I have a thought experiment for anyone interested. All replies welcome: Imagine if you will, a large spherical body e.g. a moon, about the surface of which are placed many large thermonuclear devices. Deep inside the moon sits an intrepid/foolish experimental physicist. When the the devices are triggered, the surface of the moon is crushed so quickly and uniformly and with such force as to create a spherical blackhole. However the critical density is reach first, only by the 'crust' of the moon. meaning the fool/heroic physicist is, for an instance at least, completely surrounded by blackhole. It is my belief that this puts him beyond our universe. And we, beyond his. My first question is, if the blackhole then 'evaporated', where/when would our fool/hero and his/her moon's interior reappear, if at all? Although this is all highly improbable to the point of absurdity, its worth noting, that in theory the fool/hero would not be crushed by the gravitational field of the spherical blackhole surrounding him (do the vector analysis if you like), unlike anyone unfortunate enough to fall through a wormhole. Thoughts anyone?
