The Big Bang Theory And The Birth Of Cosmic Microwave Background Radiation
The Big Bang Theory proposes that the universe began as a singular point and expanded rapidly, giving rise to all matter and energy in the cosmos. As the universe expanded and cooled down, photons no longer interacted with charged particles, marking the era of recombination. This event, occurring about 380,000 years after the Big Bang, allowed photons to travel freely, forming the Cosmic Microwave Background Radiation (CMB).
CMB is essentially the residual thermal energy left from the hot, dense early universe. These photons have since cooled down to microwave wavelengths, filling the universe in all directions. Discovered in 1965 by Arno Penzias and Robert Wilson, CMB provides crucial evidence supporting the Big Bang Theory and offers a unique window into the early universe. By studying the CMB, scientists can unravel the mysteries of cosmic evolution, such as the formation of galaxies, stars, and large-scale structures in the universe.
In essence, the existence of the Cosmic Microwave Background Radiation serves as a powerful confirmation of the Big Bang Theory’s predictions, shedding light on the universe’s early stages and providing key insights into its formation and evolution.
