The discovery of cosmic microwave background radiation in 1965 by Arno Penzias and Robert Wilson provided strong evidence for the Big Bang theory. This faint radiation, a remnant from the early universe, has been crucial for understanding the cosmos' evolution and structure. Their discovery earned them the Nobel Prize in Physics in 1978 and remains a cornerstone of modern cosmology.

The discovery of the cosmic microwave background in 1965 provided strong evidence for the Big Bang, inspiring contemporary poetry that explores themes of origins and existence. Poets began to address the vastness of time and the echo of creation in their works.
