What ended the ‘dark ages’ in the early universe? Webb telescope finds clue

The Hindu  

About 400,000 years after the Big Bang, the cosmos was a very dark place. However, as more and more stars formed, they produced enough light to burn away the fog by “reionising” the gas – creating the transparent universe dotted with brilliant points of light we see today. The second camp thinks we are better off ignoring the giant galaxies …
