many believes that quasars are the opposite end of black hole. I don't thinks so?

Question

many physicist put forward this wild idea that quasars are the opposite end of the black hole. I dont agry on it, because at one end gravity is not allowing even light to escape from it, how come the ligth can escape from the other end? is gravity acts only in one direction? i dont agree with it. if any one have good idea to have explaination to this wild idea pleas let me know.

Answer 1

In the 1980s, unified models were developed in which quasars were viewed as simply a class of active galaxies, and a general consensus has emerged that in many cases it is simply the viewing angle that distinguishes them from other classes, such as blazars and radio galaxies. The huge luminosity of quasars is believed to be a result of friction caused by gas and dust falling into the accretion discs of supermassive black holes, which can convert about half of the mass of an object into energy as compared to a few percent for nuclear fusion processes.

Answer 2

Actually, I have heard that a hypothetical object called a WHITE HOLE is the oppostie of a black hole; a white hole and a black hole are connected through space, but a white hole spews out the material that the black hole on the other end has sucked in. I don't think that white holes have been proven as fact, though.

A quasar is thought to be a supermassive black hole at the heart of a galaxy. When the black hole is actively sucking in material the whole region around it will glow fantastically bright...this is what people call a quasar. Most galaxies are thought to have these supermassive black holes at there centers; the Milky Way might have one (stars at the center of the galaxy appear to be orbiting around something there unusually fast), but I don't think that this has been proven yet.

Answer 3

You're right in not thinking so. The latest thinking is that quasars are simply ancient gigantic black holes. The radiation coming from them is the result of the accretion disk - swirls of matter spiraling into the black hole on the plane, some ejection from the poles. The radiation that comes off such a quasar is coming from matter that swirls into the black hole, but outside of the event horizon - so that photons can actually escape the black hole because they were emmitted from a far enough distance.

Answer 4

Quasar stands for qausi-stellar object. That is quasars appear like stars through a standart telescope, but are much further away from us. In fact, quasars produce 100-1000 times as much energy as your average galaxy made up of something like 100 bill. stars. Nearly all scientist agree that the only thing powerful enough to cause this phenomena is a supermassive black hole. Thusly, quasars aren't the opposites of black holes, they are powered by them. You must have misunderstood.

Answer 5

Well look at it this way: is it logical to think that everything sucked into a black hole is simply obliterated? That doesn't make much sense either. "Stuff" has to go somewhere.

I'll toss out my remedial knowledge of physics (attained through PBS, Discovery, etc.) and formulate a hypothesis here. Perhaps the blackhole leads to another "universe", parallel to our own. Something like string theory suggests. Though the universes are separated by membranes, maybe a blackhole/quasar connects the two. We could, in theory, move from universe to universe by leaping through these portals.

Answer 6

No they don't.

Most physicists believe that quasars are caused by accretion disks around super massive black holes.

Answer 7

A quasar is black hole. It is just a very massive one.

Answer 8

Neither do I believe in this..
