Why 10^520 Universes in String Theory Landscape

[Quantizer]

I am trying to understand the connection between eternal inflation and the the string theory landscape of 10^520 possible universes

Where is the original scientific article that proposed so many false vacua solutions

If anyone can point me to the underlying equation and article that articulates there are up to 10^520 possible universes that would be very much appreciated

Btw, I have just joined Physics Forums, searched high and low in google and in these forums but cannot find any definitive answers documented concisely anywhere

Have you looked here: http://en.wikipedia.org/wiki/String_theory_landscape?

The following review by M. Douglas, one of the pioneers of the landscape: http://arxiv.org/abs/hep-th/0303194
is listed in the references of the wikipedia article.

Are you familiar with the eprint arXiv? The SPIRES high energy physics database?

I wrote this before so you can probably use some key words below to find relevant references. I have actually written a layman version. Bapowell already gave you the hint.

It has to do with the size and shape of the calabi-Yau manifold with the help of which the compactification is done. you need something extra to avoid the moduli problem for which you need fluxes, which somehow give it a definite size and it will now take energy to change the shape of the manifold. These fluxes are somekind of threading lines through the holes of the manifolds. A calabi-yau in 6 dimensions has around 500 holes,and fluxes themselves are quantized (say take value from 0 to 9) which gives around ##10^{500}## possibilities. Each one of which corresponds to different vacuum, one of which is ours corresponding to almost zero cosmological constant.

Thanks Andrien

I think this article backs what you are saying
