Abstract: Open questions in particle physics include the precise nature of the Higgs sector, the identity of dark matter, and the origin of the matter antimatter symmetry of the universe.I will illustrate how ideas from early universe cosmology and alternative cosmic histories enrich our attempts to answer those fundamental questions and bring observable tests of new physics beyond the Standard Model, in particular through the promising gravitational-wave messengers.I will discuss the nature of the electroweak phase transition which is an emblematic example of the complementarity between colliders and gravitational-wave observatories, and the phenomenology of more hypothetical and very high energy symmetry breaking events that can lead to striking gravitational-wave observable signatures.
