I'm not a great scientist or math guru, I was in the naval nuclear power program and only pursue physics as a hobby. My question is this: according to Einstein gravity results from the curvature of space. If that is so wouldn't it be reasonable to say that gravity is an effect resulting from the curvature of space? Just like centrifugal force isn't really a force at all, but an APPARENT force resulting from the laws of inertia? If that is correct, why try to unify gravity with the other three forces? We don't try to unify centrifugal force with them, or am I way off base? Any replies would be appreciated.
