Inflationary Universe Model

The inflationary universe model proposes that shortly after the Big Bang, the universe underwent a rapid expansion—much faster than the speed of light. This inflationary phase, lasting only a tiny fraction of a second, caused the universe to grow exponentially, smoothing out irregularities and distributing matter evenly. It helps explain why the universe appears uniform on large scales and accounts for the formation of galaxies. This model also addresses certain puzzles in cosmology, such as the uniform temperature of the cosmic microwave background radiation, providing a clearer picture of how our universe developed to its current state.
