Did you ever just feel so lucky for knowing someone you met online? Like.. I was one click away from not following you. I was one second away from never even knowing of your existence. I would never have been this happy.
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
