Red when the cell holds oxygen, blue when its malnurisued from the lack of oxygen and black anywere else in the body, that cant be seen. We see color when light rays reflect off an object. If you put a red tomato in the refrigorator, and shut the door, the tomato is no longer red, it is black. If E=MCsquared, if we isolate light we get energy divided by mass to make light. So if i make a object that turns light into energy it will be invisible, because it wouldnt reflect the rays, it would absorb them. Right? If all mass had gravity, and all mass is composed of atoms, then gravity must be caused by atoms. Right?. Maybe its the strong force that the nucleus has that holds the atoms togeater. Though that bonding force is weak individuly, multiplied a trillions times we get gravity? Sound is the movement of molecules, pushed into our ears, if a tree falls in the woods, and no one is around, will it make a sound or will it just pushed the molecules.
