SOURCE OF ENERGY (natural or supernatural) ... As the image is a non-contact image, we must refer to a source of energy as the cause of the body image. There are many hypotheses that are based on different sources of energies, but in some cases supernatural hypotheses have been advanced which leave the realm of the traditional sciences because they postulate a non-reproducible burst of energy perhaps correlated to the Resurrection event.

Some hypotheses, for example those based on thermal energy also has serious problems. The scorch theory is contradicted by the fact that image does not floresce while the scorch marks from the 1532 fire do. Another problem with radiation theories, much like the vaporograph theory is that the image has relatively high resolution which requires a "focusing" mechanism.
