Black hole (InstanceTopic, 7)
From Compile Worlds
A black hole is a rather fearsome astronomical object. Taken at face value, they have infinite gravity and can suck in anything that's close enough. An explosion with roughly three times the force of an H-bomb would supposedly create a black hole, so anyone capable of manufacturing and detonating such a powerful bomb could destroy the world. If all the "little" black holes in the universe gradually expand and merge into one giant black hole this could suck up every last atom in the universe. Black holes also screw around with time and space, leading philosophers to believe that crazy ideas like time travel and quantum computing are actually possible.
