If you have a moving light bulb and an observer at rest wrt the light bulb. The observer is tiny and he is inside the light bulb. The light bulb is travelling along the x axis. The light is then turned on what will the observer see..a sphere of photons travelling outwards from the observer? Keep in mind if you are in a space ship travelling in the direction of the x axis and there is a a laser trained on a spot along the Y axis . Regardless of the velocity of the frame of reference the laser will always remain trained on the spot. so if the frame goes faster the photons from the laser will "bend" more so they remain on the spot Therefore photons travelling perpendicular to the direction of travell MUST bend more than non perpendicular photons. The amount a photons bends is propriotional to the angle the photons makes wrt the x axis. Photons travelling along the x axis will not bend at all. Therefore the photons cannot form a sphere around the observer as they are not all bending by the same amount. The shape formed wiil be a skewed sphere or a shapes that is NOT an sphere... is there something I am missing here?
