Once again you are wrong sir, darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. In fact we can use Newton's prism to break white light into many colors and study the various wavelengths of each color. You cannot measure darkness. A simple ray of light can break into a world of darkness and illuminate it. How can you know how dark a certain space is? You measure the amount of light present. Isn't this correct? Darkness is a term used by man to describe what happens when there is no light present.
Live life to the fullest. You have to color outside the lines once in a while if you want to make your life a masterpiece. Laugh some every day. Keep growing, keep dreaming, keep following your heart. The important thing is not to stop questioning.

Imagination is more important than knowledge.
Never give up on what you really want to do.
The person with big dreams is more powerful than one with all the facts.
