Gödel's Universe

Gödel's Universe is a theoretical model proposed by mathematician Kurt Gödel, illustrating a universe filled with rotating matter that allows for unusual paths through spacetime. In this universe, the rotation creates "closed timelike curves," which are paths that loop back in time, suggesting the possibility of time travel. While mathematically consistent, Gödel's Universe is unlikely to describe our real universe, but it helps scientists explore the nature of spacetime, relativity, and the concept of time itself within Einstein's theory of general relativity.
