Want to know how The big bang sounded

 My head hurts when I think about the 

Big bang_the moment when The 

Universe . started how did something

Come out of nothing? is There a

Beginning ot Time? is There a

Multiverse? I recall a conversation I

Had with Cambridge university 

Professor on the topic. He wasn't able 

To answer all My Question. At least

Not in way that was satisfying to me

But he did show me what The big bang sounded like
