Imagine pointing your starship at your friend's star system, pressing "go", and then accidentally enveloping them inside a black hole when you decelerated upon arrival. Bummer. I'd never heard of kugelblitz! That was great. I've thought about the absurd amount of exclusively bosonic energy density that would be required to make a space-time singularity, but I didn't know there was a name for it :).
