dark Matter. In this study we assume that the Standard Model (SM) of particles and fields with gravity propagating in the Higher Dimensional Spacetime(Bulk) while other interactions are confined to 3+1 Einsteinian spacetime(Brane) is not due to open strings and closed loops but instead is due to the capability of gravity as the weakest and "smallest" interaction to penetrate these small Bulk size (10^{-31}m to 10^{-35}m) while protons, neutrons and other interactions stronger and "larger" than gravity do not "fits" in the size of the Bulk and remains trapped on the Brane and we present a equation to justify this point of view. Our picture relies over the geometrical beauty of the Manyfold Universe proposal that Dark Matter is chemically identical to ordinary matter but lies on other Folds. We present the fact that the exotic particles such as Photinos, Axions, WIMPS, Neutralinos etc all created to explain the Mistery of Dark Matter dont have physical existance because these were not found by a precise instrument as the NASA Chandra Satellite and NASA agrees with the Manyfold Universe and we will shall see this in the text. Also the geometrical point of view for the small size of the Bulk eliminates the need of trapping mechanisms to confine matter in the Brane based on exotic physics (eq Quintessence Fields or Einstein Cosmological Constant) providing a geometric trapping mechanism of natural beauty. Matter cannot enter the Bulk because its size is "larger" than the size of the Bulk itself. Also we "enlarge" the "size" of the Bulk from 10^{-35}m to 10^{2}m demonstrating that the Newtonian Gravity Constant in 3+1 Dimensions G_{4} remains constant and the Newtonian Gravity constant G_{5} is the affected by this "BulkEnlargement" so in our model large dimensions are not tied up or constrained by the 1/d^{2} to 1/d^{3} that in large Newtonian spaces could affect for example planets orbits and we compute the energy density of this process and although we still dont know a physical process to enlarge the size of the Bulk (and we have only a theoretical mathematical model as a "fingerprint" but perhaps rotating superconductors can provide the desired answer and we show how a rotating superconductor can "enlarge" the Extra Dimension from Planck Size to Macroscopical one) the energy density remains low and physically affordable. Perhaps if this process will be discovered someday using rotating superconductors it will be able to explore the Bulk "Superluminal" properties and produce a Macroscopic Spacetime Shortcut in the Manyfold Universe that would allow the "Hyperfast" communication between distant regions of the Universe that otherwise would be far away distant forever.
