First I want to say that I am a layperson, so I want intuitive answers.

So all the 3 fundamental forces in nature has a carrier particle except gravity. So we have hypothesized the existence of graviton. But I want to know that how does the concept of graviton relates to the concepts of general relativity which describes gravity as the curvature of space-time.

### So here are the Questions:-

$(1)$ Are gravitons consistent with the concept of curvature of space-time?

$(2)$ If the answer to $(1)$ is 'yes' then how does it account for gravitational waves which described as wobbling of space-time?

And if the answer to $(1)$ is 'no' then how does gravitons relate to curvature of space-time?

$(3)$ Blackholes are defined as an extremely curved region of spacetime with a singularity or a ring-singularity in the middle. So how does gravitons explain blackholes and singularities?

*(If this question is poorly framed then I am sorry, I cannot clarify more than this)*
