Apparent Space Voids
My first instinct is that this is not real. If we could go there, I would expect that the hole would simply disappear. However that demands that all the light arriving from that part of space is passing through a lens that is seriously close enough to us to bend light yet far enough to not display actual movement. Good luck on that.
Alternatively we are looking a region of dense neutral neutrons that has simply failed to coalesce sufficiently to produce the cycle of matter and star building that would make it visible. We may simply have lacked a useful compression wave passing through to trigger star building in particular.
As we have posted before the universe is full of matter that has simply not decayed and then accumulated sufficiently to reach detection levels. While filling the universe is no trick, actually triggering decay and accumulation may well demand a lot more in terms of luck and that is strongly suggested as well by the obvious fine structure.
Colossal ‘Hole’ in Space Could Be Link to Universe Beyond Our Own

Leave this world, travel 6 billion–10 billion light years toward the Eridanus constellation, and you’ll run into a giant cosmic wall of nothingness.
A void in space 1 billion light years across stumped scientists when it was discovered in 2007—then another void spanning 3.5 billion light years was discovered in 2009. These voids cannot be explained by the current understanding of the universe’s structure and evolution.
It is said that smaller voids have formed by gravitational pull following the Big Bang. But voids of this could not have formed in the amount of time following the Big Bang, they would require much more time to form.
So What Are They?
They contain neither galaxies nor clusters, explains a New Scientist article, and infrasonic mapping has shown the Eridanus void to be cold, suggesting it lacks dark matter.
“Standard cosmology cannot explain such a giant cosmic hole,” Laura Mersini-Houghton, a researcher at the University of North Carolina, told New Scientist. Her theory: “It is the unmistakable imprint of another universe beyond the edge of our own.”
Astronomers hypothesize about the voids, but no conclusions have been reached. It remains a mystery.
Mount Sumeru and other mystical mountains discussed in Buddhism are sometimes said to be real structures in the cosmos made of substances not easily perceived by mankind and which thus appear as gaping holes.
Putting the Numbers in Perspective
The known universe is estimated to be about 93.5 billion light years across, meaning the void spanning 3.5 billion light years takes up about 3 percent of the universe.
