| contents | We discuss new ideas that the Standard Model might be emergent with connection to electroweak vacuum stability and related consequences for cosmology. In this scenario, the gauge symmetries and particles of the Standard Model would be ``born'' in some phase transition at a large scale about $10^{16}$ GeV with the Standard Model parameters constrained by the requirement of vacuum stability.Emergent gauge symmetries are well known in condensed matter physics. Perhaps the Standard Model might also be emergent. In this case the particles would be the stable long range excitations of degrees of freedom that operate above the scale of emergence. The dark energy scale comes out with similar size to the tiny masses of light Majorana neutrinos. The emergence scenario comes with interesting constraints on possible dark matter structure. New physics at energy scales around $10^{16}$ GeV might be explored through its effects in the neutrino mass matrix plus using high frequency gravitational waves and polarisation observables in the cosmic microwave background. |
