If gravity does seep into our world through extra dimensions, then it will produce lots of tiny exploding black holes around the points of entry

The existence of tiny curled up dimensions could also explain why gravity is so very weak. If gravity has to make its way through masses of tiny extra dimensions before it gets to us, it would considerably weaken our experience of it. Hawking has calculated that if gravity does seep into our world through extra dimensions, then it will produce lots of tiny exploding black holes around the points of entry.
