The Cosmic Microwave Background (CMB) is a cornerstone of modern cosmology, providing a snapshot of the universe when it was just 380,000 years old. This ancient light offers a wealth of information about the early universe, its composition, and the fundamental parameters of the Big Bang model. In this article, we explore the significance of the CMB, the key discoveries made through its study, and the ongoing research that continues to refine our understanding of cosmology.
In 1905, sitting in a Swiss Patent office a young patent clerk Albert Einstein unrooted the orthodox thinking of the Physicists who had till then believed that light was a form of electromagnetic radiation. Einstein challenged this assumption, proposing that light was not a continuous wave of energy but consisted of tiny particles or corpuscles.
It might sound odd to anybody who is not from a scientific background that we only know just about less than 5% of the universe. So our understanding of the known universe is minuscule in comparison to what we don’t know. It is estimated that 28% of the universe is dark matter while a whooping 67% is dark energy. But now the question is what are these dark matter or dark energy?
