Unless of course, space-time is curved (which supposedly it is by gravitational forces) in which case the light will follow the contour of space-time, still a straight line along that contour, but "bent".
If you did send a laser beam, I don't think it would have time to hit the "end" of the universe. As fast as light does travel, it takes years even to reach us from some stars.
