Mark Whittle

Whittle contends science is intuitable because humans evolved amid the same physical laws and developed sensors for light and sound.

“all the laws of physics are right here on the surface of the earth and we've sort of been coached in them through our evolution”

Whittle argues that atoms from the first acoustic era now compose human brains, so the universe can witness its own origins.

“right now, some of those atoms are inside your brain, somehow witnessing and understanding their own ancestry”

Whittle proposes that subatomic quantum vibrations during inflation were amplified into sound waves that became the pattern of galaxies.

“quantum oscillations smaller than atoms get amplified by cosmic expansion to make huge sound waves that then transform into an ever-expanding tapestry of galaxies”

Whittle says Fred Hoyle coined 'Big Bang' derisively on BBC radio in the 1950s and the name stuck.

“he coined the term big bang to be slightly derisive just saying well it's nothing more than a big bang really and that name that name has stuck”

Whittle notes the primordial sound waves had frequencies of roughly one wave every 50,000 years, far below human perception.

“The frequencies of the waves that I'm talking about are one wave every 50,000 years. So, I mean, you wouldn't even live to see one wave pass you”

Whittle says the universe's acoustic era began almost immediately after the Big Bang and lasted about 400,000 years.

“started almost immediately, basically, and extended for about 400,000 years”

Whittle says the piano rendering uses the first eight harmonics, which are the ones telescopes have detected.

“those are the first eight harmonics, which are basically the eight that have been seen by telescopes”

Whittle says the raw cosmic sound resembles noise because the young universe's harmonics are very wide, so he narrowed them to make them musical.

“if you're standing at a piano, you don't put your finger on one note. You put your full forearm onto a lot of notes. It all comes out together. And so it's not very musical and it's more like noise”

Whittle chose sound rather than imagery to communicate cosmology because astronomy's public presentation is overwhelmingly visual.

“I just thought it was a wonderful way of communicating to the public what these new discoveries were, was to actually use sound as the bridge”

Whittle says wave analysis of the microwave background revealed a fundamental and harmonics, the signature of a musical instrument or human voice.

“not only were these waves basically acoustic waves, but also there was a fundamental of harmonics. And that is exactly the signature of something like a musical instrument or a human voice”

Whittle explains that light leaving the young universe at micron wavelengths was stretched by expansion into millimeter-scale microwaves.

“they started out as light, leaving the young universe with wavelengths of about a millionth of a metre. That's a micron. And they arrived a thousand times longer”
