> Imagine a bubble expanding at the speed of light bringing everything inside it under complete optimal control.

Here's a sci-fi plot idea: a bubble expanding at near-lightspeed is bringing everything inside it under complete optimal control. Lagging behind it a couple years is another bubble, also expanding at near-lightspeed - that of false vacuum collapse. Will the zone of optimal control find a way to stop the nothingness that comes just behind it from consuming the universe?
