A Cosmological Horizon Without a Wall
A conceptual visualization of a cosmological horizon, where the limits of accessible information meet the mathematics of an expanding universe. The horizon is not a physical wall or the outer edge of space. Illustration: The Last Transmission.

THE OBSERVATION
What we can actually see.
Cosmological horizons describe limits on accessible information or causal communication, depending on the definition. Expansion data can be fitted with models that introduce additional terms, but a horizon is not a physical wall at the edge of all space.
THE ILLUSTRATION
What the artwork imagines.
A conceptual visualization of a cosmological horizon, where the limits of accessible information meet the mathematics of an expanding universe. The horizon is not a physical wall or the outer edge of space. Illustration: The Last Transmission. The selected artwork is a conceptual reconstruction. Viewpoint, lighting and apparent detail are illustrative, not additional measurements or a confirmed photograph of the depicted event.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
A thermodynamic extension to cosmology asks whether horizon-related entropy can help describe expansion. Mathematical fit and physical explanation must be judged separately from an appealing idea about a cosmic boundary.
