The usual view again blames a black hole, but if you accept the above explanation for radio galaxies, this will be simple: A quasar is gas becoming a galaxy. We call the quasar the part we can see, but the invisible part is a gas spread out much farther than a galaxy size. This gas can't compress into a galaxy with all of the energy it has, but when the quasar shoots out the stream of ions, the gas gets rid of enough energy to allow the cloud to shrink because of the force of gravity. A quasar is another disk generator radiating the overload from time to time in a galaxy about to be born.
A quasar is the fetus of a future galaxy.
HOW BIG AND OLD IS THE UNIVERSE
In certain places in the universe, galaxies tend to group and float along together, and we have thousands in our group. With a survey of about a million galaxies, astronomers have found an even bigger pattern.
Dozens of galactic clusters form thin strands, perhaps a billion light-years long. These strands can be called, guess what, filaments. There's more: The filaments lie somewhat parallel to each other as if there were an even bigger structure to the universe.
To create patterns like this takes at least one hundred billion years, or maybe trillions, for galaxies to take their places. The fifteen billion years of the Big Bang is not enough time.
