Hi all, I am not a physicist. Some engineer friends of mine and I have a question about special relativity in two dimensions. To set it up, there are 2 lights floating in space parallel to the x axis and a space ship is traveling at .8c flying parallel to the y axis towards the midpoint of the line connecting the lights. Then at some time, t, an observer, o1, between the lights at the midpoint flashes both of them simultaneously. I drew a quick diagram which is attached. 1. The observer o1 will see both flash simultaneously 2. At a different time t', the crew of the space ship will also see both flash simultaneously because of the symmetry of the problem. Is our understanding correct?
