Based on the UVS model, the planetary rings of a gaseous planet are formed as a result of the polar vortex pair of its outer nested atmospheric layers, have had opened to the extent that they had touched and flattened around the equatorial plane.
Note: Despite the planetary rings of Saturn have been observed 400 years ago, the causality for planetary rings is still a mystery in astronomy and astrophysics.
In the UVS worldview, the nested planetary vortical hypersphere intrinsically impels the nested polar vortex pair on the atmosphere of a planet, and thus formed its bipolar nested planetary rings and cloud bands.
From the UVS perspective, the nested polar vortex pair from the two poles of the planet have had compressed several layers of the outer nested atmosphere into a thin disk as nested flat rings; the vortical effect of the nested polar vortex pair renders the phenomenon of planetary rings.

This animation illustrates the top view from a pole of the planet with an opening vortex eye, which has eventually touched the equator plane of its grey color planet. It first illustrates how a planetary ring is being formed by its atmospheric polar vortex pair at a polar region, and then shows the planetary ring by tilting the planet to its side view.
The cognitive paradox that renders the planetary rings as mysterious phenomena, was thus resolved with its underlying vortical structure and mechanism illustrated.

In the Solar System, other than the planetary rings of Saturn could be observed, such mysterious phenomena have also been observed on Jupiter, Uranus, and Neptune.
Heuristically, an optically invisible flattened atmospheric layer that segregates two optically visible atmospheric layers, would be optically rendered as a void region that segregates its two adjacent planetary rings. It could also segregate a planetary ring to make it appears as if it was formed apart from the surface of the planet around its equator.
“By visualizing the underlying vortical structures and mechanisms, it intuitively reveals the actualities of the mysteriously rendered natural phenomena.” - UVS inspired
