Infinite Universe

Topic

An infinite universe is a cosmological model in which the spatial extent of the universe is boundless and has no physical limits. Whether the universe is finite or infinite remains one of the fundamental unanswered questions in physical cosmology, closely tied to its overall shape, curvature, and topology. Current observational data, such as measurements of the cosmic microwave background, suggest that the universe is flat or nearly flat, which is consistent with an infinite spatial geometry.
