The current understanding of the shape of the universe based on observational data and theoretical models suggests that the universe is not shaped like an enormous torus (doughnut/ring). The prevailing cosmological model, known as the Lambda-CDM model, describes the universe as flat on large scales.
In this model, the universe is thought to be infinite and unbounded, without any detectable curvature. Galaxies are distributed throughout the universe, and there is no evidence to suggest that they would be confined to a specific structure like an inner ring of a torus.
However, it's important to note that our understanding of the universe is continuously evolving as new observations and data become available. The possibility of a torus-shaped universe or other exotic topologies cannot be definitively ruled out, although they are currently considered less likely based on the available evidence. Scientific research and future observations may provide further insights into the true nature of the universe's shape.
