The high luminosity and redshift of quasars suggest they are located at vast distances from us and moving away at high speeds, which is inconsistent with a steady-state model requiring a static and unchanging universe. Additionally, the lack of young quasars in closer proximity to us contradicts the continuous creation of matter needed in a steady-state model.
Quasars are the unusual type of active galaxy in the universe.
Quasars are not gone; they are still observed in the universe. Quasars are powered by accretion of material onto supermassive black holes at the centers of galaxies, which can make them appear as some of the brightest and most powerful objects in the universe. However, the number of observed quasars may be influenced by factors such as the current stage of galaxy evolution or observational limitations.
Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
Quasars being most common at a redshift of around 2 means that they were more prevalent in the universe's past. The redshift indicates their distance and age, suggesting that quasars were more abundant when the universe was younger. This redshift value corresponds to a time when many galaxies were undergoing intense star formation and black hole activity, leading to more quasars.
Quasars help us determine the large-scale structure of the universe, as their distribution gives insights into the overall mass distribution of galaxies and dark matter. They also provide valuable information about the history of galaxy formation and evolution, as well as the properties of the intergalactic medium. Additionally, quasars serve as powerful probes for studying the physics of supermassive black holes and their influence on surrounding matter.

Quasars are brightly glowing powerful "engines" of the Universe. Usually they surround black holes and glow when material funnels in. According to Astronomer Maarten Schmidt there are 100 times less quasars now than 10 billion years ago.
Yes, quasars are the most luminous objects in the universe.

There are about 12,000 known quasars today. I'm sure that as our telescopes get better, that number will go up. As a guess, I would estimate a lot.

A huge structure of pulsars/quasars which defies the cosmological constant.

No, quasars are not part of the solar system. Quasars are extremely distant and energetic objects located in the far reaches of the universe, millions or billions of light years away from our solar system. They are powered by supermassive black holes at the centers of galaxies.
Quasars are thought to be the centers of distant galaxies where supermassive black holes are actively accreting matter. The intense energy emitted by this process makes quasars some of the brightest objects in the universe. Studying quasars can provide valuable insights into galaxy formation and evolution.
