The Sound The Universe Makes

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack — a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a drum.) An accessible and mind-expanding soundwalk through the universe.

Janna Levin is a professor of physics and astronomy at Barnard, where she studies the early universe, chaos, and black holes. She’s the author of “How the Universe Got Its Spots” and the novel “A Madman Dreams of Turing Machines.”

This TED talk is especially pertinent to the project that I am working on as it answers the fundamental problem with my project in that there is no sound in Space. Prof. Janna Levin focuses on the sounds that black-holes make as they shape the universe and gravity around them and she also discusses how we might go about figuring out what the sound of the big bang would be.

I have to admit that the sounds that are played during the talk are not at all what I expected. To me they sound like a very basic synthesiser with one oscillator which is being effected by a LFO which is increasing in speed. As these black-hole rotate and orbit each other and flay waves of gravity around, these are the sounds that would be generated. A very interesting talk and also very inspirational.
