About Mark Whittle

Biography and Academic Role

Mark Whittle is a Professor of Astronomy at the University of Virginia, based in the Department of Astronomy Building.[10] He teaches advanced courses such as Extragalactic Astronomy (ASTR 5630), held Tuesdays and Thursdays from 2:00-3:15pm in 2014.[2] Contact: dmw8f@virginia.edu, office 216 Astronomy Building.[10]

Big Bang Acoustics: Core Concept

Whittle's signature work explores 'Big Bang Acoustics' – the sounds of the early universe, despite the 'Big Bang' title suggesting an explosion without sound.[1] He describes a 'symphony' of three movements: plasma oscillations before recombination, baryon acoustic oscillations, and their imprint on the CMB.[7][9] This framework reveals how sound waves shaped the universe's structure.[5]

Sounds from the Infant Universe

Whittle converts CMB power spectrum data into audible tones, highlighting the 'sound spectrum' with fundamentals and harmonics, akin to a vibrating object.[5] Key pieces include PDFs on 'big bang acoustics' and 'primordial sounds,' presented at AAS meetings.[1][4][8] His site features 'Sounds From The Newborn Universe,' explaining primordial sound evidence.[9]

Visualizations of Cosmic Dynamics

Whittle's Big Bang Acoustics website includes images depicting 'Growth of Atomic and Dark Matter Roughness'[3] and 'Gas Bounces In and Out of Gravitational Valleys,' illustrating acoustic oscillations and matter perturbations.[6] These visuals support the narrative of early universe 'roughness' evolution.[3]

Public Outreach and Presentations

He delivered talks like 'Sounds from the Infant Universe' at AAS sessions, emphasizing CMB measurements' impressiveness.[4] A 2004 AAS press release promotes 'primordial sounds,' linking to his site.[8] Resources like echoes.pdf make cosmology accessible.[1]
