Quantum Field Theory

Source

QFT is very intriguing. Especially the higgs field. I have been reading up on the higgs mechanism and having a positive minimum value is very strange, especially where we have the electromagnetic field force always 0 where there is no excitation in said field. I have been thinking, vacuum decay where the higgs mechanism changes from its current value to a new minimum would be a very catastrophic event, perhaps big bang powerful? Since we consider the Big Bang to be the start of the universes time we believe that time began with it, however, there is a fruit for thought the big bang was actually the result in vacuum decay from another meta-stable state from a higgs value that was larger than 0 in the past. Perhaps when the universe went through Reionization that could have been the decay of some kind of quantum field. I wonder perhaps if the result of dark matter can be linked to the higgs field being a non-zero value, and perhaps the dark energy may have been the "bubble of annihilation" or the field/fields decayed and we are just interpreting things wrong.
Any thoughts? For or Against I think we could benefit from exploring alternative interpretations of the evolution of the universe. We have much supportive evidence for the big bang theory, and events throughout the evolution of the universe to support the way its in text books, however missing among all the laws and theories is a quantum gravity theory, We know that the quarks have intrinsic mass, given to it in the higgs boson, in the reionization theres no evidence to suggest a Quantum Field decay but really there is no evidence against it atleast to my knowledge.
