1) The impossible giant:
The Milky Way is quite big.
It is one hundred thousand light years in diameter, that is, if we were to travel in a science fiction vehicle at the speed of light, it would take one hundred thousand years to travel through our galaxy.
Now imagine the LQG, which is four billion light years across!
It is a structure formed by seventy-four quasars, and it breaks the rules of astrophysics - the maximum size of any cosmic structure should be only 1.2 billion light years.
Scientists have no idea how LQG formed.
2) The largest water reservoir in the universe:
Anyone who thinks that planet Earth is the place where there is more water is wrong.
12 billion light-years away is the largest reservoir in the universe - at the center of a quasar.
It has 140 trillion times the amount of water in our planet's oceans.
However, being close to a colossal black hole, the water manifests itself in the form of a huge cloud hundreds of light years across.
3) Ghost particles:
Neutrinos are a type of elementary subatomic particle - that is, there are no smaller parts inside them - and are similar to electrons, except that neutrinos have no electrical charge and are 6 million times lighter than the mass of a electron.
They are so tiny that scientists call them "ghost particles".
They are highly volatile, practically do not interact with matter and are unaffected by magnetic fields.
In other words, they travel billions of light years through matter, without ever changing direction. They pass through planets, stars and galaxies like mini ghosts.
They are passing you right now! However, neutrinos play a significant role in how galaxies are distributed through space.
