“With the right ears even a lesser creature can hear the song. It is sung constantly, from the heart of each atom and star. The galaxies hum of shape and form in their essence. That is their secret. The particles whisper of the nature of proper interactions. That is their game. And during a storm, in the forest, on the right night, it is no secret that the leaves all sing of God.”
― Exurb1a, The Fifth Science

“The true horror of existence is not the certainty of death, nor the threat of hell, but the knowledge that we will likely go our entire lives as impossibly complex machines, walking about in an impossibly complex universe, and never truly discover what it was all for. I don’t know is brave. I’ll never know is heroic.”
― Exurb1a, Geometry for Ocelots

“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened.”
― Douglas Adams, The Restaurant at the End of the Universe

“reality” (one of the few words which mean nothing without quotes)”
