What we call a quasar is really the ultra-heated accretion disk outside of a supermassive black hole. A quasar is more of a state of an accretion disk than a distinct object in itself.
The accretion disk almost certainly extends inside the event horizon of the black hole where it releases even higher amounts of radiation, but all that radiation is bend ...
You can say that if a object has kinetic energy in the vicinity of a massive object it has potential energy.
And if the angle bitwext the radial vector and velocity vector
Is not 0 or 180 secs
The object has angular momentum
And a path with angular momentum
Light has kinetic energy so it can be bent by Newtonian gravity.
In fact I can’t swing by a ...
the Quasar Age or Quasar Epoch has ended.
As pointed out by James K., the Quasar epoch has not ended. Today quasars are rarer then some Gyr ago, but they are still here. The closest one is about 600 million light years away and it is receding at about 12500 km/s, which is 4% of the speed of light. This fact alone proves that quasars are not a consequence of ...
tl;dr, General relativity is really hard, you need a lot of visuals; no one visual is necessarily better, they all help illustrate different properties. Use all of them you can, and try to learn some analytical methods if you haven’t so that you have access to more intuition-building diagrams.
Now to dive into it; the answer is a bit complex.
There’s a ...
