I've put this topic on my "book" too  The fact this didn't happened yet it's a proof that it can't be done artificially, or that, in the whole Universe, there aren't civilities that are advanced enough to do so.

But do you think "vacuum decay" is a real possibility?

Or it could be a misunderstanding in physics, humans don't have all the information.  Seems more likely this won't happen naturally or artificially.

Watsisname,very interesting video.  The future of Gravitational-wave astronomy

 is going to be quite interesting

But do you think "vacuum decay" is a real possibility?

Not really. Even if it was, the probabilities that we'll assist to such an event are incredibly small, there are events that happens everyday in our universe (like supernovae or GRBs) that are orders of magnitude more dangerous than that, but still any of them affected us whatsoever in the recent 200 million years.

That vacuum decay thing is scary, i hope it is false. 

I was having an epiphany while exploring the HiRISE images, so I decided to make a Cinematic video of a small chunk of Valles Marineris taken by the MRO a few years ago:

Or at least they are not close enough or succeeded long ago enough that a false vacuum decay bubble has had time to reach us just yet...  <.<  >.>

LoL, I hope we're not scaring him too much 

Hehe. Of all the things to be afraid of, false vacuum decay is one of the more silly ones.  Sure, it could be a real thing, but we don't know, and even if it is possible it's still fantastically unlikely to actually occur.  There are plenty of other and far more likely things that could destroy us.

Oh wait, that's not very reassuring, is it?

I am scared by the concept, not so much the actual thing, pretty similar to how i feel about black holes.

*Watsisname activates the emergency EVERYTHING'S OKAY super-happy phobia-squashing button*

*turns out EVERYTHING'S OKAY super-happy phobia-squashing button creates false vaccum decay*
But GRBs are probably more spooky, since they are probably a real thing, while probably false vaccum decay is not a real thing

No guarantee these videos are relevant in any way whatsoever.

To doomsday scenarios like the False Vacuum Decay or that the LHC might create a black hole that destroys the world, I always have the same reaction:
My life experiences so far have shown me that the laws of physics are exceptionally stable.
In other words, if the universe is viewed like a video game for example, then whoever coded it did an absolutely superb job addressing every possible bug, glitch, exception, or exploit. Never once have the laws fundamentally broken down as a system, be that when humanity broke the sound barrier, split the atom, reentered the atmosphere, created antimatter, created microscopic black holes, or formed a Higgs boson. The fabric of reality has never once ripped or unraveled due to a paradox as is so popular in science fiction. So is the False Vacuum Decay scenario possible? Sure, under our current understanding. But I put little faith in ideas that the universe has some fatal flaw in it that could lead to ultimate doom for everyone due to one silly mistake or unfortunate circumstance.

Considering the universe has been around for some ~13bil years it seems incredibly unlikely any of these scenarios will happen, let alone in your lifetime.

The longer an improbable, but not impossible event, has not occurred, the more likely it is that it happens soon.
