This question already has an answer here:
In my perception of the universe, there's the theater which is the 'spacetime' and the actors meaning the 'particles'. If i got it right, GR claims that the 'actors' effect the 'theatre' by 'bending' it. Also in order to combine GR and QM, some beleive in the existence of the 'graviton'. Does this mean that the 'theater' is no longer needed since gravity is not a property of spacetime anymore? Does the hypothetical existaence of the graviton cancels out the spacetime and it's 'curvature'?
If gravity is 'transfered' trough 'gravitons' and its not a property of spacetime and its curvature, how can we explain its impact to EM transmision ? How does a particle (graviton) can influence the path of motion of another particle (photon) in space?
