We study the geodesic motion in a space-time describing a swirling universe.
We show that the geodesic equations can be fully decoupled in the
analytical solutions to the geodesic equations can be given in terms of
elementary and elliptic functions. We also consider a space-time describing a
static black hole immersed in a swirling universe. In this case, full
separation of variables is not possible and the geodesic equations have to be
solved numerically.

We have studied the geodesic motion in a space-time describing a swirling universe and have made some interesting findings. Firstly, we have discovered that the geodesic equations can be fully decoupled in the Hamilton-Jacobi formalism, which allows us to obtain an additional constant of motion. This is a significant result as it provides us with a deeper understanding of the dynamics of particles moving in a swirling universe.

In addition, we have found analytical solutions to the geodesic equations, which are expressed in terms of elementary and elliptic functions. These solutions provide us with precise formulas for describing the paths of particles in this space-time.

Furthermore, we have extended our study to a space-time describing a static black hole immersed in a swirling universe. In this case, we have encountered some challenges as full separation of variables is not possible. As a result, we have had to resort to numerical methods to solve the geodesic equations. While this is a more computationally intensive approach, it allows us to obtain accurate results about the motion of particles in such a complex space-time.

Our findings pave the way for future research in this field. Below is a roadmap for readers interested in further exploring the geodesic motion in a swirling universe:
