The concept of "dark" is not defined by Stan. The concept of light might be defined by the big bang conjecture of Stephen Hawking, the Cambridge professor with amyotrophic lateral sclerosis, who is a sort of kindred spirit with those of us with neurodegeneration. He decided to fiish his Ph.D. in physics after learning he had a probability of living 6 months to several years about 30 years ago. Am I remembering accurately that you are a Ph.D. candidate? Have you read any of Hawking, A Brief History of time, or seen the 2 hour BBC video of his life? At any rate, the controversy of the directionality of time which allows his non-singularity for the big bang requires mapping space-coordinates with imaginary time as the time axis. Imaginary time is not conceptualized (as I understand) but the concept of time travel and directionality of time seems to be that time is always positive. Light is elecromagnetic energy quanta or photon packets or waves (dependent upon how detected/measured) with the characteristic of mass-energy conservation e=mc^2 being Einstein's recipe for energy=mass relationship with the velocity of light involved. That c in the formula. I suppose that the string theory candidates for the Grand Unified Theory of physics might eventually come to be explainable as electromagnetic energy confined to sub-particle energy rotating in imaginary darkness that is "confinement" of light in micro-black-holes. The macro-black holes are massive cores of matter that is compressed by it's hyper-gravity to singularity in the space dimensions - therefore, drawing in all matter near them to the extent that light is drawn into the "hole" in space. Let your light shine forth. Do not hide your candle under a bushel. -- ron 1936, dz PD 1984 Ridgecrest, California Ronald F. Vetter <[log in to unmask]> http://www.ridgecrest.ca.us/~rfvetter
