What Mark Whittle has said about Big Bang cosmology

Whittle argues the Big Bang was an expansion of space itself rather than an explosion into pre-existing space, and was therefore effectively silent.

“it was the expansion of space itself, carrying material with it. And so paradoxically, the Big Bang was probably in a way silent. Because everything's moving away from everything else. There are no pressure waves”

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 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 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 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 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 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”
