 Okay, so if we plug this into the Lorentz transformations, we get delta XB equals gamma LA. So the length Bob measures between these two events is gamma multiplied by the length Alice measured. But wait a moment. Gamma is greater than one. So this is saying that Bob will measure a distance bigger than what Alice measures. This is like some kind of length expansion formula rather than a length contraction formula. So somewhere along here in our line of reasoning, we've made a mistake. Can you spot what that is?
