How does a black hole manage to vacuum up the gas and dust orbiting around it? Here's my own Answer,Yes or No?

Question

Just like the mechanism that keeps planets orbiting the Sun, angular momentum should keep this gas and dust coasting around black holes forever.
However, Could it be true that the reason that black holes are able to achieve this great feat is from the momentum itself left from the implosion? that the particles around it were once a part of the star that created the black hole? Therefore, A black hole can and will only grow to be as big as it once was, when it was a star.
It could be possible that the particles around a black hole are minute compared to the actual size of the existing black hole and therefore were not sucked up by the initial implosion.Newton's 3rd Law explains, the reaction must be equal and opposite the action, but it does not say anything about the method of the reaction, just that it must be equal in the end. This process could take millions of years to complete, and it would be true, right? Then particles sucked into a Black Hole might have once been part of it.

Answer 1

You seem to ignore gravity completely!!!! A very weak gravitational field acting on a body of any mass will have an effect on it however slight and attract it. As it gets closer the gravitational pull will grow exponentially until it is hurtling towards the source.

Have you not seen the pictures of the black hole that is actually consuming two galaxies?

I think you will find there is a wealth of information out there on black holes and the vast majority of it based on scientific facts and theories.

Answer 2

You are right. Matter would orbit a black hole in precisely the same way as it would the original star *if* everything else was equal. However, the magnetic fields around a black hole is much more intense than around the original star. This field can acquire some of the angular momentum, allowing things to fall into the hole. Recent calcualtions seem to suggest that this effect is enough to explain the observed in-fall rates.

Answer 3

THere are several mechanisms that could be at work here. Collisions between particles can result in transfer of momentum, leaving one particle headed for the hole. Radiation losses, due to particles interacting with the hole's magnetic field, are another, and this one is fairly likely based on radiation seen coming from the vicinity of what we think are black holes. The bottom line is that there are means by which a black hole could grow, and it is not unlikely that they do so.

Answer 4

I am not sure I really understand your answer, but a black hole is always extremely massive therefore, the gravitational pull exerted can drag pretty much anything in it as long as they aren't too far. Applying Newton's 3rd law to black hole astrophysics is simplifying matters a bit too much. The black hole will absorb whatever is within the Scwarschild radius and whatever will eventually go in that radius. The only way to stay out, is to rotate extremely fast at a distance that is bigger than Scwarschild Radius. So No...

Answer 5

Theoretically you could acheive an angular momentum, but to do that you would have to be so far from the black hole that it would not be caught to close to the gravitational center. Gravity weakens the further you are from something. However, if you are close enough to a black hole to think of yourself as in orbit aroud it, then you are close enough that the gravitational force is greater than the centrifugal force that would keep the object in orbit.

Answer 6

If something is far enought out, and moving at the correct trajectory to begin with, then it should orbit the black hole forever. Collisions and near misses between objects will send these bodies on a different trajectory, however ....

Answer 7

Yes. An object could orbit a black hole, or fall into one, or swirl into it, just like objects orbit or fall into the earth. All depends on the approach trajectory and velocity.

Answer 8

It could be related to the speed of the angular momentum.

The relation between the speed and the mass means that any colision will generate a lot of heat that will degenerate the orbit.

Also the speed might generate magntic fields that also will generate heat...

Answer 9

there are theories concerning it but it is not yet proven because blackholes are not subjected to experiments and just a little observation. perhaps there are other forces not yet known by science which is responsible for the sucking force of the black hole.

This would probably be a very interesting article for you to read on the subject, from the Hubble archives:
