This is never going to happen. It’s statistically impossible. Given the age of the universe, if it hasn’t happened by now, it never will.

what the hell are you guys talking about? and gimme some of what you are smoking too LooooL

The vacuum decay theory is only a weird implication of the quantum physics theory. We know today that the quantum theory is only an approximation of our universe and is not able to fully describe it. Its application sometimes results in unsolvable and illogical paradoxes. The vacuum decay theory is one of these phenomena. It is expected that new quantum gravity theory (M-theory perhaps?) will solve these paradoxes and there’ll be no room for the vacuum decay theory.

Vacuum decay is actually as common as your beer freezing instantly when you put it carefully in the freezer and then bump it, phase transitions, both quantum and classical happen all the time. There are both mundane and exotic applications of these phase transitions theories, the mundane ones are most certainly observable.

This kind of stuff seems very threatening and overwhelming first time you hear of it, but if you sit down and think a little, things don’t look that bleak anyway. There are far greater threats to us right now, like pollution and terrorism.I felt a glimpse of my own mortallity when i first saw this, but i turned it into something positive by discovering how much my loved ones actually means to me, and realized how much i want to and can do with my life.

You are surely right that this is the last thing we, with our puny lifespans, need to worry about. But in theory, such an event could have already happend Thousand of Millions of years ago. Since its propagating with lightspeed, it depends whether it happend within the observable (for us) universe, or outside. Due to inflation and expansion, certain regions may never be reached by such an event.

And recently, astronomers have witnessed 2 supermassive black holes fusing together in a collision between 2 galaxies. The impact created a gravitational wave of such power, that this new hole was kicked out of the new galaxy. If we try imagining how much energy there was involved in this process, we would probably just become dizzy. Yet it was still not enough to spark a metastability event.

If a bubble of lower energy is to be nucleated, you will have gather an enourmous amount of energy in a very tiny place.We don’t know how much, nut we can conclude that nothing has sufficed thus far, otherwise we would not be here.Just think of a supermassive black hole. A mass thousand times that of our sun bunched up in a single point, that’s a lot in a tiny place. Yet that was not enough to nucleate a bubble of lower energy.

Thus far we cannot know if we do actually live in a false vacuum. It is a possibility which scientists are definately going to explore.Is a decay going to happen in our lifetime? No.Some scientists say that it is a possibilty, but they say that no matter how slim the chance is. As a scientist if it is possible for you to win the grand price in 10 different kinds of lottery every week for the next 20 years, and he will say yes.The possibility exists, but is it going to happen? No.

Look at Wiki False vacuum”The possibility that we are living in a false vacuum has been considered. If a bubble of lower energy vacuum were nucleated, it would approach at nearly the speed of light and destroy the Earth instantaneously, without any forewarning.”
