universe models

Universe models describe how our universe is structured and how it evolves over time. The most widely accepted model is the Big Bang, suggesting the universe started from a hot, dense point about 13.8 billion years ago and has been expanding ever since. Other models explore different geometries — open (infinite), closed (finite but unbounded), or flat — affecting its ultimate fate. Some theories consider the universe as part of a multiverse with many universes. These models help scientists understand the universe’s origins, shape, and future by combining observations with physics theories.
