I informally review the Higgs mechanism, focusing on fundamental aspects which should be common knowledge but apparently are not, explain why your understanding of gauge symmetry breaking is a decreasing function of your reliance on the unitary gauge, and discuss some implications for cosmology (domains, dark energy, CMB cold spot).
The observed luminosity deficit of Type Ia supernovae (SNe Ia) at high redshift z can be explained by partial conversion to weak vector bosons of photons crossing large-scale electroweak domain boundaries, making Hubble acceleration only apparent and eliminating the need for a cosmological constant > 0.
Cruz et al. recently showed that the CMB cold spot can be explained by a GUT-scale texture. But following Turok's argument that gauged configurations always relax quickly, they posit a global symmetry, without obvious relation to GUTs. An observation by Nambu invalidates Turok's argument when the broken symmetry group has commuting generators. This is demonstrated explicitly in the standard model of electroweak interactions and holds generally for intermediate SSB stages in GUTs. The cold spot could therefore be due to a GUT texture, and electroweak Higgs gradients may evolve indefinitely.
