Confronting the Cosmic Voids: Embracing Our Place in the Universe
Confronting the Abyss: A Journey Through Cosmic Voids Friedrich Nietzsche once proposed that when we gaze long enough into the abyss, it gazes back into us. Yet, in my reflections on the vastness of the universe, I find that the void remains silent, relentless, and profoundly intimidating in its enormity. When we peer into the infinite blackness that characterizes the cosmos, we face a pivotal…
New test of dark energy and expansion from cosmic structures | News | University of Portsmouth
The study uses a new method based on a combination of cosmic voids – large expanding bubbles of space containing very few galaxies – and the faint imprint of sound waves in the very early Universe, known as baryon acoustic oscillations (BAO), that can be seen in the distribution of galaxies. This provides a precise ruler to measure the direct effects of dark energy driving the accelerated expansion of the Universe.

The Strange Case Of The Pushy Void
The Strange Case Of The Pushy Void
The Strange Case Of The Pushy Void By Judith E Braffman-Miller Billions upon billions of galaxies, blazing with the furious, brilliant fires of a host of dazzling stars, trace out the heavy and gigantic filaments of the Great Cosmic Web–a structure that would otherwise be invisible to our eyes, were it not for these sparkling and revealing flecks of starlight. This mysterious Web, which is…

An article published in the journal "Monthly Notices of the Royal Astronomical Society" describes a research on the distribution of matter in the universe. According to the results 20% of ordinary matter is contained in the so-called cosmic voids and galaxies are only 1/500th of the volume of the universe. A team led by Dr Markus Haider of the Institute of Astro and Particle Physics at the University of Innsbruck in Austria, has used simulations of the Illustris project to reach these conclusions.
Black holes banish matter into cosmic voids In recent decades, astronomers have cultivated a picture of the universe dominated by unseen matter, in which – on the largest scales – galaxies and everything they contain are concentrated into honeycomb-like filaments stretching around the edge of enormous voids.

Paul M. Sutter
While Pamela and Fraser were at Ohio State University for a symposium in October, they caught up with Paul M. Sutter from Astronomical Observatory of Trieste, who is a visiting scholar at the OSU Center for Cosmology and Astro-Particle Physics. His specialty is cosmic voids. Paul also hosts the podcast “Ask a Spaceman.”
