Black Holes and the Sonic Song of the Universe

by Trent Gilliss, senior editor

As Gordon Hempton points out, silence isn’t necessarily an absence of sound but a presence all its own. And, in much the same way, physicist Janna Levin says, space isn’t necessarily quiet either. Working at her lab at Columbia University, she projects that the universe creates an aural footprint that “will be music to our ears because it will be the quiet echo of that moment of our creation of our observable universe.” If we can only pick it up…

In this presentation at TED 2011, she plays her projections of the sounds the universe makes — black holes merging and falling into one another, the “white noise of the Big Bang. It’ll make you wonder about the biggest questions at the core of what it means to be a sentient being in this universe or the next.
