A big thanks to you guys for clarifying my doubts, especially Doc Al and his detailed explanation, and also Janus' animations.

If the spaceman don't know anything about physics, not only would he think the explosions are simultaneous, he would also think that the Earth is flat.

Yup, that's what I meant.

LURCH, your explanation sounds plausible, but I'm assuming that the ship is indeed physically at the midpoint between points A and B. Drawing a rough space-time diagram (see attached file), with really bad symmetry ( the gradient for both light from A and from B should be perpendicular...

Just to be sure if I got you correct, Because if both bulbs were turned on simultaneously, I (on the moving ship) would see the bulb at B turn on first. Therefore if I am on the moving ship and I saw the 2 bulbs turn on simultaneously, it would mean that the bulb at A was turned on earlier...

Suppose if I am in a ship traveling from points A to B (10 light years apart) at a relavistic speed of say 0.8c. Then suppose if there is a very strong light bulb at both points A and B, and assuming that the light rays do not get weakened along the way. Now if I am in the ship moving from...
