It is past my bedtime here in California USA, but I have to mention
Louvain University Belgium's Antonio De Felice and Christophe Ringeval
(respectively with 15 and 20 papers in arXiv between 2000 and 2008) in
their new paper "Massive gravitons trapped inside a hypermonopole," 5
pages (2 columns per page) arXiv: 0809.0464 v1 [hep-th] 2 Sep 2008.
They propose that the Universe is a 4-dimensional core of a 7-
dimensional 't Hooft-Polyakov hypermonopole as a regular classical
field theory which realizes the DGP (Dvali-Gabadadze-Porrati)
mechanism. This yields a Newtonian gravitation law that can be made 4-
dimensional on intermediate length scales but is 7 dimensional at
small and large distances. There's no need for a Cosmological
constant in this theory, and spacetime is asymptotically flat with an
infinite volume in the extra diensions, confinement being done via
local positive curvature of those extra dimensions induced by the
monopole-forming fields. They show the existence of metastable
gravitons trapped in the core.
The number 7, by the way, belongs to the Fundamental Set of Probable
Causation/Influence (PI):
1) {0, 1, 2, 3, 4, 5, 7, 10, 11, 13, 26}
Since PI doesn't detect any difference between microscopic and
macroscopic domains other than those that can be ascribed to "phase"
differences (or "different Universe" differences), such a classical
and higher dimensional theory fits in nicely with PI. The Newtonian
Law is also Fundamental in PI as I've argued in the last few posts of
this thread among other places.
