The Total Perspective Vortex appears in The Hitchhiker’s Guide to the Galaxy. It shows one their relevance with respect to the rest of the Universe..
When you are put into the Vortex you are given just one momentary glimpse of the entire unimaginable infinity of creation, and somewhere in it there’s a tiny little speck, a microscopic dot on a microscopic dot, which says, “You are here.”
The only person to survive the Vortex interprets it as telling him that he was the most important being in the universe. It did this because of a mistake, but due to his ego, he finds the mistake perfectly logical.
I thought of this today when I was reading someone’s tweets. Because reasons.
