Dude what a channel I just found with yours. Subscribed

Many thanks, Chris, for another fascinating video on black holes and the reason behind the formation of super bright and super long jets. The mind truly does boggle! Nearly all images of jets give the appearance of them coming from within the event horizon of heavy black holes, so it is great you have corrected these visual images. I suppose ultimately black holes are so utterly weird and wonderful we just have to accept at present that this is how the universe works at the extreme boundaries of what exists as can be understood. Am I correct in assuming that jets are in no way link to Hawking radiation, which, so far as I know, hasn’t been detected? A video on the black hole information paradox would be greatly appreciated. Again, my appreciation for the time and effort you put into producing these videos, Chris. You have the gift of making the complex comprehensible

Thanks David! You are correct that the jets aren't related to Hawking radiation, which is a purely quantum process. As you correctly say, we have never seen Hawking radiation, or even any evidence to even suggest it, it is still a purely theoretical idea. It's also incredibly slow and inefficient, whereas these jets are jets fast and powerful. Great question though, and my video would have benefitted from me mentioning these differences! Thanks as always :)

This just blew my mind, I didn't know hawking radiation hasn't been proven yet.

Galaxy reside in a gravitational bubble. The gravitational field is weakest at the center of Galaxy along its axis of rotation or polar regions which allow the swirling material from acretion disc to escape.

Good video 🙌

Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "the essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. This is illustrated in a common 2 axis relativity graph with velocity on the horizontal line and dilation on the vertical. Even mass that exists at 75% light speed is partially dilated. General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in black holes when he was alive for this reason. Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy. According to Einstein's math, the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. This is the explanation for the abnormally high rotation rates of stars in spiral galaxies, the missing mass is dilated mass. According to Einstein's math, galaxies with very, very low mass would show no signs of dark matter because they do not have enough mass at the center to achieve relativistic velocities, therefore they are not infused with dilated mass. This has been confirmed with galaxy NGC 1052-DF2.

The shape of a galaxy is common in nature. From atoms to our solar system, the overwhelming majority of the mass is in the center. The same must be true for galaxies. Where there is mass there is energy. The night sky should be lit up from the galactic center but it isn't. The modern explanation for this is because gravitational forces there are so strong that not even light can escape, even though the mass of the photon is zero. Einstein's answer would be because the mass there is dilated relative to an Earthbound observer. This was the accepted explanation until television and movies popularized black holes in the 1960's. Belief in them gradually came to be despite the fact that Einstein said that they cannot exist and there was no evidence. The modern idea that there is some way to take a "picture" of the galactic center is absurd. The interference alone, dilation alone or gravitational lensing alone would make that virtually impossible. As per relativity, an observer would have to exist at or near it's momentum.

So basically just magnets and spinning? 😉

Hi Chris. Is it a positively charged jet of plasma in one direction and negatively charged plasma in the other?

Well, I have a really big question. Can't they use the event horizon telescope to capture direct images of exoplanets?

Well, event horizon is not an optical telescope to see other planetary sources. It is a radio telescope that receives the radio signal from the radio sources. So actually, the black hole pictured by event horizon is a radio image. So event horizon for exoplanet searches - is not possible.

Jet because of inside black hole turbulence. Assume every nature describe word has an answer.

omg. I thought you were going to talk about the PHYSICS of black hole jets. I was hoping for an explanation of the Blandford-Znajek process. Instead I got a bunch of whiz bang images. Very disappointed.

Cause they got gas.

But you said nothing can escape a black hole?
