There is no electroweak horizon problem

Summary: Spontaneously broken symmetries in particle physics may have resulted in phase transitions in cosmology, such as quasi-de Sitter inflationary expansion and the separation of forces at the GUT energy scale. The discovery of the Higgs boson confirms another phase transition at the electroweak scale, but it also presents a horizon problem for current cosmology. The horizon problem suggests that the early Universe's expansion history predicted by standard cosmology may be contradicting.
