Final answer:

Penzias and Wilson discovered the original heat from the Big Bang, known as the cosmic microwave background, leading to a Nobel Prize in Physics.


Explanation:

The radiation detected by Arno Penzias and Robert Wilson was actually the original heat from the Big Bang. This discovery matched the predictions of the Big Bang theory and provided strong evidence for its validity.

They observed the cosmic microwave background (CMB), which is the afterglow of the Big Bang, confirming the hot and dense early universe.

This discovery led to the Nobel Prize in Physics in 1978 for Penzias and Wilson, highlighting the significance of their accidental but groundbreaking finding.
