So I know gravity correlates with time dilation. If you have two individual equal size black holes close to each other, then at a point between them, gravity is equal to zero. Would the time dilation at that point be a sum of each individual black holes gravity or would the two time dilation effects cancel out making the speed of time at that point equal to the speed of time at a point in the middle of space somewhere? I know my question probably has a few misunderstandings in it, but I believe what I am trying to ask is evident. Please help!
