But if they did turn it off, when they turned it back again everything that was there before would be back, including the memory of having turned it off. Other than the realisation they they had periodically ceased to exist (or only existed since they last turned it on..) there wouldn't be a great difference. That said, the black sphere would cause the "top" to diverge anyway at that point, wouldn't it? So it'not really in their control..
