Baryon Acoustic Oscillations
Sound waves in the primordial plasma that left characteristic distance scales, used as a “standard ruler.” The Role of Primordial Sound Waves In the early universe (before recombination at ~380,000 years...

Cosmic Inflation: Theory and Evidence
Explains the horizon and flatness problems, leaving imprints in the CMB The Conundrums of the Early Universe In the standard Big Bang model before inflation’s proposal, the universe expanded from...
