: A rocket traveling at .3c is approaching two events (flashbulbs) A and : B located at xA = 20 and xB = 30 and occurring at : t = 0 then:

: tA' = [0 - (.3)(20)] / [1 - .32]1/2 : = - 6.3s : and tB' = [0 - (.3)(30)] / [1 - .32]1/2 = : - 9.4s

: What does this mean? It can't mean that an observer on the rocket sees : event B occur before event A can it?

The Lorenz transformation equations don't give you when events are seen. They give you when they actually occur. It means that the two events that are simultaneous in one coordinate frame are not simultaneous in the other coordinate frame. Simultaneity is relative, not absolute. Not only do the two coordinate frames have different standards of length and time intervals but they also have different standards for simultaneity.
