Quasars are billions of light years away? They are the most distant objects in the universe? Clearly that should tell us that quasars were more common billions of years ago...perhaps they do not exist at present where we are seeing them. Insights and thoughts please!
@fertilizerspike If physics is not your specialty, then I suggest you don't conjure up theories of your own and ask yourself who really is being asinine and ignorant.
@fertilizerspike There is an overwhelming amount of evidence for black holes. I don't recall any astrologers citing black holes in their daily horoscope predictions.
The thing is that Ultraviolet and optical radiation from quasars perfectly match an emitted spectrum from a very hot viscous and rotating disc, so there are indeed evidences. But also from X-ray and radio observations: different emission mechanisms (synchrotron, inverse-compton, scattering) all converge to a common explanation.
The fact that it is not observed.But it's not me saying so, it's astrophysicists.The kind of radiation emitted by quasar is very well explained by matter infall,and that's it. Try google: Eddington accretion, non-thermal emission in qso, graviational energy release. This kind of energy production is more efficient than nuclear fusion.
It does, actually, constitute an evidence. While there is no evidences for white holes. There are a bunch of proofs for BH as the engine in quasars and AGNs: the gravitation-doppler shift of spectral lines emitted in the x-ray, the increase of the motion of gas as you go closer to the BH.What emits most of the light is the accretion disk onto the black hole
Well, first of all colours,at radio frequencies, have no meaning. Second, you cannot spatially resolve a structure like this one, at such large distances, not even with radio telescope with large baseline. What you can observe is the structure as a whole (BH+accretion disk+jets+dusty torus)
Well, probably because you don't know a lot about plasma physics, relativity and quantum physics. An accretion disk, anyway, can extend up to a parsec. Google quasar or AGN, you'll find out a lot about this
No, it's not. What powers a quasar is a supermassive black hole, who is accreting matter at a very high rate. THis matter is distributed in a disk which is spinning around the black hole. Viscous forces in this accretion disk heat the disk up to hundred of thousands degree, and this produce an extremely high luminosity.
the black hole is somehow the engine of the light which is produced by matter accreting onto the black hole itself. The enormous gravity and hence friction produce the light we see
Dr. Halton C. Arp (4:29) catalogued a list of peculiar galaxies that today are known by his name. A prominent example is Arp 274, the winning target in the Space Telescope Science Institutes 'You Decide' competition in celebration of the International Year of Astronomy (IYA).
Quasars are galaxies at the early age of universe. At that time, supermassive black holes at the center of the galaxies sucked in vast amounts of gas that were abundant then and generated huge amounts of energy from the infalling matter. The source of the energy in quasars are only a few light months across, further suggesting black holes are responsible for the engery generated.
Can a Quasar form in modern days? What if 2 galaxies collide today and the 1st galaxy's supermassive black hole suck much matter from the second galaxy? For a Quasar to happen, the matter to be sucked into the black hole, has to be only gas or not (say an other thing such giant stars from a galaxy collision).
these questions are all sounding like other questions,,,
can humans have, close range contact, can they be obsorbed or morphed by human hands, or even , could it be fused into a energy source, for better efficant models?? and by the way,,
have you ever seen the light up close, and have you any control on it ???
black holes dont explode a black hole is defined as an infinity small object left over from a collapsed star, all it is is the leftover matter from the star in a very very dense infinatley small object but quasars are believed to take all of the energy (radio waves etc.) from nearby black holes
maybe the eagle is looking back at the egg.. and the quasars are no longer there because they have already become the galaxies that they are observed to be flying away from..
we cannot assume that they are in the present, that the 'are' .. but we can know that they 'were'..

His conclusion was quasars are ejected from nearby galaxies. Had some trouble with the video here.

Ah, sorry for not reading the reply to his comment before making one myself, you just have to admit that it was timed horribly well lol
thanks for the upload in general though
