The nature of gravity and black holes

Are black holes, by their very existence, proof that gravity is a warp of space-time and not transmitted by any kind of particle?

My reasoning goes something like this: the event horizon is the point at which a particle has to be travelling FTL to escape, exceeding c is impossible, black holes have gravitational effects, therefore gravity can't be transmitted via particles.

No. We don't have a good quantum theory of gravity, which means that we don't really know how to discuss gravity in terms of particle behavior.

It's important to remember that black holes are technically predictions of relativity that have not yet been confirmed. We know there are some *very* massive objects out there, and that their behavior is *consistent* with them being these things predicted by relativity, but we haven't yet managed to accurately image one. These objects are *probably* (very closely approximated by) the black holes of relativity, but we can't use their existence as evidence in favor of one gravitational model over another. Almost all of our understanding of black holes comes from models based on relativity theory, so one cannot take that information as being evidence for or against *other* models.
