DESCRIPTION:Speakers: Alessandro Tomasiello (Unimib)\n\nAn expanding bubbl
 e in AdS5 has a dS4 geometry\; the dark bubble scenario explores whether t
 his can be our Universe. I will describe new realizations of this idea in 
 M-theory. The most interesting one has a flag manifold as internal space. 
 The effective cosmological constant can be tuned to small values. As one d
 oes so\, the extra dimensions grow\, but slowly: $R\\sim \\Lambda_4^{-1/4}
 $\, getting intriguingly close to current data for extra dimensions.\n\nht
