Black holes are one of the most mysterious objects in the universe. Quasars are one of the brightest objects in the cosmos and they are powered by gigantic black holes which swallow gas from their surroundings. They are located in the centers of remote galaxies. Our own galaxy has a small version of such a black hole in it's center, but there's not enough gas to produce the quasar phenomenon.

This video was produced to illustrate a a discovery about X-ray observations published in the scientific magazine NATURE by Marscher et al. (2002). The tools used for the animation where 3DStudioMax combined with the Afterburn Plugin.

  • 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?

  • @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.

  • 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.

  • 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)

  • @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.

  • @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.

  • 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.

  • @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.

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

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

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

  • @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.

  • 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)

  • thumbs up for the fitting song.

  • That is so fucking awesome.
