Quasars - short for "quasi-stellar radio objects" - are believed to be the super-massive black holes in the cores of large galaxies as they are in the process of forming, merging, and consuming nearby stars and star systems. It is likely that our own Milky Way was once a quasar, but that the super-massive black hole has already consumed most of the nearby mass and settled down to a tranquil old age.
The things that we observe as quasars are believed to be caused by huge black holes.
Quasars are thought to be distant super-massive black holes.
Some scientist think that quasars may be caused by black holes, but they are not sure how this happens. Please dont copy. Use your own words! - Anonymous <3
Quasars are related to supermassive black holes in the center of galaxies.
No, a supermassive black hole is what makes a quasar.
Yes. Several quasars have been discovered; they are black holes, and they are quite active.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
The writer may be referring to the theory that black holes could spawn new universes (Smolin's Fecund universe). This is highly theoretical is a along way from being proven.
Each black hole and each quasar is the remnant of a single extinct star.

Scientists think quasars are supermassive black holes in the process of consuming enormous amounts of matter.
Quasars are small because they are powered by supermassive black holes at the centers of galaxies. The intense energy emitted by the accretion of matter onto the black hole creates a very compact and luminous source in the center of a galaxy.
