256x252 cm (64x84 cm each panel) | Filler on board, oak panels
My works are cast in oak panels using standard wall filler (not cement).

The stone imprints form a Voronoi pattern. Voronoi diagrams are a mathematical way to divide a surface in a crystalline pattern from random points. Every space inside the shapes is closer to one of the random points than to any other. You can create them by growing a circle around each random point until they intersect, and then you can draw a line between the intersecting points. I used an online random Voronoi generator to create mine.
The pattern appears in nature when mud is drying and cracking up, as well as in plants and animal life. It is also interesting because a three-dimensional Voronoi pattern, or foam, may describe the distribution of matter in the universe. If you place paint between two glass plates and then suddenly separate them, you see the pattern in the remains of paint on both sides. This is because when you separate the plates, the volume between the plates grows, and vacuum bubbles appear in it as the paint itself has trouble becoming thinner. The same happens when the universe expands. Matter sticks together because of gravity and nuclear forces, and the voids between them grow.

The title is Omega, after a parameter used in the calculations for the universe's expansion.
The average density of the universe determines its ultimate fate, whether it will eventually recollapse or expand forever. If the average density is a particular value, called the “critical density,” the boundary between these two scenarios will occur.
Astronomers often express the universe's density as a fraction of the critical density. The capital Greek letter (Omega) symbolizes this fraction.

So if (Omega) = 1, the universe is at equilibrium and has critical density.
If (Omega) < 1, then the universe is “open” and will expand forever.
If (Omega) > 1, then the universe is “closed” and will eventually re-collapse.
