Wow, super interessant cet article!
So a 40% variation of a parameter of the Higgs self interaction leads to a prediction for the life of the universe from inferior to atosecons to 10241 years! lol!
Well, at least, we know it has been around for about a 1010 years... so the chances it collapses during the few million years of humanity's lifetime are small enough to not be worried...
These calculations involves a tunelling process.
Actually my question has a more classical touch to it: no tunelling, but just an event which could act as activation from one minima to the other.. Do you think that such an event would be possible?
Or would it require so much energy localised in a small region of space, that a black hole would form immediately. Black holes would be saving our universe by confining a zone with a different Higgs field potential.
Funny idea don't you think? :-)
I don't think this would be possible, but this goes slightly borderline with respect to my expertise (so that I may be wrong).
