Introduction
Brief Overview of the Universe’s Structure
The universe is a vast tapestry woven with galaxies, stars, and empty spaces known as cosmic voids. These voids, which appear as vast, dark gaps in the cosmic web, offer a unique perspective on the universe’s large-scale structure. Among these, the KBC Void stands out as the largest cosmic void ever known, challenging our understanding of the universe and its formation.
Introduction to Cosmic Voids as Vast, Empty Regions of Space
Cosmic voids are immense, nearly empty regions in space, devoid of galaxies and other forms of matter. They are critical components of the cosmic web, the large-scale structure of the universe, characterized by a network of galaxy clusters and filaments separated by these voids. Among these voids, the KBC Void, discovered by Keenan, Barger, and Cowie in 2013, stands out as the largest cosmic void.
Introduction to the KBC Void as the Largest Cosmic Void
The KBC Void, named after its discoverers, is the largest cosmic void estimated to be 1.3 billion light-years in diameter. It represents one of the most significant discoveries in cosmology, challenging our understanding of the universe’s structure and the distribution of galaxies and matter.
