Speculations on unknown images, spectral sources, and physical constants

B. Roy Frieden

In this paper, we are going to tackle a problem which, at first glance, appears akin to describing the sound of one hand clapping. This is the problem of describing in some way an image, when nothing is known about its structure. The image cannot be seen, and no prior information on its statistics are given. All that is known is that it is an array of energy flux values. Surprisingly, this quest will reach a definite (and positive) conclusion; it will also lead us along a road with numerous exits into related fields. Major detours will be made into spectroscopy and (surprisingly) cosmology.
