Can "particles" or "strings" in the higher brane infuence our brane? could it have someting to do with the missing dark matter or dark enery? If gravity is the only force to efffect outher branes then perhaps things in the higer branes effects us? Of course how can you prove the a things in the higher brane you can't detect is the reason we have dark matter end energy :-)

Mmmm.
found this on the webb
http://www.nature.com/nsu/030407/030407-1.html

"Dark matter, as its name suggests, does not reflect light, and rarely, if ever, interacts with visible matter. In fact the only evidence that it exists is its gravitational pull on light and stars. "Dark matter leaves its imprints everywhere, but we still don't know what it is," says physicist Chung-Pei Ma of the University of California, Berkeley."

I find it intresting that gravitios perhaps leaves our brane, and perhaps gravitos comes to our brane anf that is the reason we there is dark mater and dark enery. Please can someone calculate if the dark matter and/or dark energy match the differece in stength of gravity and the outher three forces?

Hi Neotrekkie!
Paul Steinhardt from Princeton discusses this possibility in his papers about the cyclic model of the Universe. The papers are easy to understand, and you can find them on his website: http://feynman.princeton.edu/~steinh/
