U is the universal rest frame. A and B space ships pass U at t=0, moving at v. Both experience equal length contraction in the x direction.
If length contraction is a result of em deformation in response to acceleration, then length expansion should be the response to deceleration. If the B ship slows to v=0 between t1 & t2, it should recover its original length.
According to SR, if B moves away from A, A should measure a length contraction of B.
So what happens?
