There is a lightbulb exactly halfway between the front and rear of a long hallway in your spaceship. Your ship is traveling at 0.5 c relative to the earth. The bulb is suddenly turned on Let event 1 be when the light from the bulb first strikes the front end of the hall, and event 2 be when it strikes the rear end Which event occurs first, or are they simultaneous, in the frame of (a) the spaceship an (b) a person standing on the earth?
