Bob, Ed, and Sussie are all observers, each in their own space-ship. Ed and Sussie accelerate on parallel paths to very near the speed of light. Bob sees both length contraction and an increase in mass of both Eds and Sussies ships. These effects are great enough that each ship achieves the mass and density required to form an event horizon. Bob sees them fall together and become a single black hole moving at high speed.
Ed and Sussie accelerate simultaneously and remain at rest relative to each other. There is no reason that they should feel any irresistible attractive force (Unless Sussie is hot). After a period of time they slow down and are once again at rest relative to Bob.
How is the experience of Ed and Sussie reconcilable with the observation of Bob?
What does Bob see as Ed and Sussie slow down?
