Depends on the time of year. Longest period of darkness falls on a day in December, Winter Solstice, this year on December 21.

might be a question of where one chooses to put their focus, i mean life is better right now by any measure you might care to name than it was at virtually any time in history?

There definitely needs to be more Darkness in this world…

The color black does not exist. It is not a light wave. Somehings can absorb light leaving an apparence of darkness to our brain.

The entire rainbow of radiation observable to the human eye only makes up a tiny portion of the electromagnetic spectrum – about 0.0035 percent. This range of wavelengths is known as visible light. [energy.gov]

depends on where you try to read the small print.

Technically there is no such thing as darkness, just light levels lower than the human eye can detect.
We only think there is darkness because we are insensitive, even inside a sealed can some waves of electro-magnetic radiation get through.

Just as there is no absolute zero, so no cold , only too low a level of heat for us to survive in.
