The universe that we live in is an unimaginably large place. It is so big that it’s impossible for the human beings to comprehend things with the size scale. You cannot compare anything on earth or the earth itself to the biggest things in the universe. Astronomers are taking pictures of the objects and their each and every movement. The universe is full of gigantic objects. In our own galaxy, earth is the fifth largest, but it still is a million times smaller than the other objects that the universe holds.
Astronomers believe that it is the Lymann Alpha blob, a cosmic web, a super cluster of galaxies surrounded by dark matter; that accounts for ninety percent of the universe’s mass. What is this dark matter surrounding it? Dark matter is the matter without light that holds every structure present in the universe. It is a lot more complicated than anyone can ever imagine. It is untouchable; it has no smell and cannot be seen.
How this cosmic cluster originated is still a mystery, but it is highly believed that it was caused by the Big Bang. The cosmic matter contains everything created by the big bang and holds them together through huge strands of gases that tie the galaxies together. The huge clusters of mass are held together with gravity, but it is highly doubted if this gravity is strong enough to hold everything in the universe together.
Perhaps, there is more than one of these super clusters present in our universe. These super clusters of galaxies stayed together over time because they are tied by gravity and thus keep orbiting each other. Super clusters are the most crowded regions of the galaxy, but they are surrounded by equally big regions of empty spaces. These are called voids. Watch this History Channel documentary by Laura Verklan Armstrong and discover what creates these voids.
