How does a black hole exert gravitational force?

Question

If gravity is indeed mediated by a particle, how does this particle exert influence beyond the event horizon?

Answer 1

The event horizon is simply the point at which light cannot even escape the black hole. Its gravitational effect still exists beyond the event horizon, it is just that light will be able to escape its gravitational pull past that point.

Answer 2

This is a very good question. The graviton is a theoretical particle proposed for mediating the force of gravity. The first issue is that black holes are predicted by Einstein's Theory of General Relativity which does not require or predict the existence of the graviton. The graviton is predicted by the Standard Model or Quantum Field Theory. To date, however, the existence of the graviton has not yet been confirmed.

If the graviton does exist, the answer to your question would be that the particle is not effected by the gravitational fields that it produces. Therefore, the gravitons would mediate the gravitational fields beyond the event horizon to exert the gravitational force on nearby objects.

Hope this helps

Answer 3

There's no scientific proof that any particle like a 'graviton' mediates gravitational force, or that it even exists.

What we call the 'force' of gravity was proven by Einstein to actually be a change in the shape of space-time caused by the presence of any mass. The mass of a black hole is so immense that space-time is distorted to the max...it's literally turned back on itself. Since everything in the universe is embedded in spacetime and must follow its shape (..geometry..) nothing can escape back into the 'normal' universe once caught by a black hole.

Answer 4

Science has never detected a "graviton." Einstein demonstrated that mass bends space and a black hole bends space back on itself so there is no path out of the black hole a particle like a photon could take to escape the black hole.

Another way to look at it is increasing mass increases the escape velocity of the body. At a certain point, the escape velocity increases beyond the speed of light. At that point, regular mass becomes a black hole.

Answer 5

The huge amount of gravity generated by the spinning mass of the imploded star causes a tear in the space-time continuum. A particle entering the even horizon is "spaghetiified" and stretched to infinity within the black hole.

Answer 6

A bb has gravity - billions upon billions of bbs multiply the gravitational tension incredibly attracting or pulling in much extra rely to develop the size of the mass till it collapses in on itself. The gravity overpowers the atomic shape of issues - electrons, protons etc. don't have sufficient space to orbit. Photons (mild debris with mass) in simple terms won't be able to beat the strain of the gravity created by utilising all this textile. So it incredibly is the persistent addition of mass that varieties the black hollow producing sufficient gravity to capture debris of sunshine and pull in much extra rely.

Answer 7

Black holes do not exert gravitation.

Gravitation needs two masses to have any physical meaning, so properly a black hole experiences a force between it and another massive object.

Nonetheless, your question is excellent and I look forward to more intelligent responses than my meager quibble.

Answer 8

the first person answered the question when they said densest object. every object has a gravitational force on every other object. objects with the greatest mass have the most pulling power... black holes are the most massive objects in the universe..

Answer 9

Gravitons certainly travel beyond the event horizon. Gravitons are not electro-magnetic radiation.

imagine a bed sheet is the fabric of space now put a bowling ball on the sheet ,that would be our sun curving space.now drive a car on this sheet which would be a black hole
