Significance of the Observation of Cosmic Microwave Background (CMB) Radiation:
Evidence of the Big Bang Theory:
The observation of Cosmic Microwave Background (CMB) radiation is significant as it provides strong evidence in support of the Big Bang Theory. The CMB radiation is considered a remnant from the early stages of the universe when it was much hotter and denser. Its nearly uniform intensity across the sky supports the idea that the universe underwent a period of rapid expansion from a hot, dense state.
Confirmation of Predictions:
The observation of CMB radiation aligns with the predictions made by the Big Bang Theory, such as the existence of a background radiation leftover from the early universe. This confirmation strengthens the credibility of the Big Bang Theory as the most widely accepted explanation for the origin and evolution of the universe.
Insights into the Early Universe:
Studying the characteristics of CMB radiation, such as its temperature fluctuations, can provide valuable insights into the conditions of the early universe. By analyzing the patterns and variations in the CMB radiation, scientists can learn more about the composition, structure, and evolution of the universe shortly after the Big Bang.
Mapping the Universe:
Observations of CMB radiation have enabled the creation of detailed maps of the universe's large-scale structure. These maps help astronomers understand the distribution of matter and energy in the cosmos, as well as the formation of galaxies, clusters, and other cosmic structures.
Key to Cosmological Research:
CMB radiation serves as a crucial tool for cosmologists and astrophysicists to study the universe's origins, evolution, and ultimate fate. By analyzing the properties of CMB radiation, scientists can test different cosmological models and theories, leading to a deeper understanding of the universe as a whole.

- The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This 'fossil' radiation, the furthest that any telescope can see, was released soon after the 'Big Bang'. Scientists consider it as an echo or 'shockwave' of the Big Bang. Over time, this primeval light has cooled and weakened considerably; nowadays we detect it in the microwave domain.
- The CMB radiation was discovered by chance in 1965. Penzias and Wilson, two radio astronomers in the United States, registered a signal in their radio telescope that could not be attributed to any precise source in the sky. It apparently came from everywhere with the same intensity, day or night, summer or winter.
- Scientists considered their discovery as solid evidence for the 'Big Bang' theory. This theory predicted that the 'shockwave' of that primeval explosion would be still detectable as a subtle 'wallpaper' coming from everywhere behind all galaxies, quasars and galaxy clusters. Today, the Big Bang model is still the only model that is able to convincingly explain the existence of the CMB. According to this model, the Universe started with a very dense and hot phase that expanded and cooled itself; for several hundreds of thousands of years the temperature was so high that neutral atoms could not form. Hence option (b) is the correct answer.
- Today, we can detect the CMB at microwave frequencies or length scales, which are much longer than, for example, the length scales to which our eyes are can see. The CMB is the farthest and oldest light any telescope can detect. It is impossible to see further beyond the time of its release because then the Universe was completely 'opaque'. The CMB takes astronomers as close as possible to the Big Bang, and is currently one of the most promising ways we have of understanding the birth and evolution of the Universe in which we live.
