There is, in fact, a spot in a cockroach’s cluster of nerve cells (they don’t technically have brains) that can be poked to move its legs. His solution: to hijack the nervous systems of cockroaches to move around, using his tongue on a roach’s brain to control its legs. The recent release of a “Pickle Rick” flavour of Pringles is a nod to one of the show’s cult episodes, where Rick turns himself into a pickle to get out of family therapy – only to find himself trapped in his new form. Science aside, wormholes could be feasible, but would require approximately 10 9 billion electron volts of energy. Being the universe’s most intelligent being, it makes sense that Rick has found a way to create this technology. This would require three things in reality, writes Brady: an energy source, a means to find the right destination and, most importantly, a way to traverse wormholes. Perhaps Rick’s most treasured tool, his portal gun allows him to open wormholes to almost every conceivable location in the multiverse. Either way, because the universe keeps expanding, we probably won’t ever be able to travel to any of these universes to find out. Based on predictions of accepted theories – namely cosmic inflation (the stretching of the universe) and quantum field theory – there are two main ways to view how the multiverse might work: it could be like an infinite “patchwork quilt” of universes, or they could be in “bubbles” separated by empty space due to eternal inflation.

It is still impossible to test or observe potential multiverses, but some physicists aren’t ruling it out. The world that Rick and Morty inhabit exists as part of the multiverse – a collection of different universes – offering infinite possibilities for the duo’s adventures. But how realistic are the show’s scientific ideas really, and how accurately are they portrayed? Author Matt Brady foresaw the need to understand the facts behind the programme, and with the help of his book The Science of Rick and Morty: An unofficial guide, we can examine some of the show’s key scientific themes.

Part of Rick and Morty’s appeal is its exaggerated use of obscure scientific concepts and futuristic technology that always seem to have a tinge of truth. Rick and Morty, the animated science-fiction sitcom featuring the adventures of genius scientist Rick Sanchez and his hapless grandson Morty Smith has returned for a fourth season.
