Actually the mass of light is said to be infinite and as a body approaches the speed of light its mass will increase infinitely. As energy, light has mass that is also affected by gravity.
Dark is dark because the lights are out. Until a space becomes illuminated by light, it is darkness. Light can be measured. Darkness cannot. Darkness is not a thing, nor a wave, nor anything. You cannot measure darkness. Darkness is the absence of light.
Stating that darkness is something such as light's opposite is like saying atheism is a religion opposite of the belief in God. Atheism is merely the disacknowledgement and neglect of the belief in God. It is not a dogma. Darkness is nonvisible and does not exist unto itself.

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."

Darkness is the absence of light. Hence if light has weight then darkness has no weight. Conversely, if light has no weight then by definition, darkness must have weight. I guess you will have to weight and see.

We know that there is dark, because there is light. If there was no light, then we would have no concept of dark either. Since we think that space is dark, and that we are in it, it is difficult to imagine what space itself is in. So if we were outside it, may be we could measure dark.

Light does have weight. Where did you get your information?

Photon has weight.
Darkness is the absence of light, therefore no weight.
Pretty consistent.
