This document discusses the idea of using sound and music to represent cosmological models and theories. It suggests that mathematics can be used to describe the "utterance" or expression of physics, and that algorithms can render mathematics into sound. The document speculates that an "acoustic cosmology" could be created to reveal the utterance of a cosmological model through a musical composition generated from numerical data. It provides examples of how radio spectral cube data from astronomy has been transformed into audible sound waves to explore cosmic structures.

11. On technocracy
“I believe that in approaching our subject with the sensibilities of statisticians
and dissectionists, we distance ourselves increasingly from the marvelous
and spell-binding planet of imagination whose gravity drew us to our studies
in the first place.
A scientific understanding of the beautifully synchronized and articulated
motion.... does not impede a poetic appreciation of the same phenomenon.
Rather, the two enhance each other, a more lyrical eye lending the cold data
a romance from which is has long been divorced.”
[Watchmen, Alan Moore & Dave Gibbons]
From Pythagoras, to Kepler, to Einstein, there has been a persistent desire
to find lyrical connections that join the disciplines,
part of our search for romance, part our search for Truth.

12. Acousmatic:
sound one hears without seeing
its originating cause
(Pythagorean disciples listened to his lectures
from behind a curtain, unable to see him)
“... the art of mental representations
triggered by sound”
Homont [1996]
“the sound world is not a space
into which we can enter;
it is a world we treat at a distance”
Goehr [1999]

14. Cosmology Conjecture
Dealing with the origin, structure In the non-verbal languages of music
and space-time of the universe. and cosmology, mathematics can be
treated as a representation of the
utterance of the physics...
Utterance
Utterances do not exist in written Mathematics describes cosmological
language, only their representations do. models and, revealed by algorithms,
rendered in code, can be interpreted
into sound...
Can we create an architecture,
a soundscape, a palette, and a music,
which reveal the utterance of a
cosmological model?

15. Music of the spheres
a music thought of
not as an audible sound,
but as a mathematical transform
- a cry for a lyrical unknown?

20. The “data cube” is like an image,
but instead of each pixel being
a single “colour" it is actually a
radio spectrum.
Each pixel/spectra has been
transformed into a visible colour
so you can see it, based on its
redshift or blueshift.
Take a Radio Spectral Cube
and turn it into sound Selecting a pixel with the mouse
takes that spectrum and transforms
the radio frequencies (light) into an
audible range (sound) with an
equivalent distribution.
You can listen to, and explore,
the structure of the spiral arms.
