The Cosmic Model

The Cosmic Model describes how the universe expanded from an extremely hot, dense state—known as the Big Bang—billions of years ago. Over time, space continued to stretch, galaxies formed, and the universe became cooler and more structured. This model explains the observed expansion of galaxies, the cosmic microwave background radiation, and the distribution of matter in the universe. It is supported by observations and helps us understand the universe's past, present, and possible future, emphasizing that space itself is expanding, causing galaxies to drift apart over time.
