Quantum Black Holes
... At some instant, the sphere S emits a flash of light. At a later time, the light from a point P forms a sphere F around P, and the envelopes S1 and S2 form the ingoing and outgoing wavefronts respectively. If the areas of both S1 and S2 are less than of S, then S is a closed trapped surface. ...

... We can solve this by analyzing the energy situation. There are only two terms we need worry about, the potential energy stored in the spring and the kinetic energy when the spring uncoils and the block is released. There is no initial kinetic energy and there is no final energy left in the spring. T ...
