It's a well known fact that children ask the best questions about science. For evidence of this, you need look no further than a question posed by an 11-year-old to physicist John Cramer almost a decade ago: Is there any recording of the sound of the Big Bang? The question got Cramer wondering if he could recreate an approximation of the sound of the Big Bang, so that's just what he did. Using data about the background radiation levels of the universe and translating those heat levels to sound waves, Cramer offered the first approximation of the sound that would have rung throughout the newborn universe in the millennia following the Big Bang. Now, thanks to new data from the Planck telescope, Cramer has been able to remaster the original sounds of the universe into a high-fidelity special edition, and you can take a listen below.
