What realization does the dark night sky provide as strong evidence for?
Answer
That the universe is evolving and had a beginning, confirming the Big Bang model over an infinite, unchanging background.
The persistence of darkness in the night sky serves as critical empirical evidence supporting the modern cosmological model. If the universe were static and infinitely old, it would be bright. Because the sky is dark, it confirms that the cosmos has a finite history; light from the most distant regions has not yet reached us because the universe began expanding from a singularity only 13.8 billion years ago. This dynamic, evolving state is the cornerstone of the Big Bang theory.
