Is There a Chain Reaction?

If this quantum event happens at one point in the universe, then that bubble expands at about the speed of light and just destroys everything in the universe. And because it's happening, it would speed of light. You don't see it coming by the time the signal of it gets to you. But on the other hand, you wouldn't feel it because your nerve impulses don't travel that fast. The space in there is fundamentally gravitationally unstable and so you immediately collapse into a black hole. Man, you get it from every direction. Exactly.
