Randall Munroe is, supposedly, an educator and a populariser of science; it’s his job to excite people about the mysteries of the universe, communicate information, and correct popular misconceptions. This is a noble, arduous, and thankless job, which might be why he doesn’t do it. What he actually does is make the universe boring, tell people things that they already know, and dispel misconceptions that nobody actually holds. On the internet it’s torrential; a seeping flood of grey goo, paring down the world to its driest, dullest, most colourless essentials. He likes to watch scifi films, and point out all the inaccuracies. Actually, lasers wouldn’t make any sound in space; actually a light year is a unit of space rather than time; actually, none of this is real, it’s just a collection of still images projected at speed to present the illusion of movement, and all the characters are just actors who have never really been into outer space. A passionate, useless, and embarrassing defence of the blindingly obvious. In a world that’s simply given, brute fact, any attempt to imagine it into an entirely different shape must be stamped out. Why? The subject-matter is cosmic and transcendental, the object-cause is petty and stupid. Randall Munroe strides onto stage to say that actually the Earth orbits the sun, that actually living beings gain their traits through evolutionary processes, that actually your hand has five fingers, that actually cows go moo, that actually poo comes out your bum – and you are then supposed to think yes, I knew that, and imagine someone else, someone who didn’t know it already, some idiot, and think: I’m better than that person, I’m so much smarter than everyone else.
