In simplest terms, the rate at which the universe expands on paper doesn’t match actual astronomical observations. The most widely accepted theoretical model, the Lambda/Cold Dark Matter model (ΛCDM), says the universe is growing at 67-68 km/s/Mpc. Szapudi and their colleagues’ new model indicates the universe finishes a single rotation once every 500 billion years—meaning there’s still quite a bit of time before the universe completes its first full circuit. Looking ahead, astronomers hope to construct a full computer model of the universe based in part of their new theory. From there, they will hopefully be able to pinpoint signs of cosmic spinning to search for among the stars.
