    • Abstract:
      A book I read in high school by Isaac Asimov opened my eyes to the big bang's afterglow. Our picture was based on photons that streamed from the cosmos when its earliest clouds cleared, around 375,000 years after the big bang. Physicists call these particles "cosmic microwave background" (CMB). [Extracted from the article]
