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?
