The sound the universe makes - Janna Levin

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.

Talk by Janna Levin.

The soundtrack of the universe will differ depending on auditory capacity. We (humans) only ‘hear’ a limited portion of waves that are out there. Which begs the question - is there an organism that can ‘hear’ light? ‘See’ sound? Is what we hear what some other organism sees? We have to remember that our observations are NOT correct - they are limited by our capacity. It’s all relative. To coin a phrase.

f we can listen to black holes one day that are thousands of light years away than I have no doubt that one day we will listen in on alien jungles.

11:07 It kind of sounds like Euler's disk.

i envy religious people sometimes...theyre going to their graves with the certainty that all the mysteries of the universe will be revealed to them....but then again...it would just be some unimaginative bs like "god did it" so, whats the point...

I laughed hard, I don't know why but I did...

a black hole sounds like a helicopter.
