Last month the European Space Agency unveiled the mindblowing data collected from their Planck space telescope, which combined to form the most detailed map ever created of the cosmic microwave background — the relic radiation from the Big Bang. The map revealed the existence of features that challenge the foundations of our current understanding of the Universe. The image, which you can see below, is based on the initial 15.5 months of data from Planck and is the mission’s first all-sky picture of the oldest light in our Universe, imprinted on the sky when it was just 380,000 years old. John G. Cramer, a professor emeritus at the University of Washington, Seattle, took the impressive new data and ran them through Mathematica software to convert the CMB measurements into an audio simulation of the universe’s first 760,000 years (an extremely brief period on a cosmological scale). The result is the very first audio simulation of the bass-filled sound of the Big Bang which you can listen to below.
