Cool...but I wouldn't recommend any worrying about it, nor bothering to purchase an insurance policy against it.

I didn't see much discussion of why anyone thinks a lower energy vacuum state might exist or be reachable.

A rouge planet traveling at 3/4 light speed might suddenly hit Earth, too: but we haven't any real reason to suspect such and event, do we?

Is our need for "the world will end!" boogeymen really so dire?

> Is our need for "the world will end!"...

Consider the popularity (and profitability) of fictional works in which that threat looms large.

I'd expect anything asteroid-, moonlet-, moon-, planetlike traveling at 3/4 lightspeed to glow rather intense, thus not suddenly hitting, because visible long before impact.
