I was riding up the hill this morning and the sun was being screened by Safeway, but I could still see the halo of light around it. Not to make this religious or anything. I realized how important reflections are to our survival. And by our survival I mean our eyesight. I started wondering how we measure the reflectivity of substances or even if we do. Why is the radiated information not absorbed completely by the substance? There have to be laws on reflectivity, I can't find them on the internet... kind of. Maybe I haven't looked hard enough but also maybe I want to think that I've found something scientific for which to endeavor. Also I'm becoming increasingly and acceleratingly more interested in void. It's not really void because there is no point in the universe where you would be unable to detect light or radiation. So it's not void. So what is it? Back to reflectivity. Nothing reflects 100% of the information received. Nothing is perfectly reflective.(note artistic concept) Because if it were perfectly reflective it would dissipate because it would be unable to receive any energy. Also what are the differences between the reflecting of physical waves and electromagnetic waves? Maybe the substance begins to match the frequency of the waves and then begins to emit those same waves but the energy used to change it's frequency is used and that's the loss in information or rather the change. Then since it's against the nature of that substance to vibrate at that certain frequency it returns to it's natural frequency after it has reflected the received information. Mirrors reflect heat. Someone somewhere must know why the certain material inside white paint makes it white paint because we perceive it to be white paint because it reflects multiple wave lengths of color. Someone tell me who knows.
