Origins Of Cosmic Microwave Radiation
The origins of cosmic microwave radiation trace back to the early universe, specifically to about 380,000 years after the Big Bang. During this epoch, protons and electrons combined to form neutral hydrogen atoms, allowing photons to travel freely through space. This period, known as recombination, marked a pivotal moment when the universe transitioned from an opaque plasma to a transparent state. The photons present at that time now constitute the cosmic microwave background radiation that we observe today.
The relic radiation captured in cosmic microwave background (CMB) maps offers a snapshot of the universe’s early conditions, revealing temperature fluctuations on a minuscule scale. These fluctuations shed light on the distribution of matter in the primordial universe and the seeds that eventually led to the formation of cosmic structures like galaxies and galaxy clusters. By studying the origins of cosmic microwave radiation, scientists gain valuable insights into the fundamental properties of the universe and its evolution over billions of years.
