If light speed is so fast then how fast is these jets expelled from blackholes

[Chrysley]

Bro, I'm confused. These are excess matters that is being sucked by Black Holes. Now, if light itself cannot escape from it, then how do these Matters, excess gas being released? They should have a velocity faster than light if they can escape the pull?

I'm too tired to explain it early in the morning so I'm just going to quote a portion of a Cornell university paper on blackholes and quasar jets:

"Black holes suck material toward them, but some of it gets spit out rather than swallowed. Many black holes eject jets that move away from the accretion disk at nearly the speed of light. These jets have been observed most spectacularly from the centers of nearby galaxies (for example, M87) but also appear in microquasars - in quick, enormously energetic spurts and sputters, as if someone had taken a video of a quasar jet and pressed the fast-forward button.

The processes by which these jets are formed are not well understood, but seem to require magnetic fields - whose presence causes instabilities in the accretion disk that allow material to fling upwards - as well as rapidly rotating black holes, which can feed some of their energy to the magnetic field and to the jet material itself."

In other words, it is the black hole itself that is causing the energy for the jet to be possible. And these jets happen outside the accretion disk. Meaning, outside of the zone where light is unable to escape. So no, you don't need faster-than-light speed when you're outside the accretion disk obviously.

You have to be able to visualize this phenomenon in your head to understand this.

Copy boss, so this means that the matter released is outside of the area where light can no longer escape. is this the event horizon?

Yes, pretty much. Sorry, wrong use of term on my post above. Replace "accretion disk" with "event horizon". I must still be asleep. XD

Thanks for the info bro.

No. Light is a particle and it has finite speed, meaning its speed remains the same no matter what. That fact is not easily bent without breaking the laws of physics.

No Matter can travel at the speed faster than light. What I'm saying is that it is not light itself that is being expelled from quasar jets but matter that is emitting light. Cosmic matter made up of helium, carbon, hydrogen etc.. That jet you see from quasars is cosmic matter being expelled.

So considering the fact that matter cannot travel at the speed of light, it is safe to assume that matter expelled from quasar jets are not travelling at light speed or faster. Although it is very very fast that it is almost chasing the speed of the light particles it is emitting.

The speed of light particles emitted from cosmic matter in a quasar jet remains the same. There is no increase in velocity.

Here are links to clarify what I'm saying:

you nailed it.. ehehehe.

Mao naning hinungdan sa sige nakog tan.aw og Sceince video. Hehehehe... hope na magamit jud kog telescope para maka kita og actual stars... naa bay pwede nato maabangan diri sugbo? kay mo abang jud ko...

[hanzheyteta]

very nice read.

[johnmar]

sauna pa, nitoo nako ani about threory of relativity.... atlis mas napa lawman pa ni karon.... grabe jud c einstien.... tungod nya it will shade another light for another discovery and theory waiting to be implemented in reality as we know it.... pwed jud ni mahitabo nga ma teletransport ang usa ka living tissue like us human or another living species..... d pani karon nga century mahitabo,im sure year 2100 0r 2200 pa. kay tungod sa LHC mao nay muhatag ug bag - ong principles and theory para mas mutaas pa ang level sa physics nga atong nahibaw-an as we know it.... by the way kitang tao cge man tag upgrade....heheheh exciting jud ang existence sa tao.... cguro gift ni nato para mas maka understand ta sa nakaingon nato nga ngano naa ta aning atong pagka consciuos nga nag exist ta.... hehehe balik balik ra ang storya...

[johnmar]

thats why karon samtang buhi pata.... ayaw sayanga imung kinabuhi make it valueble..... senseble... coz we dont know yet the .00000000000000000000000000001 about our life either dead or not.... just leave a usefull legacy while u are alive.... coz we dont know yet if maka experience pa ba kag balik ani atong namathan karon....

Ok im gonna pretend i actually understand this..
