TL;DR

This paper proposes a conceptual and artistic synthesis of modern cosmology through the sculpture 'An End to Modernity,' using spatial dimensions to represent cosmic time, thereby visualizing the universe's 14-billion-year evolution from the Big Bang to the present. By mapping galaxy formation, dark matter, quasars, and the cosmic microwave background onto a radial structure, the work encodes key observational cosmology principles in an intuitive, aesthetic form.

ABSTRACT

Since 2004, I have been collaborating with artist Josiah McElheny on the design of cosmological sculptures, inspired originally by the chandeliers of the Metropolitan Opera House in New York. This article describes the science behind the four works that have emerged from this collaboration to date: An End to Modernity (2005), The Last Scattering Surface (2006), The End of the Dark Ages (2008), and Island Universe (2008). These works incorporate idealized representations of many fundamental aspects of contemporary cosmology, including expansion of the universe, the last scattering surface, cosmic microwave background anisotropies, the growth and morphological transformation of galaxies, the rise and fall of the quasar population, the development of large scale structure, and the possibility that our universe is one of many cosmic islands in an eternally inflating multiverse. A companion article describes the history of the collaboration.

Motivation & Objective

• To create a visual and spatial representation of cosmic evolution that accurately reflects modern cosmological observations despite the inherent difficulty of depicting the Big Bang as a non-explosive, spacetime-origin event.
• To resolve the artistic challenge of depicting a universe with no center or edge by reinterpreting spatial distance as a proxy for cosmic time.
• To encode empirical cosmological features—such as the last scattering surface, galaxy clustering, and quasar evolution—into a sculptural form using physical parameters like rod length, cluster size, and lamp brightness.
• To explore the philosophical and scientific implications of eternal inflation and multiverse theory through a series of five sculptures ('Island Universe'), each representing a distinct cosmological outcome based on varying inflationary conditions.
• To bridge the gap between abstract cosmological theory and public understanding by embedding observational data into an immersive, aesthetic experience accessible through art and spatial intuition.

Proposed method

• Using a radial sculpture with 230 rods extending from a central aluminum sphere, each rod's length maps to a specific cosmic epoch, with distance from the center representing the passage of time from the Big Bang to the present.
• Assigning physical properties to each rod's endpoint (e.g., cluster size, glass disk count, lamp brightness) based on cosmological models: galaxy formation at 100 million years, quasar luminosity peaking at 2–4 billion years, and elliptical galaxies forming via collisions.
• Representing the last scattering surface via a central opaque aluminum sphere, which hides the initial singularity and symbolizes the moment the universe became transparent, analogous to the cosmic microwave background.
• Encoding dark matter’s gravitational influence through the spatial arrangement and clustering of glass elements, even though dark matter itself is invisible, reflecting its role in structure formation.
• Applying a logarithmic scale where every 7.2 inches of radial distance corresponds to a doubling of cosmic size, compressing the 1000-fold expansion of the universe into a 6-foot sculpture.
• Extending the conceptual framework to five additional sculptures ('Island Universe') that model alternative cosmologies based on different inflationary outcomes, such as high or low power spectra, anisotropy, or early dark energy dominance.

Experimental results

Research questions

• RQ1 How can the abstract, non-intuitive nature of the Big Bang—where space and time themselves originate—be represented in a static, spatial artwork?
• RQ2 In what ways can the radial dimension of a sculpture be used to encode the passage of cosmic time, given that time is not a spatial dimension in classical physics?
• RQ3 How can observational cosmological phenomena—such as galaxy formation, quasar evolution, and the cosmic microwave background—be encoded in physical parameters of a sculpture (e.g., rod length, cluster size, lamp brightness)?
• RQ4 What insights emerge when alternative cosmological models (e.g., high- or low-power inflation, dark energy dominance, anisotropic structure) are visualized as distinct sculptural forms?
• RQ5 How does the absence of a privileged observer in eternal inflation affect the possibility of a unified temporal narrative across multiple universes, and how is this reflected in the artwork’s spatial structure?

Key findings

• The sculpture 'An End to Modernity' successfully maps the 14-billion-year history of cosmic expansion by using radial distance as a proxy for time, with each rod’s length corresponding to a specific epoch in cosmic evolution.
• Galaxy formation begins at 100 million years after the Big Bang, represented by disk-shaped clusters of glass disks three feet from the center, consistent with observations of early rotating gas clouds.
• The peak of quasar activity occurs between 2 and 4 billion years after the Big Bang, encoded in the highest concentration and brightness of lamps, reflecting the growth of supermassive black holes from accreted gas.
• Elliptical galaxies, formed by violent collisions of disk galaxies, are represented by glass spheres and are most prevalent in dense clusters, appearing on longer rods toward the outer edge of the sculpture.
• The central aluminum sphere represents the last scattering surface, hiding the Big Bang singularity and symbolizing the moment the universe became transparent, with the cosmic microwave background as its remnant.
• The 'Island Universe' series demonstrates that varying inflationary parameters—such as power spectrum amplitude, anisotropy, or dark energy onset—produce distinct large-scale structures, including uniformly smooth universes, highly clustered systems, or isolated, slowly evolving galaxies.
