explain why a certain type of radiation led to the acceptance of the Big Bang theory. Decades, after the red ship of galaxies was first discovered write three sentences.

The discovery of cosmic microwave background radiation in 1964 provided strong evidence for the Big Bang theory, as it is considered the afterglow of the universe's initial explosion. Scientists found that this radiation was consistent with the predictions of the Big Bang model, further solidifying its acceptance among the scientific community. Decades after the red shift of galaxies was first observed, the discovery of cosmic microwave background radiation provided crucial supporting evidence for the Big Bang theory, leading to its widespread acceptance as the leading explanation for the origin of the universe.
