The concept of a doughnut-shaped universe is not a new one. Physicists propose that this concept could apply to the universe as well.
Doughnut-Shaped Universe
The doughnut-shaped universe, also known as a toroidal universe, is a hypothetical model of the universe’s large-scale structure. This model suggests that the universe may have a finite yet unbounded shape, similar to a doughnut or torus.
Implications and Observations
If the universe does have a doughnut-like shape, it would have several interesting implications. For instance, in a toroidal universe, light and other forms of radiation could theoretically travel around the universe and return to their starting point. This could potentially explain certain observed cosmic microwave background patterns that are difficult to explain in a flat or spherical universe.
Additionally, the doughnut-shaped universe model could help resolve the horizon problem, which arises in the standard cosmological model, where different regions of the universe appear to be in thermal equilibrium despite being causally disconnected.
