"Infinity Environment," an art piece by Doug Wheeler on display at the David Zwirner Gallery in New York, conveys a sense of infinite space.

Islamic art often makes use of repeated elements, such as geometrical floral or vegetal designs. Known as arabesques, these patterns symbolize the transcendent, indivisible and infinite nature of God. One theory, though it is disputed, holds that artists intentionally introduced mistakes in arabesques as a show of humility; the idea is that only God can produce perfection.

## bubble universes

This artist's impression is a visualization of the multiverse, a hypothetical, infinitely large expanse that (if it exists) contains infinitely many bubble universes, one of which is our own. Quantum fluctuations at the moment that each bubble universe inflated cause each one to take on different values of the fundamental constants. Thus they have wildly different properties.

One of the oldest conceptions of infinity, originating in Egypt, couched it as a serpent or dragon eating its own tail. The creature, named Ouroboros, symbolized the cyclic nature of life, and the notion that this cycle continues forever. One theory holds that the modern-day infinity symbol, a sideways figure eight, is derived from Ouroboros.
This (public domain) image shows a drawing of Ouroboros by Theodoros Pelecanos, in his alchemical tract titled Synosius (1478).

This famous Ouroboros drawing appeared in an early alchemical text called "The Chrysopoeia of Cleopatra," dating to 2nd century in Alexandria, Egypt. The serpent Ouroboros encloses the words "hen to pan," meaning "one is the all." The black and white halves of the serpent represent the duality of existence.

This is a partial view of the Mandelbrot set an infinitely complex two-dimensional structure that represents the solution to an equation. When you zoom in on the edge of the structure, it never ceases to appear complicated. This is the case because the Mandelbrot set doesn't have a finite edge, but rather an infinitely twisting and turning one. The edge of the structure is also "self-similar," meaning that the same shapes and patterns appear at every level of magnification.
