In 2007, Mersini-Houghton proposed that the observed CMB cold spot was "the unmistakable imprint of another universe beyond the edge of our own", just as she and her collaborator had predicted in her theory 8 months earlier.
In November 2008, a NASA team led by Alexander Kashlinsky observed the Dark Flow of galaxy clusters in the universe at exactly the velocity and alignment predicted by her  earlier in the 'Cosmological Avatars of the Landscape I, II' papers in 2006.
In the same year (2006) WMAP reached agreement with SDSS experiment, that the overall amplitude of fluctuation is less than 1. If these observational findings, predicted in the 2006 papers by Mersini-Houghton et al. are confirmed over the next few years, then they may offer the first evidence of a universe beyond our own. Such confirmation would tie the standard model of cosmology into a more coherent picture where our universe is not at the center of the world, but part of it.
After the observational confirmation of the three predictions (the Void, Dark Flow and Sigma8) her work continues to attract international media attention, GCHEP/UNC, in the New Scientist, Bild der Wissenschaft, Scientific American, and Discover magazine.
Two astrophysicists reported recently that they have found evidence of the northern hemisphere void in analysis of WMAP data.
Though I'm still curious about those multiple rings found in the CMB 2 years ago which indicates our universe may have "restarted" multiple times. Unless that has been debunked too?

If Our Universe truly is the result of the colision of two other Universes or "bubbles", this means the energy created during the Big Bang was a transfer from the two others, creating incredible heat loss everytime such creation occurs. If all the Energy inside our own Bubble comes from these two other Bubbles, this clearly is a rise in Entropy in the MultiVerse or the main Universe where all the bubbles are created by collision of other bubbles. With time, this means the multiverse is subject to Entropy just like our own Universe is doomed to lose all of its energy able to do work via heat loss. If there is rise in Entropy in the Multiverse, this means that there is time in the multiverse and that there was a begining at wich Entropy started from. Now, I suppose we could say that the entire multiverse is only a Bubble of its own in an even bigger Bubble, but a begining must have occured at some point. We just pushed it back.
