Could you have a black hole of several hundred pounds? I always thought they needed enough mass to create a gravitational field strong enough to 'suck in' light. Unless with a several hundred pound black hole, it just had a really small event horizon.

Does anyone know what causes a tiny black hole to collapse? The whole idea of black holes I find very interesting, despite my lack of knowledge about them.
