Models of the Universe

Models of the universe are scientific ideas about its overall structure and origin. The Big Bang model suggests the universe began from a hot, dense point around 13.8 billion years ago and has been expanding ever since. Some models include a “multi-universe,” proposing our universe might be one of many. Others explore whether the universe is finite or infinite, flat or curved. These models help scientists understand cosmic evolution, the nature of dark matter and dark energy, and the universe’s ultimate fate. While details vary, all aim to describe the universe’s origin, structure, and future based on observable evidence and physical laws.
