Hey all! So, in my study of general relativity, I've come to understand that gravity is actually what physicists would have classically called a "fictitious force", in that it is a force derived from the fact that the observer is not in an inertial reference frame, like in the case of the centrifugal force. This makes a lot of sense to me due to the geometric nature of space-time. So when I hear particle physicists discuss Quantum Gravity theories, I get confused. Most propose some sort of unification of general relativity and quantum field theory, i.e. there is a force carrier for gravity called the "Graviton". This makes very little sense to me in the previous context of general relativity; how can a geometric, "fictitious" force be described by a quantum field of particles? Furthermore, how could the interaction of massive objects with this graviton field cause phenomena like time dilation and space-time, which follow naturally from the underlying premise of General Relativity that seems to be in direct conflict with modern attempts to unify gravity with the other forces? Thanks for reading!
