Have we found a new limit on the universe?kkssr/ShutterstockA newly proposed cosmic speed limit may constrain how fast anything in the universe can grow. Its existence follows from Alan Turings pioneering work on theoretical computer science, which opens the intriguing possibility that the structure of the universe is fundamentally linked to the nature of computation.Cosmic limits arent a new idea. While studying the relationship between space and time, Albert Einstein showed that nothing in the universe can exceed the speed of light, as part of his special theory of relativity. Now, Toby Ord at
