Measuring the Universe with Baryon Acoustic Oscillations

Hidden in the large-scale structure of the Universe – the so-called cosmic web, subtle waves provide a priceless view on the cosmos, helping scientists highlight some of the mysteries about its structure, evolution, and its current accelerated expansion governed by dark energy. This phenomenon is known as Baryon Acoustic Oscillations (BAOs). To understand what they are, we must travel back in time to the early Universe! Are you ready?
