‘Pixels’, An Infinitely Regressing Comic Celebrating Randall Munroe’s ‘What If?’ Book Launch

“Pixels” by xkcd is a comic celebrating the release of the book What If?: Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe, creator of xkcd. The comic is at least partly an homage to the “turtles all the way down” expression about infinite regress.
