So, I've heard quite a lot about this the last weeks thanks to the upcomming pb-collisions at LHC later this year. And I just thought I'd run this by you, since the answers I've gotten from other sources are far from comforting.
So basically, the theory states that we might be living in something called a false vacuum (i.e. not the universal ideal state) and that a violent collision or such could cause a phase transition into another vacuum state, preferably a true vacuum. But why do some, like Wagner/Gorelik/Plaga seem to believe that LHC could cause such a transition?
I know that this has been discussed before, in my other LHC-thread, so I'm sorry that I bring it up again. But I thought the discussion might be more suited for the Q&A section.
So anyhow, wouldn't more energetic events, like GR bursts or such, be much more likelly to cause a phase transition?
And one other thing I thought about, that I haven't seen discussed elsewhere. Is there any possibility that vacuum bubbles of any kind could be created without causing a propagation of the "inside" vacuum? Kind of like the BEC which is harmless in the unstable configuration but would be quite the opposite if stable...
Finally, and this might be a really stupid question, but what happens to the particles after a collision? I mean, wouldn't excess particles pose a danger or at the very least alter the outcome of the oncomming collisions?
