Three “deep” questions you may wish to ponder yourself on, what are these and maybe what is the relationship?
For me, something dark always conjures up the sinister. Just like Pink Floyds ‘Dark side of the moon’, though great music but your imagination can conjure Earth being under threat! (But what is on the dark aspect of the planet?)
When one thinks about astronomy, and you look at the sky at night, the word ‘infinity’ immediately comes to mind as it’s never ending. The infinity perspective could be relevant to the ‘dark web‘!!
In the ‘Art’ arena ‘The hunt in the forest‘ by Italian artist Paolo Uccello depicts the hunt disappearing into the darkforest.
Or conversely, when considering World War 2 in Europe, engulfed with Nazism. The dark epitome of Hitler’s ‘Mein Kampf’, where he depicts his ideology for Germany.
