In the observable universe , The total number of galaxies may reach more than 100 billion . Most galaxies are between 1,000 to 10,0000 Second gap , The distance between each other is in the order of millions of seconds . Intergalactic space ( Exists in the space between galaxies ) Filled with extremely thin plasma , The average density is less than one atom per cubic meter . Most galaxies will be organized into larger groups , Become a galaxy group or cluster , And galaxy clusters converge into larger superclusters . These larger groups are often referred to as large-scale fiber structures , Distributed around the huge holes in the universe .
