Any observer will always be at the exact center of the observable universe. After all, the inability of energy to escape from a black hole prevents the dispersal of energy. Entropy is thus prevented from functioning, interrupting the eternal process of the universe. It's obvious that we need to consider black holes. This question can be answered intuitively by considering gravity.
Gravity is a conservative force.
This leads to an interesting intuitive model of a black hole, viewed as an idealized process. As an idealization, regard the kernel as having a diameter in the conventional sense and the reflector as having an effective radius at some distance above the surface of the kernel. Of course, the kernel might not have a real surface, and the reflector is only a convenient way of thinking about the effect of the gravity field around the black hole, but just bear with me. Assume, for the sake of simplicity, that we can consider the material in the black hole, whether it is matter or energy, to be just material. This material can then occupy only two regions.
