Are gravitons consistent with black holes emitting them?

[Firesmith]

If gravitons exist, how can black holes emit them? It cannot be like Hawking radiation, which increases as the black hole gets smaller. The gravitational field grows larger as black holes grow larger. Also, would not the energy of the graviton decrease to zero (and its wavelength increase to infinity) as a graviton rose from the event horizon? I don't see how gravitons and black holes are consistent concepts.

Sorry. I should have searched for this question before asking it again. Don't know how to delete this thread.

That said, I have a question relating one of the answers, which is to distinguish between actual and virtual gravitons. Supposedly, virtual particles can travel faster than the speed of light as long as they do not violate Heisenberg's uncertainty principle. This raises two further questions:
1) Does it make sense to say that a virtual particle travels faster than light, or rather that it in some sense tunnels from one location to another location without having to have moved between them?
2) If virtual particles travel faster than light (all travel faster? some travel faster? infinite speed?), then by moving a source of virtual particles back and forth should change the direction of the force felt by another particle faster than light, which would imply sending information faster than light. Or is this prevented by having the sideways movement of the emitter (at less than light speed) cause a change in direction of the resulting force to be too small to measure given Heisenberg's uncertainty principle?

The concept of gravitons and black holes is a complex and debated topic in the field of physics. Gravitons are hypothetical particles that are believed to carry the force of gravity. However, their existence has not been conclusively proven yet.

Assuming that gravitons do exist, it is possible for black holes to emit them. Just like how Hawking radiation is created by virtual particle pairs near the event horizon of a black hole, gravitons could also be created in a similar way. As the black hole's gravitational field is extremely strong, it could potentially create and emit gravitons.

The idea that the energy of a graviton would decrease to zero as it rises from the event horizon is based on classical physics. In the quantum realm, however, particles can behave differently and their energy can fluctuate. So, it is possible for gravitons to maintain their energy and wavelength as they are emitted from a black hole.

It is also important to note that the concept of gravitons is still a theoretical concept and there are many unknowns about their behavior and interactions with other particles. So, it is difficult to make definitive statements about their consistency with black holes.

In conclusion, the relationship between gravitons and black holes is a complex and ongoing area of research. While there may be challenges in reconciling these concepts, it is not impossible for them to coexist. Further studies and experiments are needed to fully understand the behavior of gravitons and their interactions with black holes.
