# Travelling at/over speed of light, I fire a laser in front of me. What happens to the light from the laser? [closed]

For a moment, assume that travel at/over the speed of light is possible, and we fire a laser in front of us, what happens to the light emitted from the laser?

Would the photons scatter, or would the light only move at light-speed (that is to say, without a visible source).

Edit: To add to this, I realise that the light would be doppler-shifted.

• From the Help Center: Questions about physics of fictional worlds which are not sufficiently grounded in real physics are off topic here. This question is asking about a situation that is verboten with real physics. Aug 6, 2014 at 20:59
• An edit : assume that at or near speed of light travel is possible. If this question seems wrong then Einstein shouldn't have asked it too. Aug 6, 2014 at 21:29
• @AndresSalas, you've materially changed the question with your edit and, further, this edit makes the only answer given inappropriate. I consider this bad form and so I'm rolling back your edit. Aug 6, 2014 at 21:55
• It is possible to move faster than the speed of light in a medium, so I'm not sure it's appropriate to flag this question as non-mainstream physics. In that case, as always, the speed of the light is independent of the speed of the source. Aug 6, 2014 at 23:16
• @benrg: non-mainstream covers fictional physics. Surely photons can exceed $c_m$ for media $m$, but it does not mean that spaceships/people can exceed $c$. Aug 6, 2014 at 23:28
