What are the most widely accepted geometries of the universe?

The concept of "Geometries of the Universe" refers to the different ways in which the universe can be described and understood through mathematical and geometric models. These models help us understand the shape, size, and structure of the universe at various scales.
The three main types of geometries used to describe the universe are Euclidean, Hyperbolic, and Elliptic. Euclidean geometry is based on the principles of Euclid and describes a flat or "flat-like" universe. Hyperbolic geometry describes a negatively curved universe, while Elliptic geometry describes a positively curved universe.
Scientists determine the geometry of the universe through various methods, such as making precise measurements of cosmic microwave background radiation, analyzing the distribution of galaxies, and studying the behavior of light and other electromagnetic radiation in space. These methods help us understand the overall shape and structure of the universe.
The geometry of the universe can tell us a lot about its fate. For example, a flat universe suggests that it will continue expanding forever, while a positively curved universe suggests that it will eventually collapse in on itself. The geometry of the universe also plays a role in the formation and evolution of galaxies, stars, and other celestial bodies.
The geometry of the universe is not a fixed concept and can change over time. For instance, the shape of the universe can change due to the expansion or contraction of space, the presence of dark matter and dark energy, and other cosmic forces. As our understanding of the universe evolves, so too may our understanding of its geometry.
