ModusPwnd and A.T. - Your comments raise a basic fact I'd like to explore. I see the light energy or feel the heat energy from a star or a lighted earthbound globe in my room as if it only traveled from the object to my eye or skin, which is not true. I don't see the wave energy in a plane...

Txs for the direction, Duck. I perused the link and recognized that I have a lot of study to accomplish before I can ask better question. If you have a summary explanation, please post it. Txs

This is a great thread for several reasons including content and character. Thank you. I am particularly impressed with the precise meanings given to concepts like evolution, natural selection, adaptive - related concepts are not synonyms and this thread shows that. I've yet to meet an evolution...
