Is Quasar much more powerful than black hole?

[visser300]

I read an article in wikipedia an it said that the most strongest quasar in observable universe could produce an energy that equals to 2 trillion sun per second!!!

I just 'wow, that's real '. But wikipedia is not a reliable source so I hope you guys could enlight me a little bit. If the strongest quasar and the biggest black hole in this universe colide, what will the consequence of the event?

[Magicman2051]

Nothing.

That said though we'd have to understand both phenomena to be sure.

Gravity seems to have a distance at which it no longer effects so I figure if it's far enough we won't even notice. We don't understand Black Holes, we just know they exist and that Gravity is a major factor therof, them coming from imploded stars is a theory that cannot be proven in our lifetime.

Quasars are few and far between and are nearly just as illusive as black holes. Number crunching at the likes of 2 trillion times is highly unlikely in my opinion, probably a guestimate.

All my facts are from watching Youtube videos so I could be wrong though.

Are you sure that gravity has a distance where it no longer effects? Or is the effect just impossible for us to measure? I've not seen any studies on this matter so I don't know but I have to say that I am interested because it is probably very important to settle. Because if gravity didn't have a distance in relation to mass then theoretically the entire universe would act upon itself in a gravitational pull. I don't see that as being extremely far fetched myself to be honest.

As far as we know, gravity has the same effective range as light. It just becomes negligible at such distances. As for the "great pull" I assume you mean the Big Crunch? A sort of inverse Big Bang? Because after the discovery of dark energy (which isn't a discovery per se, because we don't yet know what it is), that model has been largely abandoned.

@OP, that would depend on where it happened. Because of the (accelerating) expansion of the universe, if it happened more than 16b LY away, the energy from the event would never reach us. But if such two celestial bodies came close to earth, earth would be ripped apart and fried by gamma rays. As far as apocalypse scenarios go, it is a pretty cool way to exit the stage.

Michio Kaku the Physicist holds this belief because the pull of gravity is infinity + infinity + ... ( forever and ever ) so if this was true then gravity must dissipitate after some distance from the source otherwise would it not be true that the universe would constantly be ripping itself to pieces as the pull of many inifite gravity bodies infinitely try to pull each other.

Gravity has infinite range per the popular formula F=G(m1*m2)/(r^2) and as far as I am aware, has no "reaction speed".

Then explain why something with infinite infinities of gravitational pull does not have everything in the universe pulled into it?

It does. Every single atom in the universe has a pull against every other atom.

[Alkaline Earth]

We're certainly not seeing that though, unless black holes actually tear space ( which we have no proof of ) then everything in the universe should instantly be sucked into something that has infinite gravity, infinity is a big number.

Black hole's don't have infinite gravity. I don't know where you came up with that idea.

You can't really compare them. A quasar has a super-massive black hole in it's center. It's basically a huge black with a lot of matter spinning around it.

Gravity has infinite range per the popular formula F=G(m1*m2)/(r^2) and as far as I am aware, has no "reaction speed".

If I remember correctly there is actually and it is the speed of light. So, if the Sun suddenly disappears then the Earth will observe the effects of it about 8 minutes later.

Black holes have the same amount of gravity as the star that produced them. If the sun turned into a black hole tomorrow, nothing for earth would change. Well, except for the loss of sunlight and all the energy required for life....

You have to be more precise.

Michio Kaku believes that a black hole has infinite gravity due to the mathematical equations. I am no physicist expert ( I'm 15... ) but he is, so I kind of trust him on this, whether it's true or not I don't think we can prove, but if we accept the equation then don't we need to trust that the results of the equation are true?

Can you provide the minutes and seconds into the video where he reaches that conclusion?

That clip shows how the Newtonian force of gravity breaks down at the center of a black hole. The mass of the black hole, say a former sun like star, is the same as its former sun. Hence its gravitational force at distance r from earth is going to be the same as it was before. The problem the good doctor is illustrating is that all that mass from before is crushed down into a singularity at the center of the black hole. As we approach the center of the black hole r approaches a value of zero. This means that the Newtonian understanding of gravity breaks down. Infinite gravitational force.

I've always found this YouTube video to be containing great images:

All stars spin. When a spinning star collapses into a black hole it continues to spin to preserve angular momentum. Thus matter in the accretion disk of a black hole orbits in the direction of the spinning singularity.

The velocity of the atoms in the accretion disk strips them into protons and electrons. The black hole acts as a spinning dynamo creating an electromagnetic field. Not everything in the accretion disk can cross the event horizon at the same time, so two opposing jets of charged particles escape from outside of the event horizon.

When scientists first observed a quasi-stellar object, or quasar, they were actually observing one of the jets that was pointed directly at us. So a quasar is merely an accreting black hole as viewed from the direction that one of the jets is pointing.

Also, the singularity of a black hole has a volume of zero. The mass of the singularity divided by its volume gives its density. So mass divided by zero gives a density that is infinite. The gravity does not become infinite.
