Contrary to what physics (and common sense) teaches us, does not destroy the Earth when spawned. Just sucks anything it can towards itself. And destroys it. Has a rather large, but limited area of effect. Does not seem to affect buildings. Disappears in a few seconds. However, in SS, it will expand and cause an apocalypse after a few seconds. In conclusion: useful and fun. Unlike a nuke, can be survived if spawned carefully and/or far away and/or by placing it where solid ground is between it and Maxwell.
