Neil deGrasse Tyson 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. In his TV appearances, puppeted by an invisible army of scriptwriters, this tendency is barely held in check, but in his lectures or 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.
