http://inspirehep.net/record/21273 this is one of the articles I read and one thing had me curious.... do all these old theories around false vacuum and vacuum decay have the same probability of happening? Like chances of vacuum decay or false vacuum are really low but is this the same for all theories around it from this century and especially the old ones from the 80s like this one and many others. Also in that paper it talks about a consequence happening in a de sitter or de sitter like space-time , is our universe anything like that at all? Let me know your thoughts on this
