Can the universe become stable with a new electroweak vacuum

Click For Summary
The discussion centers on electroweak vacuum metastability and its implications for the universe's stability. Current data suggests that the universe is situated at the edge of stable and meta-stable regions, leaning towards the meta-stable zone. This observation aligns with findings from up to 3-loop renormalization group calculations, indicating convergence. The relationship between electroweak vacuum changes and the top and Higgs masses is acknowledged, but the movement of stability boundaries remains unclear. Further data is necessary to better understand the Higgs potential and the possibility of the universe transitioning to a stable state.

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?

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
