That there is a black hole several hundred billion km wide?
Hell yes

Me too. I'm actually thinking about majoring in astronomy, not sure it really pays well though :(

You need to know ALOT of math for astronomy.It requires alot of calculations to move the telescopes.

Black holes aren't that big. Black holes are usually smaller than a small star until they start collecting mass.

Please research on what I said more than a year ago before saying anything

S5 0014+81
I wonder how big that one is
hmmmmmmmmmmmmmm

I know my astronomy. I was saying on average they aren't that big. They're one of the smallest large bodies of mass. E.g. stars, planets,neutron stars. Secondly, after looking up your example, S5 0014+81 I found out isn't even a black hole it's a whole galaxy.

The fact that you don't know the difference between a galaxy and a black hole is worrying. Also the fact you said it over a year ago has no relevance to the accuracy of it, if the information you provided is wrong..

''That there is A black hole several hundred billion km wide?''
A isn't plural dude, again, read
And that Black hole isn't an entire galaxy, It's a quasar. Can you link some stuff to show it's a galaxy?

Please show how an infinitely dense object is a galaxy
Galaxies usually have them at their centers but they aren't the same thing dude

"And that Black hole isn't an entire galaxy, It's a quasar." A quasar is a part of a galaxy. An active galactic nucleus (AGN) is a compact region at the center of a galaxy

I just said Bholes are at the centers of galaxies usually jesus christ dude
i know we are talking about dense objects but stop being one

You said S5 0014+81 is a black hole. It isn't, it is a quasar. Your points are contradicting each other. Also you're editing your posts after I have already replied.

I edited one post to merge 2 comments.
''Quasars, also called as quasi stellar radio source, is a very bright object in the universe. It is basically a super massive black hole in action.''
Basically the same thing, just that Quasars are sucking in big dust clouds. The posts aren't contradictory at all. Maybe confusing, but not contradictory...

''Quasars, also called as quasi stellar radio source, is a very bright object in the universe. It is basically a super massive black hole in action.''
Same thing, just that one is bright and interacting with dust clouds.
And I merged 2 posts.

And you said S5 0014+81 is an entire galaxy, now you're saying it's a quasar? That's more contradictory.

And just because a Quasar is part of a galaxy doesn't mean that it's the entire damned thing

A quasar is a type of galaxy. "Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies" Here is a link https://en.wikipedia.org/wiki/Active_galactic_nucleus#Types_of_active_galaxy

S5 0014+81 Is a Quasar therefore is a galaxy.

"Same thing, just that one is bright and interacting with dust clouds." Black holes aren't bright. They're literally invisible as light can not escape them. Also as you've already said "basically a super massive black hole in action". This statement is saying they are not the same thing. There is a difference between a mass that has gravity so powerful light can't escape it and shiny dust.

There's a big rotating shiny thing that's millions of degrees in temperature swirling around a black hole making it bright. That's what is called an accretion disc...You should know this, yes? As it says in the definition, it's just a black hole in action.

It's an AGN, they just are on the centers of galaxies, and define the galaxies they're in.
Saying that they're galaxies by themselves is odd because it doesn't fit with the usual definition of one. By itself it's not a collection of stars rotating around a common center.

Please go back and complain about SJWs and Liberals because you can't speak about astronomy without contradicting yourself all the time

chuk me
