The void of the universe

At the very largest scales — zooming out from solar systems, stellar clusters and even galaxies — a surprising pattern emerges in nature. When you zoom out far enough that entire galaxies (each one home to hundreds of billions of stars) are just single dots of light, you'll find … a web. Long, thin ropes of galaxies millions of light-years long. Dense, compact, massive knots of thousands of galaxies — the clusters. Broad, thick walls and sheets of even more galaxies.

The cosmic web.

Cosmic voids (also known as dark space) are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. The cosmological evolution of the void regions differs drastically from the evolution of the Universe as a whole: there is a long stage when the curvature term dominates, which prevents the formation of galaxy clusters and massive galaxies. Hence, although even the emptiest regions of voids contain more than ~15% of the average matter density of the Universe, the voids look almost empty for an observer. [1] Voids typically have a diameter of 10 to 100 megaparsecs (30 to 300 million light-years); particularly large voids, defined by the absence of rich superclusters, are sometimes called supervoids. They were first discovered in 1978 in a pioneering study by Stephen Gregory and Laird A. Thompson at the Kitt Peak National Observatory.[2]

The Cosmic Void: Could we be in the Middle of it?

Now it's easier to send The void of the universe a message.
