The August 2000 Scientific American has an unusually interesting
article, which unfortunately is not on the web:
The Universe's Unseen Dimensions
Nima Arkani-Hamed, Savas Dimopoulos and Georgi Dvali
Our whole universe may sit on a membrane floating in a
higher-dimensional space. Extra dimensions might explain why
gravity is so weak and could be the key to unifying all the forces
of nature.
The main problem is that it is just a few years into this research
program, so they haven't had much time to find problems with it,
and this article is written by its advocates, who may not be telling
about all the problems.
