Yes, that is one of the other mechanisms for creation of black holes. Not to scare anyone, but gamma ray observing satellites "see" about 1 huge gamma ray burst per day from varying, but so far safe, distances. The question of what causes these is debated. One postulated source is the "death" of a black hole. If one occurred close to our solar system, we would be fried.
