When thermonuclear burning can't anymore maintains a sufficient thermal pressure a star shrinks to a white dwarf, a neutron or quark-star, or even a black hole depending on its mass. Here I am interested in the black hole case. Near the BH horizon, time get ever and ever slow and get frozen at the horizon itself. This produce a curious effect : WHAT IS UP IS AS WHAT IS DOWN : A moving charge far above the horizon will be seen from far away after the usual ligth propagation delay, for example 8 mn for the Earth-Sun distance. But slowing time near the horizon will keep too a picture of the past electric field. Pilled up on the skin outside the horizon, there is all the history of the particle's electric field. A black hole is so a giant archive of the past for all nearby matter. To see the past of an object put near a BH you can look in a telescope from far away or dig out the BH skin. We are near a Black Hole ! This would have no practical interest if the nearest BH was at the galaxy center, 30 000 ligth years away. In fact we are only 6400 km from a BH at Earth center. How that ? Assume you are in a space ship going back to our world at near the speed if ligth, special relativity tells us Earth will be seen with a reduced diameter in the displacement axis. Perpendicular to thatanything will be angularly shrinken. If the Earth radius may be reduced at near 1/2 inch by relativistic effect, our world will be seen as a black hole. Because all free falling movement states are equivalent, this one is as good as our more common reference frame. We can't escape this conclusion : all the Earth past is storred in a high gravitational reference frame of our world and we can get it using ultra-relativistic phenomena. MAKING A FIDO : That past could be seen by a FIDucial Observer lovered at the relevant black hole skin level. A FIDO is assumed to be at rest as seen by a far away observer, that is he resist the near horizon acceleration. For photon, or indeed any masseless particle, all moving reference frames are at hand. What select one or another from the view point of an (nearly) unaccelerated distant observer is the acceleration of the message sending FIDO. If a photon comes from an accelerated source matching what undergoes a given FIDO, then we can think of the photon as a message sent by the FIDO. Particles, mostly neutrons, in the outreach of big nucleus undergo tremendous accelerations. They are natural communicators with FIDOs located deep in the Earth black hole skin. Before looking at an all out exploraton of 4.6 billions years of Earth history, getting back the past organization state of a corpse in cryonics storrage could be a valuable exercise.
