- Some objects may appear dark, but they may be bright at a frequency that the human eye cannot perceive in some instances.
- Exposure to alternating night and day has caused many evolutionary changes.
- In the darkness, there are no light sources, making things hard to see.
- When a vertebrate enters a dark room, its pupils dilate (like a camera adjusting its focus) and allow light to enter the eye and improve vision.
- Also, the light-detecting cells in the human eye regenerate more rhodopsin when adapting to darkness.
- People may think that darkness is against a white background. It is not. It is always whiteness is against a dark background.
- One scientific measure of darkness is the Dark-Sky Bortle Scale that indicates stars’ brightness and the observability of celestial objects at that location.
- It is light dispelling darkness, and darkness in a heavenly body is considered a black hole.
- Darkness is considered natural for the universe, while brightness is natural for Existence, but existence includes blackness is the irony!
