Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.

The Grutas de Cacahuamilpa National Park in Guerrero, Mexico, is best known for the Grutas de Cacahuamilpa Caverns, which are one of the largest cave systems in the world.

A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter.
