Voyager Golden Record - The Sounds of earth. September 5, 1977

It was a huge disappointment as a child to fall in love with the stars and then find out how much math it requires to get anywhere near them. 

Why is there something here, instead of nothing? And why are we aware of this question—we people, particles going around and around this black stone? Why are we aware of it?

Annie Dillard, from For the Time Being (Alfred A. Knopf, 1999)

“Clouds and currents of dark matter associated with nebular objects in the the constellation of Ophiucus.” Les énigmes de la science. 1921.
