I would like to change the speed of light, or failing that, the fact that you can't go faster than it. I find this fact quite serially inconvenient.
What I love about this shot, incidentally, is Han and Chewie's total non-reaction to what is happening outside. Han doesn't even look up until after the effect begins, a bit like a driver might pull away from the kerb before properly looking at the road ahead. In reality this could be because both actors were staring at a blue screen beyond the cockpit windows - but in terms of the story it underlines just how unspectacular and normal a hyperspace jump is.
