"Gretch" may be considered a material or an experience. The relationship between the material and the experience may have something in common with the relationship of matter and energy, although the creator of "Gretch" need not operate in the same intellectual sphere as Einstein. Currently, the original creator of "Gretch" is not known, and the name "Gretch" (which will be used temporarily until the original name is found) was formed by the author's blending of his source of information about the stuff and the nature of it. Correspondence identifying the original creator of "Gretch" will be gratefully acknowledged! Rumors abound, but the written word is elusive.
