Boötes void

Boötes void is one of the largest known voids in the Universe. This massive empty spherical region in space is about 330 million light-years in diameter. The Universe is full of voids! Areas where very few things exist. Boötes void or the Great Nothing is such a place.

Could the many stars whose brightness has dimmed be indicative of Dyson Spheres or other Megastructures? Could the Cosmic Voids vastly bigger than any galaxy be the work of even greater and older starfaring species?

In this episode of Ask an Astrophysicist, Dr. Sam Morrell answers Lexy's question of: "What is the Boötes Void"? With Natalie asking some follow-up questions, he explores how this supervoid came to exist and why we can't seem to see anything behind it.

Supervoids are the massive, empty spaces between galaxy clusters and galaxy filaments. But just because they are empty, doesn't mean they can't be fascinating! They have taught us a great deal about galaxy structures and the early universe, and today we'll be venturing into a few of the biggest! Do you use these videos to sleep or for night time watching?

Supervoids are some of the largest, emptiest regions of space in the entire Universe. Their very existence proves that the expansion of the Universe must be accelerating; by studying them we can therefore probe the mysterious dark energy… You can pre-order my book ' Space: 10 Things You Should Know' as a hardback (UK only) or e-book (worldwide): http://bit.ly/SpaceDrBecky Krishner et al.

Bootes Void is a really strange empty area in space. Total obscurity. These cosmic voids are the biggest things in the universe. In this video, you will get an idea of what these dark places are.

The Fermi Paradox asks us where all the alien civilizations are? Today we will ask if the might be hiding in the Voids, from those between the stars to the massive Supervoids like the Boötes Void. Could they be home to Extraterrestrial Empires so large they dwarf even Kardashev-3 Civilizations?

The Boötes Void is giant super void spanning 250 million light years across with almost nothing in it. Its existence has challenged astronomers for decades. Follow me!
