The Quantum Junction Decal shows a traffic sign, the speed of light plus instructions to get in both lanes. It’s a nod to the behaviour of light in the double-slit experiment, in which a light particle, aka photon, is shot at two slits. Instead of passing through one of the two slits, it’s possible – under certain circumstances – for the photon to pass through both slits at the same time! If we circle back to our traffic sign, this would mean that a car would have to merge into both lanes at the same time. Somewhat dangerous, though, fortunately for us, virtually impossible ;).
