Science and the Sacred
The cosmic microwave background (CMB) is the afterglow radiation from the Big Bang, filling the universe and providing a snapshot of its early state about 380,000 years post-Big Bang. This faint, uniform radiation is crucial for understanding the universe's evolution, revealing information about its temperature, density fluctuations, and overall structure. The CMB serves as strong evidence supporting the Big Bang theory by reflecting the conditions of the universe when it first became transparent to light.
congrats on reading the definition of cosmic microwave background. now let's actually learn it.
