Sound Of The Beginning Of The Universe

This recording of the sound of the Big Bang was created by physicist John G. Cramer from the University of Washington. His Mathematica program (or notebook) combines the WMAP measured frequencies, appropriately scaled for the human ear, assuming that all the sinusoids start at a maximum at t=0 (the start of the Big Bang), and frequency-shifts them downward as time 2/3 as the universe expands and becomes more of a "bass instrument". The simulation lasts 100 seconds representing the first 760 thousand years of evolution of the universe and varies the sound intensity to match the cosmic microwave which, according to WMAP, peaked at 379 thousand years and dropped to 60% intensity in 110 thousand years before and after the peak time. The sound frequencies used in the simulation must be boosted upward by a huge factor (about 10 to the 26 power) to match the response of the human ear, because the actual Big Bang frequencies, which had wavelengths on the order of a fraction of the size of the universe, were far too low to be heard by humans (even had any been around).

A moment of appreciation for the camera man who travelled through time to record this

A moment of appreciation for the uploader for replying to all the comments with so much patience....!!!

This is mind blowing! This should have millions of views

É COMO SE ALGUÉM ESTIVESSE MANIPULANDO, & CONTROLADO O SOM.
NÃO PERDE O RITMO, NEM A MELODIA, PERFEITO!

[daryayousefzadeh]

It's kinda scary, but really makes you wonder how and why we're here..

[brettbrannon]

That’s the sound I use to goto sleep to when I was a little kid waiting for FRIDAY NIGHT VIDEOS to come on😜😜😜

For a moment I thought the Doctor Who theme was about to begin, complete with Peter Davison's big face, lol.

Maybe one day we can see what that area in space look like with the New Webb space telescope. Let's go....

How do we know that this is the sound of the beginning of the universe?
Just curious to know

[ericplays]

I think how he got this was using a radio wave repeater at the frequency of what the universe broadcasted when it was forming (becuase many things in the early universe broadcasted radio waves) and converted it to audio to get this.

UNIVERSO = PURAMENTE & SOMENTE ELETRÔNICA.
O SOM É A PROVA!

[timothymcgervey]

It'd be lovely to have this somehow converted into an ultrasound.

[mrksvw]

Anyone know what he used to make the sound? A type of synth?

UMA MELODIA PADRONIZADA, CONTROLADA, COM UM RITMO.
COM UM RITMO SINCRONIZADO.

It gets soo weird when i think about life and why we exist as a planet. Why do we even exist ? Just to die one day ? Nah man. I can't be the only one who thinks that we are being studied as a species and death is not what we think it is. Are Human A.I ?

[clipix]

How they recorded 🤔?
Turning CMB waves to sound!?
Just curious to know

[brucecopney]

How do you know that the sound of the big bang...I need more research.

[mohdsalafudinjiee]

i hear whoop when the sound is slowing down

[guilhermecordeirorodrigues]

"O SINTETIZADOR CÓSMICO" DA YAMAHA.

[chiknsld]

dark matter is like wtf? ...I don't sound like this at all :/
