THERE IS DARKNESS?

Hello family of steemians, a hug, today in the challenge of celestialchallenge created by @sirknihgt I want to share the point of view of science about the DARK, there are many phrases that are attributed to the German scientist Albert Einstein, considered the most famous of the 20th century , about his perception of the dark and the supposed conversation with a Professor when he was young, I quote textually: "

And, is there darkness? The student continued.

The teacher replied: Of course.

The student answered:

Again you are wrong, sir, the darkness does not exist either. Darkness is in reality the absence of light. Light can be studied, darkness can not, there is even the Nichols prism to decompose white light into the various colors in which it is composed, with its different wavelengths. The darkness is not. A simple ray of light tears the darkness and illuminates the surface where the beam of light ends. How can you know how dark a certain space?. Based on the amount of light present in that space, is not it? Darkness is a term that man has developed to describe what happens when there is no light present.

Whether this conversation is true or not, what I want to emphasize is that scientifically the darkness does not exist because the scientific definition of light includes not only the light of the visible spectrum, but the entire electromagnetic spectrum, and a certain amount of radiation exists in each place of the universe, even if it is imperceptible to the human eye.
