"Godel's rotating universe", also called "Godel's Universe",
is a solution that godel found in 1949 to the Einstein Field Equations
In this universe, the metric is unphysical, because there exist something called closed timelike curves.
If you enter in some of these timelike curves, you can return to the past.

I would not call that 'rotating' but merely a circular or closed time loop instead.
Rotating seems to mean that the universe itself rotates around some fix axis, which is probably not what is being meant.

I think it meant rptating space.

IF YOU CAN TRAVEL IN THIS UNIVERSE BACK IN TIME CAN YOU SEE YOURSELF IN THE PAST ?
Does anyone know what is the Compass of the Inertia ? It is in the Godel's article .

Many Thanks
