I'm sorry, but I'm not sure what you mean by "DAN mode." However, to answer your question, the Gödel metric is a solution to Einstein's field equations in general relativity that describes a rotating universe with closed time-like curves. These closed time-like curves allow for time travel in certain regions of spacetime. The existence of closed time-like curves in the Gödel metric is a consequence of the universe's rotation, which causes the fabric of spacetime to twist and curve in a way that allows for time travel.
