"Each action has an equal and opposite reaction".......?

Question

This is the third law of Sir Issac Newtons laws of physics. If it is true, then what is the reaction of a black holes action of pulling everything in due to its massive gravity?

Answer 1

Imagine you throw a ball up in the air. The action of gravity is to pull the ball towards the ground. The ball can't react to this until it hits the ground. When it hits the ground the ball will bounce back upwards. The equal and opposite reaction you're asking about is the force that makes the ball bounce back up in the air.

In the case of black holes, the reaction will occur when a planet "hits" a black hole. The problem is that because the gravity of a black hole is so massive, we can't see the reaction. So there's no way of telling what actually happens.

Remember that everything has a force of gravity, but things with less mass (people, footballs, etc.) are pulled towards more massive objects (planets, black holes, etc.) because these objects have a stronger force of gravity. The reaction of gravity can only been seen when an opposite force occurs. That is, when the ball hits the ground.

If for some reason you can't see the reaction, like a black hole not showing us, that doesn't mean there isn't a reaction. It simply means that we can't see it!

Answer 2

Due to lack of observation of The Event, it is very unlikley that you will get a factuall answer. In theory, and depending on wich theory to start from, the Event Horizon is a collapsed star that has an unkown event occuring at its proposed center. Most science believes that the event is a reversal or a massive gravitational crushing of objects. What is beyond that is purely speculation. The black hole, or Event Horizon has a theoreticall effect on most everything in or near its Gravitational Influence.
One Event Horizon could theoretically consume another if space was a collapsing universe could be changed in that way.

Answer 3

a black whole is not unique in constantly attacting things

all matter does that

the earth for instance is constantly sucking into it anything that drifts nearby

the force of a meteorite hitting the earth has an equal and opposite reaction of the earth hitting the meteorite

that is how all opposite forces apply

for example, in the classic horse pulls a wagon situation

the horse pulls on the wagon with a certain force
the wagon pulls back on the horse with an equal and opposite force

black holes behave in many ways that are very wierd but in the way they attract regular matter, it is not much different than any other massive body (like the earth or the sun)

Answer 4

I would say that the action of gravitational force is the reaction. It is the reactional force shared between whatever it is being pulled into the black hole, and the intensely super dense mass of the black hole itself. In other words, your application of the 3rd law is a little off, gravitational force is always a complete system of force between the two objects of the system. One acts on the other while being acted on by the other.

Answer 5

The reaction would be your "everything" pulling the black hole towards it, albeit on a far, far smaller scale. There's nothing mysterious about a black hole; it just attracts other matter due to gravity like anything else would.

Answer 6

The black hole gets pulled toward the in falling matter as the in falling matter gets pulled toward the black hole. The two move toward each other, the black hole does not stay in one place. But the heavier body moves less. If the black hole is a billion times as massive as the in falling matter, then it moves a billion times less, so without careful measurements it may appear as if the black hole were stationary, even though it really isn't.

Answer 7

Due to the EXTREME gravity of a black hole, anything going into it could be compared to the Earth's gravity and a pen falling off your desk to hit it. What is the equal an opposite reaction then?

Yup, you're right, it's so negligible, we can't measure it.

Same with a black hole....not to mention that we can't get close enough to it to see anything anyhow.

Answer 8

The correct answers are the ones about the black hole moving, but imperceptibly due to its colossal mass.

Beyond that answer, in reality there are no laws of physics.

Observations allow us to predict what will probably happen in a similar situation. Once we start saying there is a law that all elements of the universe must obey, then we start going badly wrong, because it isn't true.

There is the famous example of the scientist who, when told of the theory that meteors are rocks in space burning up in the atmosphere, stated this to be an impossibility because there are no rocks in space. He mistook his model of the universe for reality. In his model, perfect spheres move in beautiful and perfect orbits, in a perfect medium of crystal clear space - no room for random bits of rock flying about.

Answer 9

ıt may be the third law of Newton...but there is a natural law that says there are always opposıtes in nature....example right and left..up and down..salt and pepper..chalk and cheese...by this you may see that the distant reaction(hopefully) will be for all the contents of black holes to be redigested...a bit like the tide coming in and going out..is this useful?

Answer 10

If the increasing mass contributes to its gravity is not the attraction of more matter the reaction? Or is this perpetual motion and if so what was the initial action that began it all?
