Can the universe become stable with a new electroweak vacuum

The top and Higgs mass determination arose the old discussion about electroweak vacuum metastablity. There is an interesting fact that with available data the universe places in the edge of stable and meta-stable zone tends to be inside the meta-stable region. This conclusion confirms up to 3-loop renormalization group and even shows convergence. I know that changing the electroweak vacuum propertionally changes the top and higgs masses. But what I can't realize is that how the stability and meta-stability boundaries movem in this situation. So to speak, can the universe become stable by new high energy physics emergence as just <h>=246 Gev replacement?

The annual big string theory conference took place last week. I thought I would make a thread about it, partly because the most prominent post about it anywhere, is probably Peter Woit dismissing it as worthless. I skimmed the live video (links here to slides, videos, and posters). What did I personally find to be of interest? Lara Anderson gave a talk about topology change in heterotic vacua, i.e. transitions between different Calabi-Yau manifolds in the extra dimensions, which turn out...
