The Largest void in universe Discovered

Astronomers have detected the universe’s largest known cosmological supervoid in the Southern constellation of Eridanus.  Spanning some 1.8 billion light years !!!!!!!

(1 Light Years ~ 9 Trillion Kilometer)

It might be the single largest structure ever in the universe, and the only sign of it is nothing – just empty space 1.8 billion light years across. That’s 18,000 times larger than our entire galaxy.

the team remains mainly baffled as to why such an extensive void — in which the “density of galaxies is much lower than in the known universe” — could have actually arisen.

“This supervoid is certainly rare,” Greg Aldering, a cosmologist at Lawrence Berkeley National Lab in California, told Forbes.  “Underdense by about 30 percent, it’s not completely empty.  But what’s rare is the [spatial] extent of this void itself.”
