Inflation and electroweak and GUT vacuum

  1. Feb 28, 2012 #1
    Before Higgs symmetry breaking of SU(2)xU(1) electroweak unified force or even before that, when strong and electroweak were unified as GUT theories propose, the vacuum was different from today's universe.

    What effects had these different vacua on the evolution of the universe?

    thanks

    You would need first to figure out what effect the current vacuum has -- the quantum field theory prediction (more like an educated guess) has been described as the worst theoretical prediction ever made in physics. Indeed, if you use effective QFT with a Planck scale cutoff, you get the magnitude of cosmological constant wrong by 120 orders of magnitude.
