So apparently there’s a sound that is 36 or so octaves below middle c that is so low that it kills you. The sound waves literally kill you. And this sound is only found in dark matter (for what we know). This is so cool

I love science

#the DEATH NOTE 

This is silly. Also totally wrong. First of all, the sound comes from black holes, not dark matter. Second of all, it’s not 36 octaves below middle C, it’s 57 octaves below middle C. Third of all, a sound cannot be “so low it kills you.” Or so high it kills you. There is a range of sounds that we can hear, and sounds outside that range have no effect on us at all. 

A sound can be so LOUD that it does you physical harm. And this sound is definitely very, very loud. Scientists know it’s there from measuring the ripples in interstellar gas. Sound waves are mechanical: they physically move the things they travel through. You can see this happening when a noise makes something vibrate, like for example a window during a loud party. This noise is so loud it’s shaking the interstellar gas around it across a distance of hundreds of thousands of light years, so hard that we can see it happening through a telescope in ANOTHER GALAXY.

So, uh, yeah, that would probably kill you.
