Coug are you trying to bust my balls?.....Take your best shot I've been married three times and they've been busted by the best. Bye the Bye the sky is blue because of the photons shot out into space by the sun. By the time they get here they're blue from holding their breath in the vacuume of space.

Even at the speed of light the photons get a little blue. To show you how fast light is no matter how fast you open the door on your refrigerator you never can catch the bulb off, unless its burned out. You got two things going on there the speed of light as it smashes into your retina and the speed of electrons that race by the switch heading for the light's filament. Those little boogers are fast. You could climb into your refrigerator to check and see if the light really goes off but be sure and tell someone you're going in there so they'll know where to find your body when you don't show up for work.

Coug if you need any more help I suggest you find some old copies of "Ask Mr. Wizard!" He was Bill Nye the science guy in the fifties and sixties. It's old technology but you gotta start somewhere.
