cosmic inflation theory

Cosmic inflation theory posits that shortly after the Big Bang, the universe underwent a rapid and exponential expansion, growing faster than the speed of light. This expansion smoothed out any irregularities, resulting in the uniform and isotropic universe we observe today. Inflation explains the uniformity of the cosmic microwave background radiation and the distribution of galaxies. It suggests that tiny quantum fluctuations during this brief period seeded the large-scale structure of the universe. Overall, cosmic inflation helps address several puzzles in cosmology, such as why the universe appears so homogeneous despite its vastness.
