Quasar Black Hole

[arvi1125]

Quasars are like inverted blackholes am i right? what are their purpose? if it is a collapsing galaxiy then how some some scientist say that they shine with the light of a trillion stars?

[memareaste]

@arvi1125 Quasars are not inverted black holes. They contain a black hole and what shines so bright is the matter that is orbiting the black hole. Since the black hole is small, the matter is squeezed and heated very strongly before it falls in. This heat is what makes it shine so bright before it disappears from view...forever.

[MeredithWaters]

The size comparisons made in the comments are interesting. What would help is knowing how quasars compare to galaxies. Anyone?

[fertilizerspike]

"Black holes" are certainly mysterious, but they are not objects in the universe, they are utterly fictional.

[godofmajora]

@rockhound404 Quasars are the hunks of matter that fall within the event horizon. Usually they consist of gas and dust and any other space material that fell too close too the gravity of a supermassive black hole. When the gravity of the black hole pulls it through the event horizon the mass superheats too several million degrees farenheight. When it goes through it is crunched. What the black hole cant "digest" is reduced too subatomic particles and spat out of it at 99% the speed of light.

[elgoikon]

Quasars ARE White Holes!

-In the center of a Black Hole created conditions are similar to those prevailing in the universe at time of Big Bang! (So, they can give another Ka Boom!)

-White Holes are provided by the theory of relativity

-The extreme Gravity Conditions Confounding Red Shift of the Spectrum of Light - provided for by the Theory of Relativity

-AND Findings of Radio Telescopes that there is a great Eruption of Gama ray straight from the center of Black holes!!!! (Simply Explosion)

[SGTjoppe]

thumbs up for the fitting song.

[lordsidyous]

That is so fucking awesome.

[SnieznyAniol]

While there was initially some controversy over the nature of these objects—as recently as the early 1980s, there was no clear consensus as to their nature—there is now a scientific consensus that a quasar is a compact region in the centre of a massive galaxy surrounding the central supermassive black hole. Its size is 10-10,000 times the Schwarzschild radius of the black hole. The quasar is powered by an accretion disc around the black hole.

This is what Wikipedia say :).

[SnieznyAniol]

A quasi-stellar radio source (quasar) is a very energetic and distant galaxy with an active galactic nucleus. Quasars were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that were point-like, similar to stars, rather than extended sources similar to galaxies.

[Lara24P]

No. The current definition of quasar ("quasi-stellar radio source"= almost star) is: nucleus of a galaxy, powered by the energy of matter that is being absorbed by the black hole (also in the centre... with millions of solar masses). The majority of quasars overshadows the galaxy around them, and are even brighter than a hundred billion suns! ;) (wow seems I´m getting expert in astronomy ahaha)

[stormyrose]

its just so small that it seems far away... things shrink next to it... but it looks like it can eventually spit the energy back out in a purer form...

[supergiuovane]

Black hole is just an ingredient of a QSO. The other is material -gas- falling onto it. Gravity and viscous forces will eat this gas so that it will emit a huge amount of energy (which is actually very well depicted in this video)

[DBCOOPER888]

I think Satan is really just a very bright Quasar.

[dilibau]

so what about his hell? just some gas swirling in...? that'd be disappointing...

[VORARATH200]

@DBCOOPER888

how wrong you are

[DBCOOPER888]

A quasar is powered by a massive blackhole, but it is not a blackhole anymore than a blackhole is a quasar.

[Rockhound404]

A Quasar is the Godfather of all Black Holes. It´s a collapsing Galaxy. A normal Black Hole is compared to this just an Atom. Sry if iam wrong but thats what I learned in school many years ago.

[Mac11A1]

@Rockhound404

A quasar is not a collapsing galaxy but actualy a galaxy in its early forming stages (;

[dilibau]

u r wrong.black holes don't have sizes, they are infinitely dense points in space: no volume, but a lot of gravity. What really defines them (and also differentiates them) is the mass: a super-massive BH is thought to begin at around a million solar masses. There are quasars that reach 13.2 billion solar masses, so yes, you'd be right to try a comparison between an atom and, for ex, the super-massive BH at the center of our galaxy (estimated at around 3 million solar masses)

[memareaste]

@dilibau The black hole does have a finite size. First, there is the event horizon and the formal singularity to which you refer, in Einstein's theory is a point with no size, but that is only because this theory has not yet been combined with quantum theory. When this is done, some day, the singularity will most likely turn out to be finite.

[memareaste]

@Rockhound404 The galaxy around is not collapsing, just a small part of the free gas and dust is slowly falling into the black hole at the center.

[LutonIrish10]

@memareaste It isn't slowly falling into the black hole in the centre. In fact it is accelerating towards the black hole at astonishing speeds, that is what produces the high frequency X-rays from quasars.

[kardeldavioncats]

@Rockhound404 It is not a collapsing galaxy it is a collapsing star!!! That have uses all of its hydrogen fuel!!!!

[average220]

Quasar is a black hole + more stuff like lazers

[RandomAnimationsInc]

A black hole isnt literally a hole... its a large star that caves into itself forming a super dense core capable of pulling light into it from the gravity

[memareaste]

Sorry, but religious comments, in favor or against god, have caused ugly replies among people. Since the subject of this video is not religious, I would like to ask people not to comment along those lines. I have removed previous such comments and will remove future ones. I hope both sides will understand.

Wo.

[tiffelau168]

it's like a space ballet.

[Davezmaan]

If a blackhole even had a minute impact on our planet, or anything we can construct and explore space with, we would die.

So a gate to heaven? Depends if we get sucked in spiritually.

[Guitar14k]

with a black hole we would disappear within secounds. Especially a quasar. So a gate to heaven? no. Search for "wormhole" and u might just find ur gate :)

[Suniclouds]

I think space is amazing, and i think quasars are pretty big destorying phenomini but seeing as they shoot out rays of "stuff" whcih i don't think they have sused out what they shoot out probably some gas atoms that have been compressed for thousands of years and then capow! out they come :D o.O will be interesting to find out what though :D

[iputaspellonU109]

Why do Youtube videos with subject matter relating to the Cosmos always have Classical music?

I mean,COME ON! Why can't we watch the Earth being sucked into a Black Hole to DMX?

WHY?

[MenkoKun]

Because mostly smart people are interested in this kind of thing, so should not care about something as insignificant as the song that plays during a 38 second video.

[iputaspellonU109]

Why do videos with subject matter relating to the cosmos always have classical music in them?

I mean,come on! Why can't we watch the Earth being sucked into a black hole with DMX in the background?

WHY!

[memareaste]

Good point. The problem is copyright. If someone sends me his own music that would work with this or similar videos I am working on right now, I'd be glad to use that music. Composers feel free to contact me! Wo.

[deusimperator]

@memareaste

Leave Beethoven 5 Mv1 memareaste. The symphony has a co-relation to astrophysics and mathematics. After all the universe is a beautiful symphony in itself. Play some rap or other crap and the video looses its meaning.

- a physicist and mathematician

[ggf51724]

me encanta, realmente

[LiLJampaBoy]

what the diffrent between a wormhola and a blackhole

[eric88eric88]

i wonder if black holes are portals to heaven but that is probably not true

[IIGoldManI]

heaven doesnt exist wurmholes are portals

[cephyric]

then heaven'd be a rather gigantic place, to hold all stars and matter absorbed by black holes, especialy the supermassive ones.

[seupagodeiro]

eric...dont say fool things, you can believe what u want, but the cience has bases,waht you said has not any value,in this case i can say that de duck donald is god, because "i believe",If you read more, study more physic, you will understand why s so fool waht you said...

[CHUBBLE117]

Every Galaxie in the universe that has some organized shape, has one of these massive black holes in the centre, that includes ours

[Superiorer]

A massive black hole sure, a Quasar is somethong different. With a quasar the rotational energy of the mass (stars, the whole galaxy) is radiating away. So it falls into the blackhole. In normal galaxies this doesnt happen so the stars spin around the blackholes for quite a while.

[bleed4weed1]

wow

[firefrog101]

For some reason its cute

[WowThatsCool13]

this is awesome

[blusior]

Wonderful video,but too short.But thank YOU
