re: http://en.m.wikipedia.org/wiki/Laura_Mersini-Houghton#section_2

Correct, but remember this Tegmark Level 2. However, with regard to the voids and anisotropic flow in our own observable universe inside our own observer-dependent causal diamond I would think Level 1 parallel worlds on our own single inflation bubble would have the strongest effect? Note none of this is Level 3. Levels 1 & 2 are Bohm material hidden variables with a super-quantum potential in Wheeler Superspace where the Wheeler-Dewitt equation holds sway in the string-brane theory mini-superspace modeling.

If the observations suggested below were ever confirmed Lenny Susskind would probably get a Nobel Prize for string theory, holography of horizons and the cosmic landscape. At least no one can now say that string theory has no observable consequences. Of course string theory can still be criticized as having too much excess baggage - too much algorithmic complexity. After all epicycles did explain the motion of planets pretty well. If you put in enough math input you can explain anything. However, the current work is very interesting and formidable although a simpler picture, like the one I have using only battle-tested Einstein GR & orthodox QM, if it could also explain the anomalies would be better. However, I have yet to explain the precision cosmology anomalies using the "simpler" model.

Observing the Multiverse with Cosmic Wakes
Matthew Kleban (NYU), Thomas S. Levi (UBC), Kris Sigurdson (UBC)
(Submitted on 15 Sep 2011)
Current theories of the origin of the Universe, including string theory, predict the existence of a multiverse containing many bubble universes. These bubble universes will generically collide, and collisions with ours produce cosmic wakes that enter our Hubble volume, appear as unusually symmetric disks in the cosmic microwave background (CMB) and disturb large scale structure (LSS). There is preliminary observational evidence consistent with one or more of these disturbances on our sky. However, other sources can produce similar features in the CMB temperature map and so additional signals are needed to verify their extra-universal origin. Here we find, for the first time, the detailed three-dimensional shape and CMB temperature and polarization signals of the cosmic wake of a bubble collision in the early universe consistent with current observations. The predicted polarization pattern has distinctive features that when correlated with the corresponding temperature pattern are a unique and striking signal of a bubble collision. These features represent the first verifiable prediction of the multiverse paradigm and might be detected by current experiments such as Planck and future CMB polarization missions. A detection of a bubble collision would confirm the existence of the Multiverse, provide compelling evidence for the string theory landscape, and sharpen our picture of the Universe and its origins.

PS Nonlocality as Evidence for a Multiverse Cosmology
Frank J. Tipler
(Submitted on 16 Aug 2010)
I show that observations of quantum nonlocality can be interpreted as purely local phenomena, provided one assumes that the cosmos is a multiverse. Conversely, the observation of quantum nonlocality can be interpreted as observation evidence for a multiverse cosmology, just as observation of the setting of the Sun can be interpreted as evidence for the Earth's rotation.

I received this on Facebook, but I don't have time now to try to read it closely as I am working essentially daily in London with Clive Prince and Lynn Picknett on a new book/TV project and I am here for another week so time grows short.

Of course the 1973 SRI - CIA meeting with me, Russell Targ, Hal Puthoff, Brendan O Regan, Dean Brown ... set up by Jacques Vallee refers to these general ideas. Curious that this popped up at this particular moment.

The general idea is to model the stable leptons as tiny extreme (non-radiating) e.g. ADM model, black hole type extended structure Bohm hidden variables that will be piloted by their attached quantum potential in the more complete model. Heidi Fern working with Jim Woodward has done some very interesting work on the radiation reaction in the classical part of this type of approach. Woodward thinks it's relevant to his Mach thruster propellantless propulsion Star Ship engine model that I have yet to properly understand.

PS on the string theory front a woman professor (Mersini?) at North Carolina has scored a triumph for Lenny Susskind's Cosmic Landscape by explaining the Arrow of Time and predicting in at least one case three major anomalies in modern precision cosmology data. More details when I have time. Bottom line is that at least one precise concept of Max Tegmark's four levels of the multiverse has empirical consequences inside our causal diamond bounded in the past by the particle horizon from the moment of inflation and bounded in the future by our observer-dependent dark energy event horizon. Both horizons are Seth Lloyd computers hologram screens and we need Yakir Aharonov's Destiny & History quantum waves to properly understand what's happening.

I explain the low value of the cosmological constant without a multiverse, without eternal chaotic inflation, without a landscape, without the need for large numbers like 10^500 and higher etc. The cosmological constant is simply advanced Wheeler-Feynman blackbody radiation from our detector-dependent future horizon that is completely redshifted down to virtual photons when it reaches us - or Type 1a supernovae in our past light cone because the horizons are infinite redshift surfaces in both directions of time. Also it explains the Arrow of Time.

hc/Lp^4 at the future horizon relative to the detector ---> hc/ALp^2 at the past detector is trivial in the retrocausal loop model that also fits Aharonov's destiny state vector.

Fractal-Flows and Time's Arrow
Leonard Susskind
(Submitted on 29 Mar 2012 (v1), last revised 7 Apr 2012 (this version, v2))
This is the written version of a lecture at the KITP workshop on Bits, Branes, and Black Holes. In it I describe work with D. Harlow, S. Shenker, D. Stanford which explains how the tree-like structure of eternal inflation, together with the existence of terminal vacua, leads to an arrow-of-time. Conformal symmetry of the dS/CFT type is inconsistent with an arrow-of-time and must be broken. The presence in the landscape of terminal vacua leads to a new kind of attractor called a fractal-flow, which both breaks conformal symmetry, and creates a directional time-asymmetry. This can be seen from both the local or causal-patch viewpoint, and also from the global or multiversal viewpoint. The resulting picture is consistent with the view recently expressed by Bousso.

Yes, this is very relevant to my current conversation with Dan Smith.
