That's the current best guess; the formation of extremely powerful black holes in the centers of many galaxies. It's possible that when the central black hole in the Milky Way was forming, our own galaxy might have shined like a quasar.
This may be why we never see any aliens in space; any civilization that existed then might have been exterminated by the radiation released when the central black hole formed. Earth's biosphere formed after that, and we might be one of the first spacefaring species since.

∙ 11y agoA quasar is not a type of black hole, but it is a phenomenon that occurs in association with one. A quasar is a disc of superheated material spiraling in toward a supermassive black hole. Material that can't reach the even horizon is ejected in two polar jets at nearly the speed of light.

∙ 8y agoNo. Stellar mass black holes form when massive stars die and their cores collapse. It is unknown how supermassive black holes form. Quasars are a product of supermassive black holes that form when more matter falls toward one than can fit through the event horizon.
Wiki User
∙ 8y agoQuasars are believed to be caused by supermassive black holes. Those are black holes that have a mass of millions, or billions, of solar masses. More specifically, to "active" black holes - that means that, at the moment we are observing - lots of matter is falling into the black hole.
Wiki User
∙ 12y agoIn order to form a black hole, you must have at least (about) five times more mass than exists in our Sun. To me, at least, that's pretty massive -- ie, that's a LOT of mass.
Wiki User
∙ 12y agoYes, because quasar is an enormously bright, distant galaxy with a giant black hole at it's center.
Wiki User
∙ 8y agoNot exactly. A quasar is believed to be a mass of superheated matter falling into a supermassive black hole.
Wiki User
∙ 8y agoBased on our current understanding, a quasar is extremely hot matter on the verge of falling into a supermassive black hole.

What would happen if the quasars are near the earth?
Quasars are galaxies which are much brighter than ordinary ones. they are as bright as 100 galaxies put together. they are also as powerful as several blackholes put together. quasars are seen as faint light from the earth this shows how powerful they are to be seen from the extreme end of the visible universe in any case if the quasars were any nearer to the earth the earth would be pulled into by the ultra strong black hole due to the extreme intense gravity.no information in the form of light or radio waves would come out of it, its presence can be inferred only from the gravitational force it exerts on the bodies close to it
At what time will the black hole come?
Cygnus X1 is probably a black hole. There is certainly a black hole at the center of our galaxy. Most quasars are likely similar super massive black holes, swallowing continuous streams of matter and ejecting bipolar jets of matter and radiation arcing out hundreds of thousands of light years. Black holes have existed for billions of years--through a significant fraction of the age of our universe. It has been hypothesized that in the early moments of the big bang quantum black holes may have been created, but Stephen Hawking showed how these should evaporate fairly rapidly.
How come all stars don't form into black holes?
A black hole forms only when the star is large enough that the gravitational pressure exceeds the quantum degeneracy pressure.
Black holes refer to?
black holes come from dead stars like our sun it may turn into one when they die they become really big then explode and some become into a black hole if not it becomes into a black or white dwarf
How can astronomers detect where black holes are if no form of radiation can ever get out of a black hole?
There are two ways of detecting black holes indirectly. First, it is possible to observe the effects of a black hole's gravity on nearby objects. Second, while no radiation can come from within a black hole's event horizon, mater that has not yet crossed can still be seen. If a large amount of matter is falling toward a black hole, then it can become superheated and emit intense x-rays.
What rotates beside planets?
solar systems, moons, asteroids, galaxies, stars, quasars, black holes, dust clouds, just about everything come to think of it!
What are the dangerous in the space?
quasars (black holes), comets (if they come too close) and hyper nova(only of sun but it will take 5 billion years to do so)
What are the most dangerous things in space?
quasars (black holes), comets (if they come too close) and hyper nova(only of sun but it will take 5 billion years to do so)
How powerful are black holes?
Black holes are so powerful, that if you were in one, it would stretch you apart and you would NEVER come out!!!
How are black holes most easily identifed?
Black holes do not emit light, so black holes can not be seen this way. But black holes emit X-rays, but stars are not hot enough to emit X-rays. When black holes suck up stars, energy goes to the black hole, and come out as X-rays.
Where did a black hole come from?
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
Did the Black Death come to Canada?
No it did not come into Canada, as Canada was not discovered by Europeans yet. However, the Black death usually refers to Bubonic Plague so if you are talking about modern times the Black death did come to Canada. However, most would agree, the Black Death did not come to Canada
When did the black death come to the UK?
1665
Why do stars rotate around black holes?
because stars come from the blake hole
Do black holes come near each other?
We aren't certain, because 99.9% of what we THINK we know about black holes is theoretical. But the theory says that if two black holes do come too close to each other, they will merge to form one larger one. However, if the geometry of their approach is right, it might be possible for them to orbit each other.
What year did the Black death come to England?
1348
Did the black death come from rats?
yes, it certainly did. In Mongol army camps rats died and spread Black Death.
