Please answer if based on the above data do you confirm that:1. There are lot of particles in the wind between the BH and the starYes Or No?2. The BH "isn't a great eater and not many particles are crossing its event horizon" which means that we don't observe that it eats any particle from outside.Yes or No?3. If the BH doesn't eat all the particles Infront of his mouth, then its gravity force isn't strong enough to grab them.Yes or No?4. As the BH' gravity force it too weak to grab even those free nearby particles, then it is very clear that it also doesn't have enough gravity force to kick any particle from the companion star.Yes or No?5. Therefore, all the lot particles have not been ejected from the star due to the poor BH gravity forceYes or no?6. So how can we explain the existence of all the particles that are there in the stellar wind next to the mouth of the BH?7. How long are we going to dream about Bhs that eat food/Particles from outside, while BHs refuse to eat any?8. It is stated: "We don't know why that is, but we want to find out!"Don't you think that it's time to tell those puzzled scientists that their imagination about BH that could kick out particles from its companion star with its poor gravity force and eat them for breakfast is just incorrect?9. Is there any possibility that we would accept the real meaning of the observation?
In the article it is stated:https://www.space.com/newfound-black-holes-closest-to-earth-gaia"There are a lot of particles coming off the companion star in the form of stellar wind," Cendes said. "But because we didn't see any radio light, that tells us the black hole isn't a great eater and not many particles are crossing its event horizon. We don't know why that is, but we want to find out!"So, if the particles are coming out from the star (as they claim) due to the mighty BH gravity force, then why that BH doesn't eat those ejected particles (after they had been ejected from the star)?How could it be that the BH gravity force is strong enough to cut particles from the star but its not strong enough to direct them into its mouth?Sorry, this is not realistic.If the BH gravity force is strong enough to grab particles from the companion star, then as those participles are ejected outwards, its gravity force must grab them all and eat them.Therefore, I wonder why they are so sure that the star is the source for those particles?Did they really monitor/see the particles flow from the companion star or they just saw the stellar wind full with particles and they just assume that it must come from the star?If the BH has not enough gravity force to eat the particles, how can we believe that it had enough gravity force to kick them out from the star?Why they also discuss about particles? Why not Hydrogen or gas flow?Can we get further information about what kind of particles they really observe?
In any case, in this observation there is no indication for inflow into the BH itself as they clearly cleam that black hole isn't a great eater and not many particles are crossing its event horizon.
Stellar wind (or solar wind) is what is produced naturally by the star. It isn't being pulled off by the black hole.
(if the black hole has one — astronomers don't know).
Hence, Outflow is due to Magnetic fields and inflow is due to gravity.
As a black hole spins, its dense mass distorts and twists the surrounding fabric of space and time. The simulations show that magnetic fields at the poles of the black hole become coiled and spring outward, flinging jets of particles into space. At the equator, magnetic fields collapse into clumps. This tangling creates areas that act like particle accelerators, boosting some particles into the edges of polar jets at high speeds and others into the maw of the black hole.
"Solar wind consisting of charged particles and the sun's magnetic field."Therefore, this outflow is due to the Sun's Magnetic field
Quote from: Dave Lev on 18/04/2023 03:09:50Hence, Outflow is due to Magnetic fields and inflow is due to gravity.That isn't exactly a new idea (although energy extracted from the black hole's spin via the ergosphere probably also plays a role in outflow as well). You can have both inflow and outflow in the same system. We have done simulations and found that it is possible: https://www.simonsfoundation.org/2019/01/29/black-hole-plasma-jets/#:~:text=As%20a%20black%20hole%20spins,magnetic%20fields%20collapse%20into%20clumps.QuoteAs a black hole spins, its dense mass distorts and twists the surrounding fabric of space and time.

Can you please explain how could it be that they start the simulation without plasma and then particles are created?

So do you give me now the permission to reuse this message, or it is still forbidden?
It depends if you plan to stay within the laws of physics.
This is called a "pair plasma".
No new mass or energy is created, it is only transformed into a different kind of particle.
So let's see if I get it correctly:1. New particle pair is created near the SMBH' event Horizon by its EM power.2. That new created pair that is called "pair plasma" would be ejected into the accretion disc and be part of the plasma.
Do we all agree on the above understanding?

Electron-positron pair plasmas are abundant in high-energy astrophysical systems, such as those associated with neutron star and black hole environments. The interactions of photons with each other and with strong magnetic fields lead to prolific pair creation via electromagnetic cascades. These pair plasmas are typically hot and can be accelerated to high speeds in the winds or jets associated with these compact astrophysical objects, including pulsar magnetospheres, jets from active galactic nuclei and GRBs.
1. Can we agree that there is no need for any inflow as the plasma in the accretion disc had been created as a Pair plasma by the SMBH?
The inflow itself is what makes the pair plasma as I just explained. Without inflow, the black hole sits there and does nothing.
Actually, any outflow (even the one from the BH itself) is due to magnetic field.
I would like to focus on the inflow Hypothesis.
How could it be that we clearly observe the outflow from that Bh but we can't see any inflow while it is located so close to us?
As we have never observed any star as it falls inwards, could it be that there is an error in this inflow hypothesis?
Quote from: Dave Lev on 22/04/2023 17:11:52How could it be that we clearly observe the outflow from that Bh but we can't see any inflow while it is located so close to us?We don't observe any outflow from that particular black hole.
We know that there is inflow in many star-black hole binaries because the star is the only source of gas that the accretion disk could have acquired it from.

https://www.space.com/22215-solar-wind.html"Solar wind consisting of charged particles and the sun's magnetic field."Therefore, this outflow is due to the Sun's Magnetic fieldParker's theory describes how the magnetic field can overcome the gravity force:"Parker's theory described that in the sun's corona, plasma is continually heated with temperatures in this region reaching a blistering 3.5 million degrees Fahrenheit (2 million degrees Celsius). Eventually, the plasma becomes so hot that the sun's gravity can no longer hold it down so it is hurled into space as the solar wind, dragging the sun's magnetic field along with it, according to NASA JPL.
