Birth of Universe from String Landscape

[selfAdjoint]

Here is something new and different:
http://www.arxiv.org/PS_cache/hep-th/pdf/0410/0410213.pdf. Suppose you treat the string landscape, all those vacua and potential ridges, as a LATTICE? And then use lattice physics borrowed from condensed matter research to see what happens to it? And what happens is a single stable peak with a tiny but positive cosmological constant?

I do want to encourage our discussants to look at this paper; it's not long and the deep string stuff is only touched on. Most of it is about quantum tunneling from one vacuum to another and how that affects the statistcal probability of a single solution.

Is "quantum tunneling between states" just another way of saying add these states in a quantum mechanical superposition?
