1. Developing a Soniverse
Can sound help us understand cosmology?
Can cosmology help us understand music?
2. Musica universalis
(literally ‘universal music’)
Music of the Spheres
Harmony of the Spheres
is an ancient philosophical concept that regards
proportions in the movements of celestial bodies
3. This connection between
music, mathematics, and astronomy
had a profound impact on history,
resulting in music's inclusion in the Quadrivium:
the medieval curriculum that included
arithmetic, geometry, music, and astronomy
along with the Trivium (grammar, logic,and rhetoric)
this made up the seven liberal arts,
which are still the basis for higher education today
10. Music of the spheres
a ‘music’ thought of
not as an audible sound,
but a harmonic, mathematical
or religious concept
11. Over the last century our understanding of our universe has completely
transformed. In parallel, our ability to manipulate the microcosm of sound,
not just the macrocosm of composition, has radically changed our music.
12. Music of the hypersphere
a ‘maths’ thought of
not as a physical universe, but as an
audible, navigable sonic space
14. In the ‘data cube’ each ‘pixel’
is a whole spectrum.
Each pixel/spectra has been
transformed into a visible colour
based on its redshift or blueshift.
Selecting a pixel takes the radio
spectrum (light) and transforms
it into sound.
You can listen to, and explore,
the structure of the spiral arms.
One wavelength — ∂s
The equivalent of a photon in a sonic universe (soniverse)
nb: not to be confused with a phonon
16. Our basic soniverse has basic parameters of a ‘cosmological model’
(does include mass, density, doesn’t include particles, inﬂation, etc)
Here we create two identical ‘big bangs’ and put them at diﬀerent redshifts
(based on a randomly generated universal spectrum rest state)
Z1 and Z2 are the redshifts of the objects
H0 changes the age of the universe.
Ω = 1 would be a ﬂat soniverse, less or more changes curvature
light travel time = delay travel time
luminosity distance, = loudness/volume distance
coloured boxes are transformed into a range we can hear
Modelling a soniverse
17. The mathematics of structure, as spoken
through grains of rendered sound,
hewn from binary dust...
